ElettrologiaCampo magneticoCampo geomagneticoDETERMINAZIONE DELLE COMPONENTI ORIZZONTALE E VERTICALE DEL CAMPO GEOMAGNETICO.UE3030700 04/16 MEC/UDFig. 1: Disposizione per la misurazione.BASI GENERALILa terra è circondata da un campo geomagnetico, prodot-to dalla cosiddetta geodinamo. In prossimità della super-ficie terrestre il campo è simile al campo magnetico gene-rato da un dipolo, le cui linee di campo partono dall’emisfero terrestre meridionale per poi rientrare nel’emisfero settentrionale. L’angolo tra la direzione del campo geomagnetico e il piano orizzontale viene detto inclinazione. La componente orizzontale del campo geo-magnetico corre essenzialmente parallelamente alla dire-zione nord-sud. Poiché la crosta terrestre è magnetizzata in modo diverso, si verificano scostamenti a livello loca-le; questo fenomeno è denominato declinazione.Fig. 2: Rappresentazione delle componenti dei campi magne-tici esaminati nell’esperimento e definizione del rel ativo angolo.Nell’esperimento vengono esaminati l’inclinazione e l’intensità, nonché la componente orizzontale e verticale del campo geomagnetico nel punto di misurazione. Si applica la correlazione (Fig. 2):(1) v h tan B B =⋅αα: InclinazioneB h : Componente orizzontale B v : Componente verticale e(2) B È pertanto sufficiente determinare le grandezze B h e α, per poter determinare anche le altre due.L’inclinazione α viene rilevata utilizzando un inclinatorio. Per determinare la componente orizzontale B h lo stesso inclinato-rio sull’orizzontale viene orientato in modo tale che l’ago di bussola integrato, che tende a disporsi parallelamente alla componente orizzontale, sia puntato sullo 0. Una coppia di bobine di Helmholtz genera un campo magnetico orizzontale supplementare B HH perpendicolare a B h determinando la rotazione dell’ago di un angolo β.

3B SCIENTIFIC ® PHYSICSInstruction sheet12/16 SD/JSThe demo-multimeter is an electronic meter fea-turing a double scale for analog measurement of current and voltage in demonstration experi-ments. It is suitable for use as a free-standing in-strument or for setting up in training panel frames. The meter can handle measurements of current and voltage values and also allows the zero point to be set up in the centre of the scale for meas-urement of DC quantities. All the possible meas-uring ranges can be selected by means of a sin-gle rotary switch.This equipment is protected by fuses and au-tho-rised for making measurements in circuits directly connected to the low-voltage mains via plugs (CAT II), i.e. for measurements on house-hold appliances, for example. The current measuringranges are resistant to long-term overloading up to 10 A. Generous protection of all the current ranges by means of semiconductor circuit break-ers prevents the fuse blowing unintentionally in many cases.Switching between measuring ranges does not break any circuits connected to the equipment. This means it is possible to carry out measure-ments on voltage converters, for example, with-out causing induction surges. Resistance R , con-ductance G, impedance Z and admittance Ycan easily be determined as quotients of current and voltage measurements thanks to the non-inter-rupting switch capability without the need to change the wiring.The demo multimeter conforms to safety regula-tions for electrical measurement, control and la-boratory equipment, as specified in DIN EN 61010-1, protection class 2 and to measuring ca-tegory CAT II for up to 600 V. The nominal volt-age between the phase conductors and the neu-tral for voltage and current measurements (in cir-cuits directly connected to mains electricity) must not exceed 600 V in order to conform to CAT II. The meter is intended for measurements within its measuring ranges and in a measuring environ-ment as described in detail in the course of this manual. Safe operation of the multimeter is gua-ranteed if it is solely used as specified. Safety can-not be guaranteed, however, if the multimeter is used incorrectly or handled without due care and attention. In order to avoid serious injury due to current or voltage shocks, the following safety in-structions are to be observed at all times.The multimeter may only be used by persons who are able to recognise the risks of contact and take due precautions to avoid them. Voltages in ex-cess of 33 V AC (RMS) or 70 V DC are to be re-garded as actively dangerous if the current, charge or energy stored should exceed certain values (see DIN EN 61010-1).∙Carefully read the instruction manual before using the multimeter and obey the instruc-tions therein.∙The multimeter may only be used in a dry, dust-free environment with no risk of explo-sions occurring.The assumption needs to be made that unfore-seen voltages may be present in the vincinity of objects being measured (e.g. faulty equipment). ∙Before using the multimeter, check the hou-sing and measuring leads for damage and if there should be any malfunctions or visible damage, the multimeter is not to be used.Pay specific attention to the insulation for the measuring sockets.∙The multimeter may not be used to make measurement on circuits which exhibit co-rona discharge (high voltage).∙Particular care is to be taken when making measurements on high-frequency circuits where dangerous voltages may arise due to superimposition of components.∙The authorised measuring range is not to be exceeded. If measurements are made when the magnitude of the variable is unknown, al-ways select a large measuring range before shifting down to lower ones. ∙Make very sure that the voltage value be-tween the measured contact and earth or be-tween the ground socket and the measure-ment socket does not exceed 600 V.∙Before using the analogue multimeter to check that a voltage source is not exhibiting any actual voltage, check that the meter is working properly by selecting the battery test function.∙When measuring current, make sure the electricity is turned off before the analogue multimeter is connected into the circuit.∙When making measurements, always con-nect the ground lead first. Disconnect the sig-nal measurement lead before unplugging the ground.∙Turn off the multimeter before opening the casing, disconnect the power to the circuit and the measuring leads from the multimeter. If measurements are made where there are any risks of coming into contact with electricity, a sec-ond person is to be informed.∙The demo-multimeter should not be stored, set up or operated within reach of children. ∙When the multimeter is used by teenagers, trainees etc., a suitable person should super-vise to ensure the equipment is used safely. ∙If measurements are to be made where volt-ages exceed 33 V AC (RMS) or 70 V DC, be especially careful and only use safety experi-ment leads.Measuring categories according to DIN EN 61010-1.CAT I or unstipulated: Approved for measure-ments in circuits which are not directly connected to the low voltage mains grid (e.g. batteries). CAT II: Approved for measurements in circuits which are directly connected, by a mains lead and plug for instance, to the low voltage mains grid (e.g. household or office appliance and lab equipment).CAT III: Approved for measurements in circuits which are part of a building’s wiring installation (e.g. stationary consumers, distribution terminals, appliances connected directly to the distribution box).CAT IV: Approved for measurements in circuits which are directly connected to the source of the low voltage mains (e.g. electricity meters, main service feed, primary excess voltage protection).Scales: 0 … 10, linear0 … 3, linearScale length: 160 mmPointer deflection: 0…90°Electricalzero-point offset: in all DC rangesMeasurements:Voltage ranges: 0.1/ 0.3/ 1/ 3/ 10/ 30/100/ 300/ 600 V AC/DC Current ranges: 0.1/ 0.3/ 1/ 3/ 10/ 30/100/ 300 mA AC/DC1/ 3/ 10 A AC/DCInput resistance: 1 MΩ AC/DCVoltage drop whenmeasuring current: 100 mV approx.

二、概述GY-315钳形接地电阻测试仪适用于电信、电力、气象、机房、电力配电线路、铁塔输电线路、加油站、工厂接地网、避雷针等。
随着我国城市化发展，使得用传统的打地桩方法测量，接地电阻越来越困难。
主要是接地体周围找不到土壤，它们全部被水泥覆盖，即使有街心花园，但它们的土壤也往往与大地的土壤分开，更何况传统方法打辅助电极时对辅助电极的相对位置有要求，要找到满足此要求的土壤，在许多情况下是更加困难。
该仪表具备了无辅助地极测量的独特功能，改变了测试接地电阻传统的测量原理和手段：采用二电极测量原理和利用钳口测量技术无需打辅助地极，也无需将接地体与负载隔离，实现了在线测量。

I nhibit function can be used to avoid relay operation when not desired (maintenance, transitions).The LED's indicate the state of the alarm and the output relays.Measuring voltage ranges DirectInternal resis.Max. volt.Selectable by DIP-switch 0.1 to 1 V AC/DC >10 k Ω7V 1to 10 V AC/DC >10 k Ω20 V 0.4 to 4 V p AC> 10 k Ω100 V -1 to 1 VDC(DIC01>10 k Ω7V -10 to 10 VDC only)> 10 k Ω20 V Max. voltage for 1 s100 VNote 1:The input voltage cannot raise over 300 VAC/DC with respect to ground (PIC01 only)DIC01PIC01Mounting Output Supply: 24 to 48 VAC/DC Supply: 115/230 VAC DIN-rail 2xSPDT DIC 01 D D48 AV0 DIC 01 D B23 AV0Plug-inSPDTPIC 01 C D48 AV0 PIC 01 C B23 AV0}DIC01, PIC01General SpecificationsDIC01, PIC01Mode of OperationD I C01 and P I C01 monitor both AC and DC current and voltage.

CM-IWM.10Insulation monitoring relayThe insulation monitor CM-IWM.10 provides best and up to date insulation monitoring of modern IT systems in an optimum and state of the art way fulfilling the relevant standards. The device can be used in the most flexible way for AC, DC and AC/DC systems even with large leakage capacity to earth (PE). The adjustment of the setting values is simple and user friendly done on 2 rotaryswitches on the front of the device. Via LEDs the measured value, device parameters and device status are indicated easy to read.Benefits–Preventive fire and system protection–Quick fault localisation through selective earth fault detection to L+ and L- –Universal application in non-earthed DC / AC and mixed IT networks with maximal up to 1000 V measurement voltage–Suitable for large earth leakage capacitances up to 1000 μF–Simplest setting via engaging rotary switches–For monitoring photovoltaic system, also with thin-film technology–Optimised measuring times – normally shorter than with known methods–Monitoring also with voltage-free mains –Measuring circuit with broken wire detection –No additional coupling device requiredOrder dataCharacteristics–Insulation monitoring according to IEC/EN 61557-8–Detection of symmetric and asymmetric insulation faults – 1 c/o contact each for prewarning and warning –Prewarning threshold setting range: 20 kΩ ... 2 MΩ –Warning threshold setting range: 1 kΩ ... 250 kΩ –Open- or closed-circuit principle configurable–Setting the maximum earth leakage capacitance toshorten the response time–Simple, clearly arranged adjustment of the device withscrewdriver–LED chain to indicate the current insulation resistance –Display of active measuring circuits –Automatic and manual device self-test –Alarm storage selectable–External test and reset pushbutton can be connected –Width 90 mm–Various certifications and approvals (see overview,document no. 2CDC112250D0201)2C D C 251 002 S 0016Application / monitoring functionInsulation monitoring of:–Non-earthed DC / AC and mixed IT networks–UPS systems–Networks with frequency inverters–Battery networks–Networks with direct current drives–Photovoltaic systems–Hybrid and battery-powered vehiclesThe CM-IWM serves to monitor insulation resistance in accordance with IEC/EN 61557-8 in unearthed IT AC systems, IT AC systems with galvanically connected DC circuits, or unearthed IT DC systems.The insulation resistance between system lines and system earth is measured. If this falls below the adjustable threshold values, the output relays switch into the fault state.When applying control supply voltage the green LED …PWR“ turns on and an internal selftest of 10 s starts, where the LEDs of the indicator string light up in sequence. After this, measurement of the insulation resistance in the measuring circuit begins.Insulation measurement between terminals L(+) / L(-) and PE / KETerminals L(+) and L(-) are connected to the mains to be monitored. Broken wire detection, constantly effective during operation, generates an error messages if both terminals are not connected with low resistance through the mains.In addition, the two terminals PE and KE must be connected to the protective conductor system via separate lines. An error message is given here as well if a line is interrupted (see section …Actions in case of connection faults“).If the main measuring circuit is activated, an active measuring voltage with alternating polarity is applied between L(+) / L(-) and PE / KE to measure the insulation resistance. During the measuring phase with positive polarity, the "Active" LED flashes with a long ON-phase and with negative polarity with a short ON-phase.The length of the positive and negative measuring phases depends on the settings on the rotary switch "CE/μF", the actual leakage capacitance of the monitored network and with DC networks, on the level and duration of possible mains voltage fluctuations. Correct and preferably quick measurement is thus given with different mains conditions. In the event of particularly adverse conditions and major interferences, the measuring analysis can be steadied and delayed in addition with rotary switch "tv" if necessary.The current insulation resistance is determined and analysed at the end of each measuring phase. The LE D-chain shows the resistance determined, and the output relays for prewarning "VW" and alarm "AL" switch according to the respective response values set. If the response thresholds have been undercut, the LEDs "VW" or "AL" light according to the insulation fault location: "+", "-" or "+" and "-" simultaneously for AC faults or symmetric insulation faults.Storing insulation fault messageIf terminal R is open, the insulation fault messages (relay, LEDs) are stored when the respective response value is undercut, but also when the insulation resistance returns to the OK-range. In addition, the temporary minimum values of the insulation resistance are indicated on the LED chain through dimmed LEDs.If the "Reset" button on the device front is pressed or terminal R is connected with G, the stored insulation fault messages are reset when the insulation resistance is again in the OK-range.Output relay for insulation fault messagesThe rotary switch "CE/μF Rel." allows selecting the open circuit (A) or closed circuit (R) operation for the output relays "AL"(contacts 11-12-14) and "VW" (contacts 21-22-24).With the open circuit operation, the relays respond when the response values are undercut, with the closed circuit operation they release when the response values are undercut.If 2 different response values are not needed, "VW" and "AL" can be set to the same value. The output relays switch together in this case.2 - CM-IWM.10 | Data sheetBroken wire detectionAs mentioned above, all terminals of the measuring circuit are constantly monitored for wire breaks - not only at Power-On ora manual or occasional automatic test. The response time of monitoring is only a few seconds.Broken wire detection between L(+) and L(-) is performed via coupled alternating voltage. This alternating voltage is short-circuited if the terminals are connected to the connected mains at low-resistance. The device detects that the mains to be monitored is properly connected. Since this broken wire detection is carried out with alternating voltage, large earth leakage capacitances should be avoided between L(+) and L(-), since the capacitive reactance of these capacitances also short-circuits this alternating voltage. The device would no longer detect a connection fault on L(+)/L(-). Especially parallel lines should be prevented over larger distances.Device test functionsPrincipally, 2 different test functions are implemented: The "self-test" and the "expanded test":The self-test of the device is performed automatically after Power-On and every 4 operating hours. It can also be triggered manually at any time by pressing the "Test" button at the device front or with an external pushbutton connected between terminals T and G.With the self-test, contrary to the expanded test, the status of the output relays is not affected; the sequence is as follows. Switching to the negative measuring phase is performed for 4 s. The "Active" LED flashes Y and the LEDs of the LED-chain are selected in sequence and the internal circuit is checked. After this, switching to the positive measuring phase is performed for 4 s. The "Active" LED flashes Z and the LED-chain cycles again and additional internal tests are performed. Insulation measurement continues normally after a pause of 2 s if no faults have occurred.The expanded test is started when the internal or external "Test" button is pressed (or is still held) at the end of the 8 sec self-test, described above. The sequence is the same as with the self-test (2 measuring phases at 4 s + 2 s pause); however, the output relays "AL" and "VW" as well as the associated LEDs switch to the alarm state.If the Reset button is pressed during the 8 s or terminals R-G are connected, the expanded test is terminated after these 8 sec. Otherwise, the phases of the expanded test are constantly repeated, and, in addition, the "ERR" LED is on. However, the expanded test is terminated as soon as the Reset button is pressed. The device switches to the OK-state and restarts insulation measurement.Behaviour with internal device faultsIf internal device faults were detected during the test function, the LE D …E RR“ is lightening and the measuring circuit is deactivated internally. The LED …Active“ turns off. The output relays …AL“ and …VW“ as well as the corresponding LEDs switchto the alarm state and all LEDs of the LED chain turn off.Behaviour with connection faultsMeasurement is suspended if a line interruption is detected at terminals L(+) / L(-); the LED …Active“ turns off. This broken wire detection is signalled by flashing S of the LED …ERR“. The output relays …AL“ and …VW“ as well as the corresponding LEDs go into alarm state and all LEDs of the indicator LED chain turn off.Measurement of the connection insulation resistance restarts after the connection interruption has been corrected. However, stored alarm messages are preserved.If the connections PE/KE to the protective conductor system are interrupted, the same responses take place as with an interruption at terminals L(+)/L(-), only that the LED …ERR“ flashes differently: U.Data sheet| CM-IWM.10 - 3Function diagram4 - CM-IWM.10 | Data sheetElectrical connectionConnection examplesData sheet| CM-IWM.10 - 5Operating state indicationLEDs, status information and fault messagesPWR:green LED V control supply voltage appliedERR:V internal device errorred LEDS connection error L+/L-U connection error PE/KE Active:Z measuring phase with positive polarity green LEDY measuring phase with negative polarity LED chain:yellow LED V8 LEDs indicate the current insulating resistance (m 10 k q ...

Please observe sufficient distance to terminals of neighbour devices and to the grounded metal cabinet or box (min. 0.5 cm).• The terminals of the control inputs T, R and G have no galvanic separation to the measuring circuit L(+) and L(-) and are electrically connected together, therefore they have to be controlled by volt free contacts or bridge. These contacts or bridges must provide a sufficient separation depending on the mains voltage on L(+)-L(-).• No external potentials may be connected to control terminals T and R. The associated reference potential is G (identical with PE), and the connection of the terminals is made via bridges to G.Attention!• Before checking insulation and voltage, disconnect the monitoring device from the power source!• Only one insulation monitor may be active in a network to be monitored, since the devices wouldotherwise influence each other. When coupling several networks or incoming feed sections, where each of them is equipped with its own insulation monitor, all of them must be deactivated except for one insulation monitor.• Device terminals PE and KE must always be connected via separate lines to different terminal points of the protective-conductor system.• The device must not be operated without KE/PE connection!• The measuring circuit should not be connected via longer parallel guided wires, as this may interfere with the broken wire detection. Also large capacities between L(+) und L(-) have to be avoided.Important!• The measuring circuit can be connected with its terminals L(+) and L(-) both to the DC and also AC side of a mixed network; it is done most practically where the primary incoming power supply takes place. Selector switch "t v / U N " should be set accordingly.For photovoltaic systems and hybrid vehicles, the measuring circuit of the CM-IWM is connected on the DC side; the auxiliary measuring circuit can then be used to monitor the (deactivated) AC side.• If a monitored AC system includes galvanically connected DC circuits (e.g. via a rectifier), an insulation failure on the DC side can only be detected correctly, when a current of min 10 mA can flow via the semiconductor connections.• If a monitored DC system includes galvanically connected AC circuits (e.g. via an inverter), an insulation failure on the AC side can only be detected correctly, when a current of min 10 mA can flow via the semiconductor connections.• The measuring circuit is designed for large leakage capacitances up to 1000 μF. The selection switch "CE/μF" must be set accordingly. Measurement of the insulation resistances is not falsified by this; however, longer periods are required for the measuring phases than with small capacitances. If the maximum approximate leakage capacitance is known, the selector switch "CE/μF" can possibly be set to smaller values, which reduces the response time further.• For the main measuring circuit, the nominal voltage range for DC is specified with 690 V; however, absolute values up to max. DC 1000 V are permissible.• This is a Class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.• This device is designed for IT systems with symmetric system leakage capacitances. With highlyunsymmetrical leakage capacitances, the device may not work the way it was intended.Technical dataData at Ta = 25 °C and rated values, unless otherwise indicatedInput circuitRated control supply voltage U S24 V DCVoltage range20-30 V DCTypical power consumption max. 5 WMeasuring ciruitControl inputbetween T, R and G Current flow approx. 3 mANo-load voltage to ground approx. 12 VPermissible wire length< 50 mMin. activation time0.5 sOutputContacts 2 x 1 c/o contacts for VW and ALThermal current I th 4 ASwitching capacity to AC-15n/o contact 3 A / AC 230 V acc. to IEC/EN 60947-5-1n/c contact 1 A / AC 230 V acc. to IEC/EN 60947-5-1 Electrical life at 8 A, AC 250 V 1 x 104 switching cyclesShort circuit strength max. fuse rating 4 A gL acc. to IEC/EN 60947-5-1Mechanical life10 x 106 switching cyclesGeneral DataOperating mode Continuous operationTemperature range operation- 25 ... + 60 °Cstorage- 40 ... + 70 °C Relative air humidity93 % at 40 °CAtmospheric pressure860-1600 mbar (86-106 kPa)Altitude IEC/EN 60664-1< 4000 m8 - CM-IWM.10 | Data sheetClearance andcreepage distancesRated impulse voltage / pollution degree IEC/EN 60664-1Measuring ciruit L(+) / L(-) to auxiliary voltage DC and relay contacts VW, AL8 kV / 2 auxiliary voltage DC to relay contacts VW, AL8 kV / 2 relay contacts VW to relay contact AL 4 kV / 2Insulation test voltage, routine test AC 5 kV; 1 sAC 2.5 kV; 1 sTechnical dataEMCElectrostatic discharge (ESD)IEC/EN 61000-4-28 kV (air)HF irradiation IEC/EN 61000-4-380 MHz-2.7 GHz: 10 V/mFast transients IEC/EN 61000-4-4 4 kVSurge voltages IEC/EN 61000-4-5betweenA1 - A2: 1 kVL(+) - L(-): 2 kVA1, A2 - PE: 4 kVL(+), L(-) - PE: 4 kVcontrol line: 0.5 kVcontrol line and earth: 1 kVHF-wire guided IEC/EN 61000-4-610 VInterference suppression EN 55011Limit value class AWhen connected to a low voltage public system (Class B,EN 55011) radio interference can be generated.
