PRODUCT FEATURES2.1 DESCRIPTIONThe AmpFlex® is a flexible AC current transformer composed of a flexible sensor and an electronic module. The flexible sensor permits measurements on conductors where standard clamp-on probes could not be used. In particular, it can be installed in tight spaces, around breaker panels, around cable bundles, around wide or large bus bars, or even wrapped around irregular shapes. The Shape Memory feature enables the user to “pre-shape” the sensor before inserting it between or around conductors. This feature facilitates closing, enhances user safety, and alleviates the drooping effect typically associated with flexible sensors.The AmpFlex® is lightweight and does not use magnetic cores like standard transformers. The transformation principle is based on an air core. It presents virtually no load to the system under test, has a low phase shift, has excellent frequency response, and cannot be damaged by overloads.The sensor assembly is waterproof and insulated for 600 V CAT IV; 1000 V CAT III. The AmpFlex® meets EN 61010-1, is CE marked, and is designed with materials and components to meet international agency standards.The AmpFlex® has an mV output proportional to the current measured fordirect readings on DMMs, data loggers, oscilloscopes, and power or harmonic meters. TRMS measurements are taken when connected to a TRMS meter.The AmpFlex® is insensitive to DC currents and only the AC component of the measured signal is measured.The length of the flexible sensor can be selected in lengthsof 24 in, 36 in, and 48 in lengths. Consult the factory for custom lengths, ranges and/or features.2.2 AMPFLEX®Figure 11.Positive: Red Banana Plug (+).mon: Black Banana Plug (-).3.Power ON Indicator (Green LED).4.Overload Indicator (Red LED).5.Range Selection Switch.6.AmpFlex® Connector/Latch.7.Flexible Sensor (Diameter 0.5 in, 12.5 mm).8.Lead from Sensor to Module (6.5 ft, 2 m).9.Electronic Module - Descriptive Label on Back Case (range, model, etc.)2.3 FEATURES■Models to measure from 0.5 A rms to 30,000 A rms.■Accuracy: 1 % of reading.■TRMS measurements when connected to a TRMS instrument.■No core saturation or damage if overloaded.■Overrange LED for measurement circuitry.■600 V CAT IV; 1000V CAT III; EN 61010; CE Mark.■Waterproof sensor.■9 V battery for typical 150 h continuous operation.■Shape Memory for custom pre-shaping of sensor before use (no drooping).■Very high frequency response.■Low phase shift for power.■Insensitive to DC, measures only AC component on DC + AC signals.■Excellent linearity.■Lightweight.2.4 ACCESSORIESBanana (Female) / BNC (Male) Adapter ........................................Cat. # 2118.46 For connection of the AmpFlex® to SLII Models L101, L102, L562,BNC terminals on scopes and other displaying instruments.2.5 STANDARD MODELSAll AmpFlex® models are designed to be used with recorders or power analyzers with a voltage AC input.

OPERATIONPlease ensure that you have already read and fully understand the Precautions for Use section on page 6.3.1 MAKING MEASUREMENTS WITH THE AMPFLEX®■Connect the electronic module to the AC Volt range of your Digital Multi-Meter (DMM)or measuring instrument. Select the appropriate module output voltage range. If the current magnitude is unknown, and if AmpFlex® has two ranges, select the lowest mV/A output setting.■Wrap the flexible core around the conductor to be tested. If possible within range, select the higher mV/A AmpFlex® output range to obtain the best resolution. Do not exceed specified current range for the output. Do not use on selected range if overload LED goes on.■Read the displayed value on the DMM and divide it by the range selected (i.e. if reading = 2.59 V with the 10 mV/A output range, the current flowing through the probe is 2590 mV ÷ 10 = 259 A).■For best accuracy, carefully center the conductor inside the flexible core, and avoid if possible, the proximity of other conductors which may create noise and interference (particularly near the latch).■True RMS measurements are obtained when the AmpFlex® is connected to a True RMS meter. Note that the DC component is not measured.3.2 TIPS FOR MAKING PRECISE MEASUREMENTS■When using the AmpFlex® with a meter, it is important to select the range that provides the best resolution. Failure to do this may result in measurement errors.■For best results, select the highest AmpFlex® output signal possible and the most sensitive meter range for this output.■Make sure the DMM or measuring instrument can accurately measuremV AC. Certain inexpensive DMM have poor resolution and accuracy when measuring low mV AC.■For best accuracy, center the AmpFlex® around the conductor to be measured (see figure 2).■To increase sensitivity or measure on low currents, the AmpFlex® may be wrapped several times around the conductor. Divide your reading by the number of turns for the actual measurement (see Figure 4).■The overall measurement accuracy is the sum of the AmpFlex® accuracy and the displaying instrument accuracy.For best accuracy, center the AmpFlex®Figure 2■The AmpFlex® may be doubled around the conductor to be measured to double the output (see Figures 3 and 4 to show the different values on a DMM while measuring 250 A ac).One turn around a conductor carrying 250 A ACFigure 3Double the turns to double the output in low-current applications or for higher sensitivity.Figure 43.3 TYPICAL RESPONSE CURVES1 Hz10 Hz100 Hz 1000 Hz 10 kHz 100 kHzTypical Accuracy % vs. Frequency @ 100 A, 1 mV/A OutputFrequency1 Hz10 Hz100 Hz1000 Hz10 kHz 100 kHzTypical Accuracy % vs. Frequency @ 100 A, 10 mV/AFrequency%± 10± 9± 8± 7± 6± 5± 4± 3± 2± 1± 0Typical Accuracy % per Range to 100 AAmps3000 A 2500 A 2000 A1500 A 1000 A 500 A 0 A1000 Hz10 kHz100 kHzCurrent Derating Curve (I < 3000 A)FrequencyA m p s100 Hz1000 Hz10 kHz 100 kHzCurrent Derating Curve (I > 3000 A)FrequencyA m p s1 Hz10 Hz100 Hz1000 Hz10 kHz100 kHzTypical Phase Shift vs. Frequency @ 200 A, 1 mV/A OutputFrequencyD e g r e e s4.

漏电流测试仪使用说明书(总10页)--本页仅作为文档封面，使用时请直接删除即可----内页可以根据需求调整合适字体及大小--漏电流测试仪使用说明书一、操作说明使用本仪器之前建议用户阅读一下本技术说明书，了解熟悉本仪器的使用方法和工作原理。
仪器在接通电源之前，应将电压调节旋钮向左旋至最小，工作选择按钮置于放电位置，否则电压输出接线柱与外壳间有极化电压输出，会使连接测试夹具时触电。
在使用仪器过程中，转换电压量程开关时，注意要将电压调节旋钮向左旋至最小，以免电压表受冲击而损坏。
１、面板上各器件之功能说明（１）右下角的电源开关按至ON位置即接通电源，此时相邻的绿色指示灯即有亮的指示。
（２）中间的电压调节旋钮是控制施加在被测电容器上的直流极化电压数值的，可以从电压表显示器上显示出来，其范围由其左边的电压量程开关决定。
其中TH2685C量程为0 ～50V/0 ～200V，TH2686C量程为0 ～200V/0 ～500V，TH2687C量程为0 ～200V/0～650V，TH2688C量程为0 ～25V/0～75V。
（３）右上的时控开关及时间拨盘是控制仪器内线路从充电自动转换至测试状态的延时时间，当时控开关处于OFF时，其时间拨盘不起作用，时间显示器无显示，此时测量即为手控测试。
当时控开关处于ON时，充电时间的计算是从被测电容器接上仪器进行充电的瞬间就自动算起的，面板右上的充电指示灯（黄色）是指示充电时间的。
时间显示窗口显示被测电容器充电时间的倒记数时间值，当时间窗口倒记数显示为０时，充电指示灯熄灭，仪器进入测试状态。
（４）右侧中间的置限开关及置限电位器是由于被测电容器漏电流分选而设置的，在正常测试时，置限开关处于OFF位置，当置限开关处于ON时，仪器则处于门限预置状态，此时仪器夹具上不应有任何被测元件，电流表指示出其预置电流值，结合电流量程开关，调节预置电流旋钮，将电流表的指针调到需要的预置数值上，以后在测试过程中，遇有漏电流超过这个门限值的，仪器的蜂鸣器立即鸣响，左边的不良指示灯即亮，以示超差。

武汉华能阳光电气有限公司配电网电容电流测量仪资料书一、用途及特点配电网的对地电容和PT的参数配合会产生对地电容值。
传统的测量配网电容电流的方法有单相金属接地的直接法、外加电容间接测量法等，这些方法都要接触到一次设备，因而存在试验危险、操作繁杂，工作效率低等缺点。
本仪器适用配网电压等级：6kV、10kV和35kV中压配电网中性点不接地系统中性点一般是不直接接地的，所以当线路单相接地时流过故障点的电流实际是线路对地电容电容电流进行测量以做决定。
本测试仪直接从PT的二次侧测量配电网统的测试方法相比，该仪器无需和一次侧打交道，因而不存在试验于从100V的交流电障发生，亦不会损坏PT和测试仪，因而无需做特别的安变得安全、简单、快捷，且测试结果准确、稳定、可靠。
该测试仪采用大屏幕液晶显示，中文菜单，操作非常简便，且体积小、重量轻，便于携带进行户外作业，接线简单，测试速度快，数据准确性高，大大减轻了试验人员的劳动强度，提高了工作效率。
