Similarly, the "G" suffix denotes a "ground", hence a "51G" being a time overcurrent ground relay[4].Note 2: A suffix number may also be used with a device number: numbers are used to distinguish multiple "same" devices in the same equipment such as 51-1, 51-2.Note 3: Device numbers may be combined if the device provides multiple functions, such as the instantaneous/time-delay AC over current relay denoted as 50/51Note 4: For function descriptions, refer to IEEE standards reference library or American Standards C37. For understanding and learning application of these devices, many technical reference books have been published and are are available. These device numbers and their application are typically in the domain of electrical engineers, specifically power generation, transmission or distribution system engineers in regards to safely controlling and protecting users and equipment2 Time-Delay Starting Or Closing Relay8 Control Power Disconnecting Device12 Over-Speed Protection21 Distance Relay24 Over-Excitation (V/Hz)25 Synchronizing Or Synchronism Check Device26 Machine Field Overtemperature27 Undervoltage Device27 Machine Field Undervoltage Device27TN Third Harmonic Neutral Undervoltage30 Annunciator Relay, Multifunction Relays32 Directional Power Device37 Undercurrent Device,37 Machine Field Undercurrent Device38 Bearing Overtemperature40 Loss Of Field Or Excitation Device (Impedance)40Q Loss Of Field Or Excitation Device (Reactive Power)46 Reverse-Phase Or Phase-Balance Current Relay47 Phase-Sequence Voltage Relay48 Incomplete Sequence49 Stator Overtemperature49 Thermal Image Relay50/27 Inadvertent Generator Energization50 Instantaneous Overcurrent Or Rate-Of-Rise Relay51 AC Time Overcurrent Relay50/51 Instantaneous And Time Overcurrent Relay50/51(+) Overcurrent Relay51V Voltage Restraint Overcurrent Device50BF Breaker Failure Relay55 Power Factor Relay56 Field Application Device59 Overvoltage Relay59N Neutral Overvoltage Device60 Voltage Or Current Balance Relay61 Machine Split Phase Current Balance64 Ground Detector Relay64TN 100% Stator Ground Device66 Starts Per Hours67 AC Directional Overcurrent Relay67_2 Negative Sequence Directional Overcurrent68 Blocking Relay69 Circuit Breaker Supervision And Control Device74 Alarm Relay Multifunction Relays76 DC Overcurrent Relay78 Phase Angle MeasuringOr Out-Of-Step Protective Relay79 AC Reclosing Relay81 Frequency Relay81R Rate of Change of Frequency84 Transformer Tap Changer Control Device85 Carrier Or Pilot-Wire Receiver Relay86 Lockout Relay87 Differential Protective Relay87L Line Current Differential Relay L9087T Transformer Differential System87S Machine Stator Differential Protection System 87G Ground Differential or Restricted Ground Fault 87(+) Differential Relay94 Tripping Or Trip-Free Relay Multifunction Relays95 Reluctance Torque Synchrocheck SPM96 Autoloading Relay。
