CHAPTER 6: ACTUAL VALUES RECORDSG30 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL 6-256Magnitudes of the third harmonic components of the machine neutral point voltage (VN), the zero-sequence voltage at themachine terminals (V0), and in the vector sum of the neutral point voltage and zero-sequence voltage (VN + V0) areavailable for display. The values are calculated for a signal source specified under the STATOR GROUND settings menu.These readings can be useful when selecting a pickup and supervision setting for the third harmonic neutral undervoltageprotection element.6.4.12 Volts per hertzACTUAL VALUES METERING VOLTS PER HERTZ 1(2)This menu displays the data for volts per hertz.6.4.13 Restricted ground faultACTUAL VALUES METERING RESTRICTED GROUND FAULT CURRENTS RESTRICTED GROUND FAULT 1(4)This menu displays the differential and restraint current values for the restricted ground fault element.6.4.14 Transducer inputs and outputsACTUAL VALUES METERING TRANSDUCER I/O DCMA INPUTS DCMA INPUT xxActual values for each DCmA input channel that is enabled are displayed with the top line as the programmed channel IDand the bottom line as the value followed by the programmed units.ACTUAL VALUES METERING TRANSDUCER I/O RTD INPUTS RTD INPUT xxActual values for each RTD input channel that is enabled are displayed with the top line as the programmed channel IDand the bottom line as the value.6.5 Records6.5.1 User-programmable fault reportsACTUAL VALUES RECORDS USER-PROGRAMMABLE FAULT REPORTS VOLTS PER HERTZ 1 VOLTS PER HERTZ 1:0.000 pu RESTRICTED GROUND FAULT 1 RGF 1 DIFF Igd:0.000 A RGF 1 RESTR Igr:0.000 A DCMA INPUT xx DCMA INPUT xx0.000 mA RTD INPUT xx RTD INPUT xx-50 °C USER-PROGRAMMABLE FAULT REPORTS NEWEST RECORDNUMBER: 0 LAST CLEARED DATE:2002/8/11 14:23:57
