6-22 G30 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUALMETERING CHAPTER 6: ACTUAL VALUES6The harmonics are a percentage of the fundamental signal obtained as a ratio of harmonic amplitude to fundamentalamplitude multiplied by 100%. The total harmonic distortion (THD) is the ratio of the total harmonic content to thefundamental:Eq. 6-46.4.4 SynchrocheckACTUAL VALUES METERING SYNCHROCHECK SYNCHROCHECK 1(4)If synchrocheck or a setting is "Disabled," the corresponding actual values menu item does not display.6.4.5 Tracking frequencyACTUAL VALUES METERING TRACKING FREQUENCYThe tracking frequency displays here. The frequency is tracked based on the selection of the reference source with theFREQUENCY AND PHASE REFERENCE setting in the SETTINGS SYSTEM SETUP POWER SYSTEM menu. See the PowerSystem section of chapter 5 for details.Voltage harmonics are calculated only for Wye connected phase VTs. Ensure that the SYSTEM SETUP AC INPUTS VOLTAGE BANK F5 PHASE VT XX CONNECTION setting is “Wye” to enable voltage harmonics metering.
