1.we cant measure directly very high voltages(in kv) in
switchyard.so we need to step down the voltage in kv into
some small values.so we can measure small voltages using our
meters.the purpose of using capacitor is to filter DC and
will allow AC only.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
