Answer / ankit shukla

because VL is leading by 90 degree to VC

why the Parameters : Base Voltage & Maximum Voltage can't be equal in value in a VFD (Variable Frequency Drive) ? How much the base voltage would be lower than the maximum voltage ? If 400 V is the 3 phase output of a VFD ... then what should be the base voltage ? thanks a lot

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.
