why rotor winding in induction motor is not earthed.
normally we uses star winding in rotor .why?
Answer Posted / sugun_eee
In Induction motor rotor, each phase winding will be
identical and equivalent in parameters. Hence for balance
star connection there will not be any(circulating) nuetral
current at star point. there by............

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.
