Battery is a voltage source? give one example of current source and why?521
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.576
For DG or Transformer body earthing, is it necessary to terminate the earth bus to earth pit directly? If not terminated to earth pit directly in earth pit and connected to any common bus strip which ultimately connects to earth pit, what will be the pros and cons?1 712
