Earthing System Health Assessment

Earthing System Health Assessment

The Process of Transferring the Immediate Discharge of The Electrical Energy Directly to The Earth by the Help of the Low Resistance Wire is Known as The Electrical Earthing. The Electrical Earthing is Done by Connecting the Non-current Carrying Part of the Equipment or Neutral of Supply System to the Ground.
