how to calculate the earthing conductor & no. of earth pits
required
Answer Posted / mrutyunjay
Dear Sudhakar Sir,
Greetings of the day !
Recently I have been through one answer shared by you and got your email id at AllInterview.com. Please kindly help me in my below concern :
Permissible current density equation i = (7.57*1000) / sqrt(resistivity * duration of earth fault) as per IS 3043
Is this equation to be taken for all types of electrodes ( Plate, Rod or Pipe & Strip ) ?
Because , as per IS 3043, same equation is appropriate for plate electrode
Is This Answer Correct ? | 1 Yes | 0 No |
