Earthing shall generally be carried out in accordance with the requirements of Indian Electricity Rules 1956, as amended from time to time and the relevant regulations of the Electricity Supply Authority concerned. All medium voltage equipment shall be earthed by two separate and distinct connections with earth. In the case of high and extra high voltages, the neutral points shall be earthed by not less than two separate and distinct connec- tions with earth, each having its own electrode at the generating station or substation and may be earthed at any other point provided no interfer- ence is caused by such earthing. If necessary, the neutral may be earthed through a suitable impedance.
