WebThe relay shall test the earth return resistance prior to energising. After energising, the earth continuity device shall continuously monitor the earth resistance. A trip shall be initiated or the device shall not be energised if the resistance between a pilot core and earth falls below 1kΩ. The minimum operating time of the device shall be ... Web3. Earth Continuity Test. The earth continuity conductor, including metallic envelopes of cables and metal conduits, shall be tested for electric continuity. The electrical resistance of the circuit and the earthing lead is measured from the connection with the earth electrode to any point in the earth continuity conductor. This shall not ...
