Electrical Engineering · Electrical Earthing and Installations
According to Indian Standard (IS) codes, how should the combined electrode resistance be measured if multiple earthing electrodes are connected in parallel?
- 1Measure the total equivalent resistance of the combined system of electrodes in parallel.✓
- 2Measure individual electrode resistances separately and calculate the simple average.
- 3Use a clamp meter to measure individual values, then sum them up.
- 4Measure individual electrode resistances separately and add them together.
Correct answer
Measure the total equivalent resistance of the combined system of electrodes in parallel.
