What will be the effect of in HT XLPE 220 KV cable when one side of the Armour/cable ends are not grounded. Will there is difference between 3-phase voltages? like: if A. Both End of Cable grounded Phase Voltages:- V1=219 KV, v2=220 Kv, v3=220 KV. B. One End is grounded other is not: than Impact on Phase Voltages:- V1= KV, v2= Kv, v3= KV. Remain same or unchanged??

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
