I have 4 DG set with 1500KVA rating. system breakers are 11KV & alternator are 415 Volts. i want to Know what is max. resistance for body earthing & 415 & 11KV V Neuteal earthing. my fault current is 14 times for 2 sec.

5 23789I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed. The manufacturer suggested changing the capacitor which made no sense, but I did it to no avail. Could this possibly be caused by the centrifugal switch intermittently reconnecting the start winding?
1 2770I have 4 DG set with 1500KVA rating. system breakers are 11KV & alternator are 415 Volts. Between alternator & breaker one stepup transformer used. i want to Know what is max. resistance for body earthing & 415 & 11KV V Neuteal earthing. my fault current is 14 times for 2 sec.
1843Power factor =1.000 at factory in supply. However, PF = 0.8 at motor end. Current = 100 Amp, Voltage = 400 V. What is the power distribution loss? Can I reduce it by adding capacitor at the load feeder?

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.
