Answer Posted / abhishek-gaur
in DELTA connection, phase voltage = line voltage
in STAR connection, phase voltage = 1/(root3) times line
voltage
to reduce losses, transmtng voltag should be higher, so we
use delta connectn.
bcoz star connctn wil reduce phase voltg to 0.707 times line
voltg...
thus voltg is lowered wid star ... and losses incresed
compard to delta

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.
if we apply 1000ADC instead of 100ADC or We apply 50ADC instead of 100ADC,What will be happened in the test result value.Pl explain
