My energy meter ratio is -/110/root 3,1A and connected line CT is 100/1,PT is 11kv/110 so what is the MF for meter
1 5932A 60w bulb & a room heater are connected in series.if 60 w bulb is replaced by 100w then what will be the effect on heater out & why?
6 16607How will A Medium voltage circuit breaker(11 kV voltage level) operate under short circuit fault condition whether It is having short circuit release like Low voltage circuit breaker or relay should be given?
1944During 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.
1945how the CT and PT is connected in the circuit during testing of transformer explain with diagram
