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 6027A 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 16837How 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?
1995During 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 an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
