how does relay works?
wat s reactive power.... how could it be compensated.....
why stay insulator is not used with stay wire for 11kv Lines. Whereas it is used for LT lines ?

A 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?
can we run all LT motors at 360 volts which are normally rated 415+/-10% voltage rating
how to find 5 kilo meter long under ground 33 kv cable fault location if IR VALUE shows 0.05 M ohm @5000 volt.and cable fault locator shows some time fault distance 3 kilo meter ,3.7 kilo meter and some time 1 kilo meter? now how to find the fault location that where is leakage.
A simple Question from all.... If Voltage drops then its rated value what will be effect on a Residential load? similarly if voltage rises from its rated value then what will be effects on a load? i know if voltage drops the equipment or device draws more current then its rated what are other reasons ? thanks in advance for ur time.......
what are the compensations considered while designing a transmmision line.
What is C-factor?why it is required to consider in fault short circuit calculations?
Why Power factor is different - different in all three phase of a 3 phase nduction motor.
How reverse power relay sense the power is reverse in the system.
