transformer 3 ph, 225 kva pri 480v, sec 208v. primary
neutral connected to system, is secondary neutral to be
grounded and how
What will happen if we on 200kvr capacitor bank(11kv in bus)If there is low load on transformer (1.5 mva 33/11 kv)
what happen if generator of micro hydro running at only a small percentage of its capacity, as a comparison, if the diesel generator that runs on only a fraction of its capacity there will be a wet stacking
In a 3 phase 4-wire system. For a 3.5 core cable if all loads are single phase and balanced, what will be neutral current? will it be sum of all phase currents? Or it will be zero? And if loads are unbalanced what will be neutral current?
difference between isolater and circuit breaker?
IF we want to replace I/C bay at our 220 kv substation which is of 140 mw load capacity bay to be replaced by 400 mw capacity bay.other than CT(1200/1) what are the other equipment i have to replace.
why there is a phase shift lies between primary and secondary voltages of a transformer?
Why breakers not synchronized when the synchroscope is going in the anticlockwise direction?
what is the difference between 230v and 115v?
