|Can Superposition theorem be applied to AC Circuits?Can
Thevenin's Theorem be applied to AC Circuit too?
|why power factor is only cosine angle not sine angle?
|what is principle operation of transformer?
|Can a dc motor works as a dc generator. If yes , then how?
|why Line voltage =1.732XPhase voltage
what mean by 1.732
|can I connect step down transformer(25KvA,240V Phase to
phase)to output of online UPS(15KvA,440V PHASE TO PHASE)
Load connect to TRANSFORMER is 13KvA,240V PHASE TO PHASE.
please brief if it is wrong
|How transformer neutralshould earthed ? Transformer neutral
connected to earth mat in substations, right or wrong ?
|will three phase energy meter run without one phase
|what are the main parts of UPS what is the function of that?
|How does frequency affect KVA rating of a transformer?
If a 500 kva, 400 v, 60 hz t/f is to be operated on 50 hz
frequency then how will its KVA rating change?
Also explain why do u think like that.
