|What is hysteresis losses?
|we all know that in transformer, voltage and current are
inversely related i.e. Vp/Vs= Is/Ip....so in standard
CT..we have a ratio of 200/5...that means our voltage
should increase by ratio of 40..althoug that is not the
case...because that requires high insulation level.and
pratically not feasible......can anybody clarify my
|How the Transformer oil testing is done & Why oil dielectric
goes LOW & what is solution for that ??
|why the motor is rated as kw& transformer as kva
|why D.C excitation is given to sunchronous motor?
|Why transformer neutral earthing? What is advantages?
|7. Why AC motors, AC bulbs etc... are donot operated by
DC signals? and
Why DC motors, DC bulbs etc... are donot operated by
|how we decide scurt (disc) of insulator
with respect to kv rating
|explain about RTCC
|can anyone tell me the website for star-delta control
|what is the use of earthing?
|explain why the secondary terminal of current transformer
should not be lift open circuited.
