|What will the effect on a motor designed at 60 HZ, and
operated on 50 HZ ??
|what is "pu" in electrical engg.
|why induction motor always operate at lagging p.f.?
|Why should The rating of 11 kV DO Fuse is in mulyiple of
hundred(200 Amp. 40 Amp, etc) Ampere wheareses the its
fuse elemnt has rating in just few Amp (< 12 Amp)? ( Is it
jusy beacuse of factor of safty).
|In how we connect watt meter for open & short circuit test
of a single phase transformer.
|Is there any calculation to find unknwon(unferroled) phases R Y B in alternator,3 phase motor anybody shoot my problem.
how can we notice this is the respective phase?
|What is Procedure the procedure to select CT's & PT's in
66kV and above substation?
|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 can we calculate the rating of a cable with formula?
|why DG neutral is earth?
|why power factor occur only inductive load not in resistive ?
|why an ideal voltage source has low internal resistance????
