using in R,Y& B PHASE LTSIDE(415V)ct ratio 4000/5 WITH ENERGYMETR OF 1280 REV./KWH,240V.WHAT WILL BE MF OF METRE.
what is DG A,B,C,D check?1 3014
a induction motar has 30-35% exciting current at no load but in transformer it is only 2-3% ofbrated current why any reason?1 2768
in short circuit. test of a transformer 5 to 10% ofvrated voltage is used why??? if we use rated voltafe then what will be?1 2341
in an open circuit. test there is no load curent.. but secondary. ia open then no urrent have to flow but there a smaller current flows why?4 4803
How i can select current transformer and meters for the upgrading the panal..for 200kw to 600kw....i need to select monitoring and protection ct,s and apmpire meter ,kw meter too.1 2725
Pl.brief me about Electrical power distribution system from Main generating station to Industry.What is the use of in between station.
which type of effect of turbine and generator reverse power protection ?
What is The Resistance Formula
how ct burden,magnetising current,ratio and knee point voltage are related & derived
what is the difference between linear choke and suction choke?

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
How to justify this statement ??? "Capacitors in series provide less capacitance but higher voltage breakdown rating for the combination"
