1 2701what reason of line current and phase current in star connection and line current and phase current not equal in delta connection?
1570What will be the capacity of the generator set which can be used for my 2 ton window air conditioner ?
1 2760As we know induction squirrel cage motor torque Directly praprortinal to applied voltage in star connection & delta also. If I connect 55KW Motor to DOL starter in load condition does motor withstand the load & what will be the current withdrawn ? motor will not fail ?
1392To determine the Healthiness of Insulation we will be performing Dielectric tests i.e Insulation Resistance test, Partial Discharge test,Switching Impulse, Lightning impulse, Tan Delta test ...etc why we required to perform this many test, why cant we do only one test. for Transformer, CT's
1 2891The armature of shunt dc motor has 0.8ohm resistance and motor is to run on 120V circuit.If motor is suddenly thrown on circuit while armature at standstill then current drawn by motor will be??Also back emf in normal running is 110V
2 5547If a shunt Dynamo has induced emf 100V and 0.4 ohm resistance and battery of accumulator of open circuit emf 110V and 0.5 Ohm resistance are in parallel what is common terminal potential difference?

The sodium vapor lamp is not glows when it is connected a distance of 5 meters above from gearbox, why ?
Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.???? My Whats app No:07621840498 for Further Discussion. Pls experts suggest.
how is the incoming cable size calculated for a given current rating of a panel??
prove that power consumed in 3 phase delta system is 3 times as compared to 3 phase star system
An impedance of 100 ohms resistance and an unknown inductance is connected across the capacitor. The resulting impedance is a pure resistance of 500 ohms ifω = 10^5 rad/sec. calculate the values of inductor and capacitor.

hi there i am highly enthusiastic about discussing electrical concepts , and hence i wud lyk to invit al do intrested to join me at gtalk and hav a dscussun of the concepts , ad me as a freind . my email id is rakesh.2k99@gmail.com
what is the difference between 50 hz freq. and 60 hz freq.? which is better and economic in them ?
I Need standard operation procedure(SOP)for 500kva Oil type transformer oil filtration & Procedure for IR value checking.
Why should be the frequency 50 hz 60hz only why not others like 45, 95 56 or anything , why should we maintain the frequency constant if so why it is only 50 hz 60hz?
Does magnetomonopoles exists? one maxwell equation strongly suggests no, but how about their existance in plasma?
