A separately excited dc motor having 2 ohm armature
resistsance draws a current of 10A and torque developed is
20 Nm under rated field condtion. the speed of the motor
under the rated field condtion , when it is connected to a
100V DC source and delivering 10Nm torque....
What should be the Sandwitch type Al. bus bar capacity for
2 M.W.Gen. set, having continuous full load current- 3463
Amps,ambient temp.- 50 Deg. C., Required temp. raise-20
deg.C., it will run 24 hrs, 365 days on full load, required
our industries ht line so power fluctation(once drop of
power please rectify causes
The power factor of the fixed load is 0.8, now the p.f is
varying from 0.8 to 0.5.
What should be the length of transmission line so that we
can see/obtain the full sine wave of voltage??
take 100kva DTR( delta/wye ), what ll happen if we connect
11kv to LT side instead of connecting to HT side? will the DTR
behave as a step up transformer or something else????
does buccholz in a transformer use batteries
why booster transformer is used in sumpners test conducted on
comparision between ACB and VCB
what is the earth current,reverse power,electrical trip
generator short circuit,low voltage, high voltage please
what is the question paper model for section engineer in RRB
in shunt clippers why a resistor is used in sereis with the
block diagram of 2 ups system connected in parallel mode?
why we use two slope(differential & restraining) in
differential relay.but in busbar protection differential we
are using only one slope?please explain
how does the terminal voltage of transmission lines increase
when a capacitor is connected???? This happens not only in
transmission lines but also in all circuits. How???
When a capacitor is connected in a transmission line,
capacitor also takes energy from the same supply. But how is
it able to increase the terminal voltage??? Practically What
sequence of events happen during increase in voltage???
The 3 phase 400 hp 440 volt slip ring induction motor do not take one phase
amps why ? The motor is running good condition
