why the electric train touches only one conductor n where is the neutral n it will be running 3-phase or 1-phase?
3 7017what are the oils used in transformers cooling? n which type transformer is used in power systems?
1 4447the electric traction poles having 3 cables n two cables touches with a insulator (or any) another one separated but it will be running 1-phase why?
4 6052what are check points to be checked while charging switchyard?(CT,PT,BREAKER,POWER TRANSFORMER)
1 5555hello everybody. please tell me the function of transformer bushing,s. i heared somewhere that it saved transformer winding from sky electricity. please tell me if that is right then how it work,s. Thank,s.
3EEE,
2 5472When we synchronize the Generator BKR with TIE BKR then Gen BKR is hold but TIE BKR is Tripped on Non directional over current but when TIE BKR is Syn. with Gen. BKR then no fault occur so what is the problem

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.

1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
