what is the difference between the characteristics of two different phase bushing of any transformer
NIT,
1 1884If a HV Underground Cable (13.8KV) is layed in the ground below 1.5 Mtrs and any building construction is done on the Cable route. IS this allowable or Not? What should be the clearance. As per ISO construction on HV cable route is safe or Not? Why? Can any body suggest the site for my question?
ZCL,
1 2955what is the reason the main breaker is trip during the motor is running? (some time the breaker is not trip)
1 1851What if high voltage side circuit breaker of a ehv transformer instead of lvcb? Kindly elaborate.
1 1840at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.

What is the height of DA, DAL, DB, DC & DDE tower?
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.
