what is the difference between the characteristics of two different phase bushing of any transformer
NIT,
1331If 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?

1 2070what is the reason the main breaker is trip during the motor is running? (some time the breaker is not trip)
1295What if high voltage side circuit breaker of a ehv transformer instead of lvcb? Kindly elaborate.
1313at 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.

Help need in transformer !? Hello Friends The parameters of 2300/230 v 50hz t/f is R1=0.286 ohm R`2=0.319 ohm Rc=240 ohm X1=0.73 ohm X`2=0.73 ohm Xm=49.2 ohm Secondary Load impedance ZL=0.387+J0.29 solve the exact equivalent circuit with normal voltage across primery.. I know every thing but i cant find CURRENT I1=? and I`2=? Please help me give solution or only Formula please please...
