I want to let you know that their is thumb rule for insulation test.state as follow: insulation resistance test voltage=1kv, minimum expected=1megger ohm, 2kv = 2megger ohm, 5kv = 5 megger ohm etc. So your result is okay.

it is only the manufacturer of rectangular copper bar that can give you correct current rating of the copper.this because the purity of vary from one manufacturer to other but the approximate method of determining copper bar current rating is 2Ampere/mm sq(i.e 2x surface crossectional area of...

rdvette, i want you to understand that hipo test is use to ascertain that insulation level between phase to phase conductor or phase conductor to earth.so therefore same thumb rule that is applicable to insulation resistance test is applicable for this test.This thumb rule state that if you...

HI, The approximate short circuit current calculation of a hvdc cable is mathematically express as : (Kv)*(Kv), where Kv is hvdc voltage rating

Hi Azril, Base on my own working experience,the causes of reverse power in turbine generator can be attributed to: 1. improper position / incorrect polarity wiring of C.T in the generator or generator sychronization panel to reverse power relay( it happen in a...

Base on my experience it does not matter whether u use delta-delta or delta-star type of stepdown xformer but make sure ,either phase voltage or line voltage in both delta-star and delta-delta stepdown xformer respectively is thesame as operating voltage of electric motor.
