Abstract |
|
In this work, a comparative study on the variation of maximum voltage to ground and voltage across the coils under different impulse voltages indicated that non-standard impulse voltage waveform develops higher voltage stress in the windings. They draw high risk and are critical to transformer insulation system. [1] Described method can be used by transformer manufactures to estimate voltage wave forms during switching or lightning, and to proves useful information for insulation coordination studies. [2]. |
