摘要：
The dependence of partial discharge inception voltage (PDIV) and repetitive partial discharge inception voltage (RPDIV) on some voltage impulse parameters (impulse width, rise time and repetition frequency) is investigated in this paper focusing on crossed pair specimens made of polyimide-amide enameled wires. The results are explained in terms of partial discharge physics and provide basis to improve evaluation during both type and quality tests of random wound motors.
