“…Rather than connecting a decoupling capacitor to the motor power cable, a stripped coaxial cable is used as a sensor to gather the PD signal under PWM excitation in [56,57]. The inner conductor of this cable sensor is placed on the sheath of the high voltage cable, which is connected to the twisted pair (to simulate motor winding).…”

Variable speed drives (VSDs) are widely utilized to control motors such as pumps, compressors, fans, etc. However, the endurance of motor winding insulation under repetitive voltage pulse excitation is weakened, resulting in premature failure and shortening the expected operating life. This article reviews the literature of investigations spanning the last two decades on the problem. Researchers have focused on different aspects to explain this from a particular angle. The precise mechanism is complicated as a number of interacting factors contribute to premature insulation failure. Insulation degradation in motors can be attributed to thermal, mechanical, chemical, and electrical stress. It seems that space charge accumulation and partial discharge (PD) are the two main influences; the former can exacerbate the electric stress distribution whilst the latter promotes insulation deterioration.

“…To analyze PD characteristics, IEC/TS 61934:2024 introduces PD measurement under impulse voltage excitation [57]. It focuses on the PD directly generated by the repetitive pulse voltage source without any filtering, this situation is also known as the worst-case PD detection.…”
