摘要：
The electric rotating machines have to meet the requirements in terms of safety, reliability and efficiency. This paper discusses the measurement dielectric spectroscopy of coils in asynchronous 6 kV driver before and after thermal ageing. Measurements for low frequencies were made by Isothermal Relaxation Current analysis, which is a non-destructive DC diagnostic measurement method for electrical machines. Measurements for high frequencies were made directly with LCR meter.
