摘要
介绍了超低频技术的相关内容,并与直流耐压试验比较,指出过高的直流电场会对电缆带来不必要的进一步损伤,从而说明超低频技术是进行耐压试验的最佳技术。
The related contents of ultra-low frequency technique were presented.Voltage tests by the ultra-low frequency technique were compared with DC voltage tests.It thought that high DC electric field would damage cables and the ultra-low frequency technique was the best technique for the voltage tests.
