GDVLF-80S High Voltage VLF AC Hipot Test Set for Cable Insulation Testing

Brief Description:

Withstand voltage test is an essential preventive test for electrical equipment. It is divided into two parts: AC and DC withstand voltage test. AC test can be further divided into power frequency, variable frequency and 0.1Hz very low frequency test, among which the last one is highly recommended by IEC, due to its remarkable advantages.
