China 80kv Vlf Very Low Frequency AC Hipot Tester for 35kv Power Cable, Find details about China AC Hipot Tester, Vlf Hipot Tester from 80kv Vlf Very Low Frequency AC Hipot Tester for 35kv Power Cable
VLF Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.
Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test. It is much smaller, lighter and portable than power frequency withstand voltage tester. It is proved home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.
It can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment
