Advanced 30/50/80/120 KV Ultra-low Frequency AC High Voltage Tester VLF Cable AC Test Equipment
What is a Very Low Frequency Withstand Test?
A Very Low Frequency (VLF) Withstand Test is an AC Withstand Test usually carried out at a frequency between 0.1 Hz and 0.01 Hz. This kind of test is suited for testing high capacitance loads such as cable and rotating machinery. This is a pass fail test i.e. bad cable will fail during testing rather than in service.

Advanced 30/50/80/120 KV Ultra-low Frequency AC High Voltage Tester VLF Cable AC Test Equipment Introduction
Ø VLF Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.
Ø 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.
Ø It can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment
