In Fact VLF Test Is The Substitute For Power Frequency Test. It Is Suitable For Testing Electrical Equipment With Large Capacitance.
Small size and light weight. Big LCD screen and built-in printer.
0.1Hz, 0.05Hz and 0.02Hz can be chosen, which ensures a wide test range.
It realizes the fully automatic voltage boost, step-down, measurement and protection as well as the manual intervention in the process of automatic voltage boost.
Overvoltage protection and over-current protection. Action time is no longer than 20ms.
Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.
A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.
Closed-loop negative feedback circuit is adopted. No capacity rising during outputting.
