Product Description

VLF High Voltage Testing 0.01Hz 80kv Very Low Frequency AC Hipot Tester

VLF High Voltage Testing 0.01Hz 80kV Very Low Frequency AC Hipot 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.

VLF High Voltage Testing 0.01Hz 80kV Very Low Frequency AC Hipot Tester can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment.

Max voltage output: refer to table 1;

Output frequency: 0.1Hz, 0.05Hz, 0.02Hz;

Measurement accuracy: 2.5%;

Positive and negative voltage peak errors < 2.5%RDG+0.3%FS;

Controller of VLF AC Hipot Tester;

It with over voltage and over current protection;

Data of current, voltage and wave form can be directly sampled at high voltage side, so the data is real and accurate;

With color man-machine interface touch control plus controls modular software operating system, precise and intuitive;

Multi-purpose, can simultaneously measure tested objects capacitance, insulation resistance, leakage current, and AC withstand voltage test;

Full set of 80kV VLF AC Hipot Tester;

From left to right is: Controller, 30kV Booster, 50kV Booster, capacitor;

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;

High-voltage control part adopts innovative light control HV switching unit, control is accurate, safe and reliable
