Product Description

Hipot VLF 80kV High Voltage Very Low Frequency Hipot Tester

 

 

What does a VLF tester do?
 

 

A VLF (Very Low Frequency) tester is a specialized electrical testing device used to detect insulation defects, degradation, or contamination in high voltage equipment, such as transformers, cables, and other electrical systems. It operates at very low frequencies, typically between 0.1 Hz and 300 Hz, which allows it to penetrate deep into the insulation material and identify issues that may not be detectable with conventional high-frequency testing methods.

How does a VLF tester test?
 

The VLF tester works by applying a low-frequency AC voltage to the insulation system while monitoring the current flow and capacitance. By analyzing the changes in these parameters, the tester can detect potential problems, such as air pockets, moisture, or partial discharges, which could compromise the integrity and performance of the insulation. Early detection of these issues can help prevent equipment failure, reduce maintenance costs, and ensure the safe and reliable operation of electrical systems.
