VLF Hipot Test High Voltage AC Cable Hipot Tester

Why do we need to use High Voltage AC Cable Hipot Tester?
The High Voltage AC Cable Hipot Tester is a necessary tool to ensure the safety and reliability of high voltage cables before they are put into service. Here are some reasons why we need to use it:

Insulation testing: The tester applies a high voltage AC signal to the cable under test, which stresses its insulation and helps determine whether or not there are faults in the insulation. This type of testing ensures that the cable can operate safely and reliably at its rated voltage.


Quality control: Using the tester during production ensures that all high voltage cables meet the required international standards for safety and performance. This reduces the risk of customer complaints and costly product recalls.


Maintenance and troubleshooting: When a cable fails, the tester can be used to pinpoint the location and extent of the fault, making it easier and quicker to repair the cable and restore power.


Safety: The tester includes various safety features to protect the operator and equipment during testing, such as interlocks, warning lights, and adjustable trip levels that can be set to automatically shut off the high voltage if the leakage current exceeds a certain threshold.

Working principle of High Voltage AC Cable Hipot Tester
 

The High Voltage AC Cable Hipot Tester is designed to test the insulation capabilities of high voltage cables. The tester works by applying a high voltage AC signal to the cable under test and measuring the leakage current.
During the test, the cable is connected between the high voltage output of the tester and ground. The tester applies a high voltage AC signal to the cable, typically at a frequency of 50 or 60 Hz. This voltage creates an electric field around the cable that stresses its insulation.
If the insulation is sound, very little current will flow through it, and the tester will read a low leakage current. If there is a fault in the cable's insulation, such as a crack or pinhole, current will flow through the fault, and the tester will read a higher leakage current.
The tester also includes various safety features to protect the operator and equipment during testing. These include interlocks, warning lights, and adjustable trip levels that can be set to automatically shut off the high voltage if the leakage current exceeds a certain threshold.
