Product Description

20kVA/100kV AC Withstand Voltage Test System

The 20kVA/100kV AC Withstand Voltage Test System is used to determine whether the insulation of electrical apparatus can tolerate the specified AC test voltage. The 100kV configuration provides a high-voltage testing source for manufacturers and technical organizations working with transformers, switchgear, instrument transformers, and other insulation components.

An Oil Type Test Transformer forms the high-voltage section of the equipment, while a Manual Control Console is used to operate the test and adjust the applied voltage. This arrangement provides a conventional solution for AC voltage withstand inspection, particularly where operators need direct control over the voltage rise and testing sequence.

FAQ

Q1: Can this system test both transformers and switchgear?

A: Yes. It can be used for compatible transformers, switchgear, CT/PT, insulation components, and other electrical apparatus.

Q2: What is the control method?

A: The system uses a manual operation console with manual voltage regulation.

Q3: Why is the test transformer oil immersed?

A: Oil provides the required insulation medium and helps dissipate heat from the transformer during operation.

Q4: Is this system suitable for high-capacitance cables?

A: The suitability depends on the cable length and capacitance. For long cables with high capacitance, an AC series resonant test system is generally a better choice.
