power frequency withstand voltage test system

General Description of HV Test Transformer:

The power frequency voltage withstand test purpose is performed to examine the insulation strength and whether partial discharge occurs.

YDJ(G) AC test transformer is based on the Department of Electrica“test transformer”standard produced in the original basis of similar products after a lot of improvements,TDM(G) type AC-DC high voltage test transformer is YDJ(G) series of tests on the basis of the transformer in accordance with national standards“JB/T9641-1999”after improvements production of a new product.This series of products with small size,light weight,compact,full-featured,versatile and easy to use features. Espec -ially for power systems,industrial and mining enterprises, scientific research departments of various high-voltage electrical equipment, electrical components,insulation material insulation strength test frequency or DC high pressure.Is indispensable in high voltage test equipment.

What is the power frequency withstand voltage test of transformer?

Power frequency withstand voltage test is a test that must be done in the factory test of electrical equipment products. For example, circuit breakers, load switches, grounding switches, isolating switches, and switch cabinets must be tested before leaving the factory, and they must be fully tested. Meet the requirements. So what are the power frequency withstand voltage test standards for each level? The following summarizes the 1min power frequency withstand voltage (kV) effective values of some common voltage levels. Here, grounding switches and isolating switch products are taken as examples.

The factory power frequency withstand voltage of 10kV is 42kV
The factory power frequency withstand voltage of 35kV is 95kV
The factory power frequency withstand voltage of 110kV is 230kV
The factory power frequency withstand voltage of 220kV is 368kV
The factory power frequency withstand voltage of 330kV is 504kV
