Wuhan UHV specializes in producingseries resonance (also known as AC withstand voltage test equipment). Next, we will share with you the purpose of testing AC withstand voltage test equipment.

Purpose of series resonant AC withstand voltage test

Series resonant AC pressure testing is the most effective and direct method for identifying the insulation strength of power equipment. However, non-destructive tests such as insulation resistance and absorption ratio tests, dielectric loss TG δ tests, and direct current leakage current tests can detect some insulation technical defects. However, due to the low voltage level of these tests, some local control defects may not be reflected clearly, and these local defects pose information security risks during operation. In order to effectively identify local control defects in certain enterprises, it is necessary to conduct information exchange withstand voltage tests on the test samples.  

The AC withstand voltage test will make the existing insulation defects of the enterprise more obvious, and further reduce the insulation strength. The research on AC withstand voltage test is a destructive test, so we must adhere to the correct selection of test working voltage and withstand voltage time. Here, we recommend using the power frequency withstand voltage test device and the HTXZ series resonance test device to understand the AC withstand voltage test.
