Product Description

Transformer Winding Deformation Diagnostic Tester
Portable Sweep Frequency Response Analysis SFRA Analyzer

Application

 

1. During routine test of power transformer maintenance, check the frequency response data of transformer winding

2. When the power transformer leaves the factory, measure the winding frequency response data of the transformer as the characteristic fingerprint information of the transformer

3. After the power transformer is short-circuited, measure the frequency response data of the power transformer and compare it with the test data before the short-circuit to check whether the transformer windings are deformed.
