Product Introduction

HCR1000 Transformer Winding Deformation Tester (Frequency Response Method) is used to test power transformers with voltage levels of 6kV and above and other transformers for special purposes. Power transformers are inevitably subject to various fault short-circuit current shocks or physical impacts during operation or transportation. Under the strong electric force generated by the short-circuit current, the transformer winding may lose stability, resulting in permanent deformation such as local distortion, bulging or displacement, which will seriously affect the safe operation of the transformer.

Functional characteristics

The test can be carried out without covering or disassembling the transformer;

The currently popular sweep frequency method is used for measurement;

This instrument can measure transformers above 6kV;

The split structure is adopted, and the test host and the main control computer are connected by USB, which is plug-and-play;

The on-site wiring is simple and easy to use;

The measurement dynamic range is wide: -100dB~20dB;

The analysis software is powerful, and the software and hardware indicators meet the national standard DL/T911-2004.
