Introduction
The low voltage short-circuit impedance test is a direct method to check if a transformer winding is deformed due to short-circuit current or mechanical force. It is crucial for determining if the transformer can operate safely and if disassembly inspection is needed. Our SGZK-II Transformer Short Circuit Impedance Tester is designed for on-site and lab testing of low voltage short-circuit impedance in transformers rated 35KV and above.
