Performance Overview: The transformer comprehensive testing bench conforms to international standards. It is primarily designed to test the load and no-load characteristics of power operating or distributing transformers. Additional testing capabilities include power frequency withstand voltage, induced withstand voltage, temperature rising, partial discharge, and turn ratio programs.
The system utilizes an advanced single-chip microcomputer for synchronized data sampling, effectively eliminating errors common in manual reading of voltage, current, and power.
