In a power system, the transformer is a core component, and its long-term reliable operation is crucial to the stability and reliability of the entire system. The HZBD-IV Transformer Characteristic Comprehensive Tester is designed with fully intelligent one-touch testing functions for DC resistance and turns ratio testing. Based on the set testing parameters, it intelligently identifies the current tap position of the transformer, then automatically tests and saves the turns ratio and DC resistance data for that tap position.
