The HZBD-IV is a fast-testing, high-precision multifunction transformer turn ratio tester designed for comprehensive power transformer diagnostics. In a power system, the transformer is a core component, and its long-term reliable operation is crucial for the stability and reliability of the entire system.
This instrument features fully intelligent one-touch testing for DC resistance and turns ratio. Based on the set testing parameters, it intelligently identifies the current tap position of the transformer, automatically tests and saves the turns ratio and DC resistance data for that tap position.
