On load tap changer tester for transformers in Hangzhou and Suzhou

BYKC-IV typeTransformer on load tap changer testerIt is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of on load tap changers for power transformers and special transformers in power systems. It adopts computer control and can measure the transition time, transition waveform, transition resistance, three-phase synchronicity, and other parameters of the on load tap changer through a specially designed measurement circuit. Users can directly measure them through the tap changer leads according to their needs and site conditions, or directly connect them through the transformer three-phase bushing and neutral point for measurement.
