The on-load tap changer is the only moving part connected to the transformer circuit, therefore, its testing is receiving increasing attention. The "Power Equipment Acceptance and Preventive Testing Regulations" require checking the operating sequence of the on-load tap changer and measuring the switching time. This instrument is mainly used to measure the transition waveform, transition time, instantaneous transition resistance values, and three-phase synchronicity of the on-load tap changer of a transformer.
This instrument is highly intelligent, with full Chinese menu prompts, making it easy to operate. Its small size, light weight, and strong anti-interference capabilities greatly reduce the workload of on-site personnel, making it an ideal instrument for power generation and supply units and the transformer manufacturing industry to ensure safe production and improve product quality.
