Overview
The on load tap changer is a moving component connected to the transformer circuit, so the detection of on load tap changers is becoming increasingly important. In the "Regulations for Handover and Preventive Testing of Power Equipment", it is required to check the sequence of action of on load tap changers, measure switching time, etc. This transformer on load switch tester is mainly used to measure the transition waveform, transition time, instantaneous transition resistance value, three-phase synchronicity, etc. of the transformer on load tap changer.

Product Introduction
The on load tap changer is a moving component connected to the transformer circuit, so the detection of on load tap changers is becoming increasingly important. In the "Regulations for Handover and Preventive Testing of Power Equipment", it is required to check the sequence of action of on load tap changers, measure switching time, etc. thisTransformer on load switch testerIt is mainly used to measure the transition waveform, transition time, instantaneous transition resistance values, three-phase synchronicity, etc. of on load tap changers in transformers.
Transformer on load switch testerHighly intelligent, with all Chinese menu prompts and simple operation. The instrument has a small size, light weight, and strong anti-interference ability, greatly reducing the labor intensity of on-site workers. It is an ideal instrument for power generation and supply units, transformer manufacturing industry to ensure safety production and improve product quality.
