Overview
The transformer on load switch tester is designed according to the high voltage testing equipment of the power industry standard of the People's Republic of China, and the general technical conditions DL/T 846.8-2017. It can meet the requirements of the "Regulations for Handover and Preventive Testing of Power Equipment", such as checking the action sequence of on load tap changers and measuring switching time. It can achieve accurate measurement of parameters such as transition time, transition waveform, transition resistance, and three-phase synchronicity of on load tap changers, making it an ideal device for testing on load tap changers. (If the user is a load switch for capacity adjustment, please inform in advance)
