Building 6, Optics Valley Electromechanical Industrial Park, No. 84 Gaoxin 5th Road, Donghu New Technology Development Zone, Wuhan City, Hubei Province
UHV-3000 on load tap changer testerIt is designed according to the high voltage testing equipment of the power industry standards 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, measuring switching time, etc. 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)
Product nickname: On load tap changer tester, transformer on load tap changer tester, transformer on load switch tester
