※ purpose

　　It is mainly used to test the insulation level and partial discharge level of various insulating materials, insulating structures, electricians and power products to withstand power frequency voltage. It is widely used in electrical manufacturing departments, power operation departments, scientific research institutions and colleges and universities.

　　※ performance

　　50-1800kv non partial discharge power frequency test transformer has passed the signing of two parts. The dirty transformer and support transformer are mainly used in Sino foreign joint venture power transformer manufacturers. The main technical performance is in the leading position in China and reaches the advanced level of similar products in the world.

　　※ features

　　The complete set of equipment has strong configurability, complete voltage capacity series and perfect functions

　　The epoxy insulating cylinder without partial discharge is successfully developed to ensure that the partial discharge of the system equipment is small, which is better than that of peer enterprises;

　　High quality dq130-30 grain oriented silicon steel sheet and 45 ° fully inclined seam lamination are adopted. The waveform distortion rate and no-load current of the product are the lowest in China;

　　Low impedance voltage, better than international regulations;

　　It adopts automatic control technology and computer (optical fiber) measurement and control, with high degree of automation and strong anti-interference ability;

　　It adopts fast power protection device with high reliability

　　Ydtw type power frequency test transformer without partial discharge
