Rated voltage: 650kV (325kV/stage, two stages serial connection)
Rated current: 10A  Rated frequency: 50Hz
Partial discharge level: <2pC under 100% rated voltage when doing delivery test in our HV laboratory. But this value will be affected by outdoor interference. The partial discharge level will be about 50-100pC (Measured on-site after mounting).
Output voltage waveform deviation: ≤1.5%
Max. capacitance of test object: meet above load table requirement.
System minimum inductance: 125H  Maximum inductance: 3000H
Over-current capability: working 600s under 110% IH, no damage to reactor winding .
Over-voltage capability: working 60s under 110% UH(700kV), no damage to reactor insulation.
We have successful supplied 2250kV 2A outdoor use test transformer, we can make sure the system external insulation can meet the test requirement under the condition of outdoor use (At 650kV, maximum voltage 700kV) . The below picture is one module of our 2250kV test transformer. Its dimension is 3500mm (Dia) * 7200mm (H), equips with epoxy skirt. System function will not be affected by raining, snow or else.

Structure:
Internal structure:
①. 30-Q-130 Grain-Oriented Electrical Steel,
②. There are earthing baffle between winding and iron coil, the earthing is reliable.
③. We do many improment on the system; abandon some unreasonable structure and creat our new resonant. New variable inductance power frequency resonant reactor’s working life not less than 60 years.
④. The iron steel has been done the chip removing treatment. And then form a entirety with curing agent, which lower the noise; equip guide rail between adjustable iron coil and fixed iron coil, to make sure the iron coil move vertical or horizontal. We have been leader of the power frequency variable resonant system, moreover, we cooperate with famous university and research institute and improve our quality continuously.
