Oil ImmersedPotentialTransformer(Inductive Voltage Transformer)shall be suitable for measurement control and relay protection in the outdoor AC power system of nominal voltage 36~500kV, and frequency of 50 or 60Hz.

Oil Immersed Potential Transformer(Inductive Voltage Transformer) shall be suitable for measurement control and relay protection in the outdoor AC power system of nominal voltage 36~500kV, and frequency of 50 or 60Hz.

Inductive instrument transformer of JDX- series shall be suitable for measurement control and relay protection in the outdoor AC power system of nominal voltage 36~550kV, and frequency of 50 or 60Hz, this type voltage transformers are oil immersed electromagnetic voltage transformer. The core was used cold-rolled silicon steel strip to folded single-column and three pairs of the same potential with the ground. High voltage coil main insulation chose sheet paper, small oil clearance and large structures. It was wounded as pagoda-shaped segments. High-voltage leads were insulated by a condenser bushing. We select corrugated metal expander as oil temperature variation compensator and can inspect the oil level through window. Fuel tank and the lower tank welded together, and all the other seals are made of sealed limit, effectively preventing the leakage of oil.
