LVB-145/245 Mineral Oil Insulation Current Transformers

 

The current transformer is for the current measuring and protection for the power systems.

Rated voltage: 40.5kV~252 kV

Rated primary current: 50~4000A

Rated secondary current: 1A, 2A, 5A

Maximum output: 200VA(GB, IEC AS standards), or B-1.8, C200 (IEEE standard)

Rated frequency: 50Hz or 60Hz

The accuracy classes: 0.2S, 0.2, 0.5S, 0.5, 5P, 10P, PX, PR, TPY, TPZ (GB, IEC AS standards), or 0.15, 0.3, C (IEEE standard)

Partial discharge: <5pC

The bushing is made by porcelain

To avoid leakage, the aluminum alloy casted enclosure welded complete

Insulation material is mineral oil, low dielectric dissipation and low temperature-rise

Do not need any special maintenance

Standards: GB/T 20840.1, GB/T 20840.2, IEC 61869-1, IEC 61869-2, IEEE C57.13, AS 60044-1
