Medium Voltage Indoor Current Transformers up to 34.5kV
ARTECHE AC series are dry type indoor service current transformers. The core is encapsulated with type B epoxy resin which provides excellent internal dielectric properties and mechanical strength, ensuring a long mechanical and electrical life. The transformer is maintenance free.
The core is built with high permeability grain oriented silicon steel laminations for low losses. The windings are copper wire with copper plate double isolation. The concentric distribution of the coils prevents magnetic flux leakage, achieving greater accuracy and higher capacity to withstand mechanical stresses in adverse operating conditions.
Partial Discharge measurements exceed the IEEE, CAN/CSA and IEC requirements.
