Transformateurs de Courant de Mesure de Moyenne tension extérieure jusqu’à 69kV
ARTECHE CR series are dry type outdoor 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 C57.13 2008 requirements.
