The cast resin current transformer type GR are post type with wound primary, encapsuled in synthetics resin.
These current transformers offer the following advantages
• Completely dry insulated and suitable for using in any climate
• Leakage trouble free
• High degree of arcing and mechanical stability
• Good behaviour of electrodynamic forces
The GR wound primary current transformers meet the I.E.C 185 standard and can be adapted for compliance with V. D. E and B.S.
Each current transformer is completed with base mounting plate of aluminium alloy, moreover each secondary terminal can be grounded.
Our current transformers have already been type-tested by L.M.K.
