The current transformer (hereinafter referred to as the transformer) is suitable for power systems with 50Hz and a rated voltage of 10kV-35kV, which is designed for power measurement and protection.
This transformer adopts a fully enclosed epoxy resin casting structure. Its core is made of amorphous alloy or high-quality magnetic silicon steel sheets wound into a ring shape, with the secondary windings uniformly wound around it. The primary conductor is wrapped with enhanced insulation to prevent inter-turn short circuits. The product’s base plate includes a grounding bolt and mounting holes for installation.
