Current transformers are designed to provide a scaled down replica of the current in the MV line and isolate the measuring instruments, meters, relays, etc. from the power circuit.
Current transformers for outdoor service have several applications.
- Revenue metering.
- Protection for substations and distribution lines.
- Protection for power transformers.
- Protection for capacitor banks.
- Outdoor-outdoor wall bushings (model CPE).
- CR model transformers with epoxy resin internal insulation, cycloaliphatic resin external insulation and active parts located in the central part of the transformer. Up to 72.5 kV.
- CE model transformers with epoxy resin internal insulation, cycloaliphatic resin external insulation and active parts located in the top part of the transformer. Up to 72.5 kV.
- CX model transformers with epoxy resin internal insulation, porcelain or silicone rubber external insulation and active parts located in the central part of the transformer. Up to 72.5 kV.
- CPE model transformers with epoxy resin internal insulation, cycloaliphatic resin external insulation and active parts located around the pass-through primary conductor. Up to 36 kV.
