Current Transformers

Current transformer (CT) is a device used to reduce the alternating current levels from several hundreds or thousands of amperes down to a useable value. The current transformers are commonly connected to meters and relays for current measuring and protection purposes, fulfilling your commercial facilities’ power grid monitoring and current measuring needs.

Acrel offers a full range of current transformers including split-core, solid-core, low voltage, medium voltage, and flexible current transformers (rogowski coils) for converting high alternating currents into secondary current of either 1A or 5A.
    1. Split Core CT
    2. Split Core CT AKH-0.66K split-core current transformers are built primarily for power grid construction or retrofit projects. The current transformers can be easily installed onto an existing power system without removing the primary busbar or shutdown the system, guaranteeing customer’s daily use of electricity. Read More
