Acrel - Model AKH-0.66K Series -Current Transformer (5-1000A/5A)
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. Customer will benefit from reduced labor intensity, lowered operating cost and improved work efficiency. These current transformers can perfectly work with relay protection, measuring and metering devices.
