  • Extended Range Current Transformer (ERCT)
    Extended Range Current Transformer (ERCT)

    Consider using an ERCT (extended range current transformer) instead of an ordinary current transformer because utility companies are employing metered level current transformers for revenue calculation. A regular current transformer may not be able to detect the current when the load is below 5% (off peak duration). In such cases, consumers may be using electrical services free of charge. Use of an ERCT eliminates this problem. CIC is proud to present this cutting-edge product to our global clients.


  • Outdoor Current Transformer
    Outdoor Current Transformer
    AWF-12/24 Series

    CIC outdoor revenue current transformer utilizes a special epoxy which is able to withstand the sun's UV radiation. These current transformers have been subjected to a series of strict environment tests in a bid to provide the most stable & reliable quality for tough outdoor circumstances. They have been supplied to the Taiwan Power Company and to Philippine utility companies for many years, and they have earned an excellent reputation. These current transformers provide an accuracy leve of Class 0.2s, 0.2 & 0.3 (15-25VA burden) and are suitable for 12KV~25KV voltage systems. As a result of the excellent partial discharge test results, our AWF Series current transformer is able to provide users with a long service life.
