SCOPE proudly introduces DIR CT, a CT Polarity Tester specially designed to verify correctness of polarity of current transformers cores in live EHV switchyards. Polarity test is one of the most common yet crucial tests required to be done on current transformers by commissioning as well as maintenance engineers. Even though it is commonly conducted check, there was no all in one simple tool available for this measurement. DIR CT fills this void to perfection. It is expected to significantly reduce the time taken for polarity checks on numerous CTs in substations, especially during commissioning of new substations. It is a must have tool for Testing & Commissioning companies.
