  • Current Transformer (CT) Testers - ATEC

    A current transformer tester identifies potentially disastrous current transformer faults, preventing the primary current from overwhelming insulation and in effect causing windings to short circuit. With a CT tester, an engineer can construct a comprehensive testing and maintenance plan to address faults before failures occur and expenses ensue.
