The IME TDGA2 is a closed-core toroidal current transformer with a 28 mm internal diameter, designed for earth leakage detection.
The IME TDGA2 is a closed-core toroidal current transformer with a 28 mm internal diameter, designed for earth leakage detection. It works with IME differential (residual current) relays to monitor leakage currents starting from 30 mA, ensuring protection against insulation faults in electrical systems.
