TDB... - Sensors for earth leakage relays Type B


TDB series sensors are able to measure AC and DC currents with a DC-10kHz bandwidth, and 1mA reso-lution.  TDB sensors have an integrated degauss function with DC offset zeroing, which is automatically activated at Power On, or by relay command. This function sets to zero the Dc current measuring errors (DC  offset)  caused  by  terrestral  magnetic  field,  permanent  magnets,  DC  coil  ets...,  temperature  drifts,  mechanical shocks or vibrations. The measuring error of the RMS current (AC+DC) is proportional to the line current and it depends on the geometrical layout of the conductors passing through the sensor hole. It also depend on the distance and the geometrical layout of  the nearby conductors passing outside the sensor hole. The IΔn setting <100mA will be possible only by centering the conductors and with controlled environment conditions (temperature, vibration, EMI).
