Abstract

A circuit arrangement for feeding an overcurrent time lag relay 7 has one current converter 2, 3 per phase protected, and the measurement signal and the auxiliary voltage for supply of the relay are both derived from the converter via a rectifier bridge 4. The latter supplies a Zener diode 8 in series with a resistor 9, and the auxiliary voltage is taken off across the Zener diode. <IMAGE>
