Abstract

A core-balance transformer 4 has a core 9 consisting of highly permeable magnetic material the residual induction of which is less than 40% of the saturation induction (measured statically) and the secondary winding of the transformer has a number of turns in excess of 100. The secondary is connected by way of a rectifier 6 to a capacitor 5 which discharges via a voltage-dependent semiconductor element 7, on reaching a predetermined charged voltage, into the coil of a permanent magnet tripping device 8. <IMAGE>
