Abstract
1442812 Electric protective systems ROBERT BOSCH GmbH 18 July 1973 [20 July 1972] 34312/73 Heading H2K [Also in Division G4] In a system for detecting when loads 20, 32 are open circuit in which, under normal conditions, the current in the supply lead, as 21, saturates a ferrite core 24 and thereby prevents pulses on an input lead 39 linking the core from being picked up by a read-out lead 35, operation of the fault indicator 27 is suppressed when no voltage is being applied to the load. In Fig. 4 suppression is effected by an AND gate 37 having inputs connected to the load voltage and the read-out lead respectively. The embodiment of Fig. 5 employs a compensating core on which the read-out lead 35 is wound in the opposite direction with a number of turns equal to the number of loads used. In the embodiment of Fig. 7 wherein pairs of loads may be connected to the supply source, the read-out lead is guided in opposite directions through the separate ones of each pair. The arrangements of Figs. 8, 10 (not shown) involve a fourth compensating lead guided through the core and carrying a current equal to the load current.
