Abstract

1390456 Protective arrangements G WEBER 16 March 1972 [16 March 1971] 12385/72 Heading H2K An over-current arrangement for protecting a thyristor 3 connected in series with a load 1 comprises a control resistor 2, an electronic store, such as a flip-flop 4 or transductor, responsive to the voltage drop at the resistor, and a transistor 5 connected to the store and controlling the conduction of the thyristor.
