Abstract

1529377 Phase sequence discriminators DEFENCE SECRETARY OF STATE FOR 1 July 1977 [8 July 1976] 28541/76 Heading H2K A phase sequence discriminator comprises an RC circuit R 1 , R 2 , C 1 , C 2 which generates (across C 3 ) a signal greater than a predetermined threshold level only if the phase sequence is correct, and an electronic switch S connected in one of the phase conductors A and triggered into conduction via a threshold device Z when this level is exceeded.
