Abstract

1,097,342. Systems operating on two or more sources. RANK-BUSH MURPHY Ltd. May 27, 1966 [May 27, 1965], No. 22596/65. Heading H2H. A circuit for operating a split primary transformer T1 on two voltages comprises a switch PB1, which when a voltmeter V indicates the lower voltage, is closed manually thus energizing a relay RLA which is held over its own contacts and changes the primary windings from series to parallel. The switch SW2 is then thrown to connect the primary windings to the supply. If the supply fails the windings revert to the series connection. If the voltmeter indicates the higher voltage, the switch SW2 alone is thrown.
