<p>794,070. Voltage. GENERAL ELECTRIC CO. Feb. 17, 1956 [Feb. 17, 1955], No. 5025/56. Addition to 793,278. Drawings to Specification. Class 38 (4). In a system for controlling parallel connected circuits supplying a common load wherein two circuits are each provided with automatic voltage regulating apparatus responsive to the load current and to the direction of energy transfer by the circulating currents as in the parent Specification, the arrangement for detecting the direction of energy transfer comprises a polarized relay in a balanced modulator circuit. The sensitivity of the detecting circuit is reduced by the addition of series resistors in the modulator circuit when the circulating currents are excessive. Specifications 587,.881 and 589,853 are referred to.</p> |
