Granted: 1994-06-15
Abstract: FIELD: relay protection of electrical systems. SUBSTANCE: input circuits of primary current 1 and voltage 2 converters are connected to power network in agreement with any known design. Required zone of operation of element (its lower and upper boundaries) are set by corresponding settings of threshold elements 10 and 11. In this case value of angle of shift of phases of current and voltage in power network will be equal to any value lying outside zone of operation of element measuring direction of power. One of threshold elements will be set in state "logic zero" and the other threshold element will be in state "logic one". In connection with this there will be no signal across output of logic AND gate 12. If value of angle of shift of phases of current and voltage in power network will assume any possible value lying within zone of operation of element then both threshold elements 10 and 11 will pass to state "logic one" and signal will emerge across output of logic AND gate 12. EFFECT: enhanced efficiency and reliability of protection. 2 dwg
