FREQUENCY RELAY Russian patent published in 2005 - IPC

Abstract RU 2244977 C1

FIELD: electrical engineering; electronic frequency relays.

SUBSTANCE: proposed frequency relay that performs dual function of frequency increase and decrease has frequency-dependent component, adder, five threshold units, two AND gates, final component, clock generator, pulse frequency divider, and monostable multivibrator; input of frequency-dependent component functions as input of signal under check and input of monostable multivibrator, as trigger input of frequency relay.

EFFECT: enlarged functional capabilities.
