Autosynchroniser Relay is used for paralleling of gensets by matching voltage, frequency, phase angle and zero crossover, internal settings for speed of closure (fst, medium, slow) and breaker close timings. We are a profound manufacturer of the same for our highly valued clients. Relay gives a breaker close signal and locks itself out preventing further commands. Raise / lower signals for frequency and voltage can be used to increase / decrease genset speed and AVR output voltage in our Autosynchroniser Relay. Upto four generators can be synchronised by building control logic to synchronise generators one by one.
