Check Synchronous Relay is used for manually paralleling of gensets by matching voltage, frequency and phase angle. We manufacture the same for our highly respected clients. Zero crossover can be detected manually. Check Synchronising Relay gives a breaker close indication. Generator breakers are to be closed manually. We test this on different parameters to ensure its smooth functioning, durability, efficiency, effective usage and easy installation. We have hence gained high rising applaud and demands from our clients in national and international markets.
