Products | Automatic Synchronizer

This module is a further development of Grid Synchronizer Relay. It automates Prime mover (Turbine) governing and Field excitation. It comes with numerous built-in protection features as well. In hydro applications, water level sensing and flow control are also built into this module ensuring maximum power output all the time.
