It is programmed to strict parameters dictated by the DNO, typically including voltage, frequency, ROCOF (rate of change), phase angle etc. If the parameters are breached then the relay will cause a protective device, such as an MCCB or other circuit breaker to open, instantly disconnecting the generator from the grid.
