The SIL-G is a perfect protection relay for primary distribution which can protect a feeder by means of current, voltage and frequency functions.
It also has the advantage to provide with the main functions to protect a generator protecting decoupling, load shedding and loss of main (islanding). It is normally used with a circuit breaker as cutting element.
Besides, It provides a complete protection working with auxiliary power supply 24-220 Vdc/48-230 Vac or in self-powered mode through the VTs (depending on model).
Integrating the synchronization capability into the generator protection relay through IRIG-B and SNTP optional and Arc Flash detection (AFD) with 4 AFD inputs and 4 high-speed outputs available depending on model provides the most reliable solution.
Main applications: Renewable energy facilities and 36 kV / 66kV / 132 kV substations.
