DSEP100 Mains (Utility) Decoupling Relay
The DSEP100 detects and protects multiple devices that generate power in parallel with the mains (utility) supply. Examples include diesel generators, photovoltaic (solar) installations and wind turbine installations.
The DSEP100 ensures that all mains (utility) failures are detected. When detection takes place the mains (utility) supply is disconnected from the local source in line with international requirements. This removes the risk of power being supplied to an islanded grid.
