Mains Decoupling Relay

The DSEP100 G99/G59 Mains(utility) Protection Relay detects changes in the mains (utility) supply to which the distributed energy resource (DER) is connected.

If a mains (utility) failure is detected, the DSEP100 will disconnect the equipment in line with national and international DNO requirements.  This removes the risk of an islanded grid being formed and protects DER equipment.

DSEP100 is suitable for use with all DER equipment supplying power in parallel with the mains (utility) supply.  This includes diesel generators and renewable energies such as photovoltaic (solar) and wind turbine installations etc.

The DSEP100-02 G99 type tested variant is supplied with pre-configured settings to comply with G99 that cannot be changed by the user.
