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.
- Detects mains (utility) failures when in parallel with another supply
- .Eliminates the possibly of power being supplied into an islanded grid.
- Provides accurate & complete protection.
- Positive sequence over voltage/negative sequence under voltage.
- Detects imbalances in the measured system.
- Zero sequence over voltage protection (NVD protection).
