Reclosers are predominantly located on the distribution feeder, though as the continuous and interrupting current ratings increase, they are seen in substations, where traditionally a circuit breaker would be located. Reclosers have two basic functions on the distribution system: reliability and overcurrent protection.
Whether performing three- or single-phase tripping, connecting distributed generation to the grid or communicating via IEC 61850 utilizing GOOSE messaging, the GridShield
recloser for medium voltage outdoor networks is paired with the industry’s most intelligent electronic device - the RER620. In addition, OVR
platform provides a field-proven solution with ABB vacuum interrupters and HCEP Cycloaliphatic Epoxi insulation and magnetic actuators, towards creating a smart grid and allowing grid optimization. Why ABB?
- Solid dielectric recloser - ABB vacuum interrupters & sensors embedded in each recloser pole;
- Magnetic actuator per phase - allows for single phase tripping capability;
- Stainless steel cabinet provides longer lifespan and reliability;
- ABB relays flexibility with all communication protocols available including IEC61850
