These grid automation relays are designed for remote control and monitoring, protection, fault indication, power quality analyzing and automation in medium-voltage secondary distribution systems.
With RER615, grid reliability is enhanced, ranging from basic, non-directional overload protection to extended protection functionality with power quality analyses. RER615 supports the protection of overhead lines in isolated neutral, resistance-earthed, compensated and solidly earthed networks.
RER615 are members of ABB’s Relion® product family.
