Grid automation relays REC615 and RER615

REC615 is a remote monitoring and control relay, RER615 is a recloser protection and control relay

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 REC615 and RER615, grid reliability is enhanced, ranging from basic, non-directional overload protection to extended protection functionality with power quality analyses. Thus, REC615 meets today’s requirements for smart grids and supports the protection of cable feeders likewise RER615 supports the protection of overhead lines in isolated neutral, resistance-earthed, compensated and solidly earthed networks.
