Grid automation REC615

REC615 is a grid automation relay for protection and control, monitoring, fault indication, automation, and power quality analysis in medium-voltage secondary distribution systems, including networks with distributed power generation, with secondary equipment such as medium-voltage disconnectors, switches, ring main units and reclosers.

With REC615 grid reliability is enhanced, ranging from basic, non-directional overload protection to extended protection functionality with power quality analyses.

REC615 meets today’s requirements for smart grids and supports the protection of cable feeders, overhead lines in isolated neutral, resistance-earthed, compensated and solidly earthed networks.
