Core Functions

REF610 is dedicated for medium‑voltage feeder circuit protection, it receives signals from CT/VT current‑voltage transformers, implements fault detection, trips breakers and provides measurement & supervision for distribution linesabb-drive…..

1. Comprehensive over‑current & earth‑fault protection

• Three‑stage phase over‑current protection: instantaneous, definite‑time, IDMT inverse‑time characteristic, for short‑circuit and overload faults.
• Two‑stage non‑directional earth‑fault (ground‑fault) protection, for cable and overhead line ground fault detectionabb-drive…..
• Cable thermal overload protection, phase‑discontinuity protection for broken‑conductor condition.

2. Voltage & frequency supervision Over‑voltage / under‑voltage protection, over‑frequency / under‑frequency monitoring for distribution network abnormal voltage and frequency conditions.
3. Optional auxiliary functions

• Optional arc‑flash protection: detects internal switchgear arc faults, fast tripping to limit equipment damage and protect personnel safetyabb-drive…..
• Automatic reclosing function for overhead line transient faults, to restore power supply automatically after temporary fault clearanceabb-drive…..

4. Circuit‑breaker control & interlock Local and remote breaker trip/close control; programmable digital inputs and relay outputs for switchgear interlock logic; breaker status monitoringManualsLib.
5. Measurement, event recording & fault recording Real‑time measurement of phase current, voltage, power, frequency; stores event logs and fault disturbance records for fault analysis. Front‑panel LCD display and LED indicators for local status and fault indication.
6. Multi‑protocol communication Supports IEC 61850, Modbus‑RTU, DNP3, IEC 60870‑5‑103; connects to substation SCADA, DCS and plant control systems for remote monitoring and setting modification.
