                            What it actually does

                            The REF615 protects and controls power feeders (cables and overhead lines).

                            It performs:

                            • Overcurrent protection (phase faults)
                            • Earth fault / ground fault protection
                            • Short-circuit protection
                            • Thermal overload protection
                            • Breaker control (open/close commands)
                            • Fault recording & event logging
                            • Power system measurement (current, voltage, frequency)

                            ---

                            System Role (Simple)

                            Power line / feeder
                            → CTs / VTs measure current & voltage
                            → ABB REF615 relay (this device)
                            → analyzes fault conditions
                            → sends trip signal
                            → circuit breaker opens

                            Precautions

                            • Requires correct configuration via ABB PCM600 software
                            • Incorrect settings can cause false tripping or failure to trip
                            • Must be coordinated with other protection relays in system
                            • Installation must follow electrical protection engineering standards
                            • Used in medium/high voltage systems → only qualified engineers should configure
