The REF615 is a feeder protection measurement and control device with functions and features including:
Multiple protection functions: REF615 can provide a variety of protection functions, including overcurrent, overload, short circuit, ground fault, overvoltage, undervoltage, overfrequency, underfrequency, etc., to meet different protection needs, and carry out comprehensive and effective fault detection and protection for power equipment.
High-speed circuit breaker control: The REF615 can quickly detect fault signals and control the opening and closing of circuit breakers to achieve rapid fault isolation and protect the safe operation of power equipment and the grid.
Accurate protection measurement: The REF615 uses high-precision digital signal processing technology to accurately measure current, voltage and other signals to ensure the accuracy and reliability of protection.
User-friendly interface: The REF615 has a very user-friendly interface that includes a display, buttons, LED indicators, and communication ports. Users can set parameters, view status, and control operations on the interface.
Cross-phase protection: The REF615's built-in cross-phase protection function can quickly cut off the circuit in the event of an inter-phase short circuit to avoid an extended accident.
Frac fatigue protection: The REF615 features advanced frac fatigue protection to monitor the operating status of equipment in real time and prevent damage caused by overload.
Undervoltage protection: The REF615 monitors the undervoltage situation of the grid and takes timely measures to protect the safe operation of equipment and systems.
These features make the REF615 widely used in substations, industrial distribution systems, and systems containing distributed generators, providing efficient and reliable protection, control, and monitoring.
