The ABB REF615C_E is a Swiss-made relay protector, part of ABB's REF615 family, which is an electronic device designed for protection and control tasks in power systems. Here are some of the key features and application scenarios of the relay protector:

Multi-function integration: REF615C_E integrates protection, control, measurement, communication, monitoring and arc protection and other functions, based on the international standard IEC 61850 platform development and design, to support the interoperability and horizontal communication of intelligent equipment in the station.

Flexible configuration: The protector can be used as the main protection of overhead lines and feeders in the distribution network, and can also be used as the backup protection of transformers and other equipment. It has 7 standard configuration applications to meet different user needs.

Protection logic and functions: Provides directional or non-directional overcurrent and ground fault protection, overvoltage, low voltage, zero sequence voltage protection, thermal overload protection, sensitive grounding protection, and quick-break grounding protection (including intermittent grounding protection). Multi-turn reclosing function is also integrated.

Arc protection: With optional accessories, the REF615C_E can directly integrate three arc protection channels for arc detection and rapid protection of switchgear circuit breakers, cables and bus rooms.

Control function: Support local and remote control function, the user can realize the circuit breaker through the control button on the panel or background monitoring system (SCADA) operation.

Operation Rights: Four levels of operation rights (viewer, operator, engineer and administrator) are defined to ensure the safety and compliance of operations.

Condition monitoring: Provides comprehensive condition monitoring function, monitoring objects include device hardware and software, communication, VT fuse break, current loop, etc., to ensure device protection and system normal operation.

Quick installation and testing: The REF615C_E is pre-configured with common feeder protection logic, which allows users to quickly install, test and accept, and in special cases can be reprogrammed through the signal matrix (SMT) in the PCM600.

Front panel design: The plug-out structure is used to improve the efficiency of user installation and testing of the device, and automatically short the CT secondary circuit when the plug-in unit is pulled out to ensure safety.

Man-machine interface: Powerful but simple and compact design, front panel optional size two kinds of LCD screen, display up to 10 lines of characters, support Chinese, improved panel operation button more intuitive.

Modular design of input/output unit: Support more analog, switching input/output, enhanced fault recording function, etc.

ABB REF615C_E relay protectors are widely used in power substations, power plants and other power industries, as well as industrial users such as cement, metallurgy, petrochemical, automobile, semiconductor, paper, tobacco, etc., and can also be used in municipal, airport, port, real estate and other industries.
