GE Multilin is a protection and control product family used in electrical power systems for equipment monitoring, fault detection, and protective tripping. Its architecture combines protective relays with processor, CT/VT, digital I/O, communication, and process-interface modules depending on the relay platform. Technical characteristics vary by model and ordering code, including current and voltage inputs, protection functions, I/O configuration, communication options, module position, and system compatibility. The collection covers measurement, logic, signal interface, processing, and communication hardware associated with GE Multilin platforms. Functionally, the equipment measures electrical quantities, evaluates configured protection logic, records system events, operates trip outputs, and exchanges data with supervisory systems. Selection should match the relay family, chassis position, hardware revision, firmware generation, electrical input requirements, and complete ordering code.
