Description
Product Overview
The GE Multilin MIFIINI01E10HI00 is a multifunctional digital feeder protection relay belonging to the MIF II series, designed for medium voltage feeder circuits in power distribution systems. It integrates protective relaying, metering, fault recording, control and communication functions in a single panel-mount unit. Widely deployed in power plants, substations and industrial power distribution networks, this legacy relay is commonly used as spare replacement and retrofit part for existing protection systems.

Key Features
- Combined protection, measurement, control and fault event recording for MV feeders
- Multi-stage overcurrent and ground fault protection with configurable curve characteristics
- Built-in disturbance fault recorder to capture waveform data during power system faults
- Local HMI keypad and LCD screen for on-site parameter configuration and real-time reading
- Multi-protocol communication interface for connection to SCADA and remote monitoring systems
- Event sequence logging to record trip and alarm timestamps for post-fault analysis
- Rugged panel-mounted enclosure for substation harsh electromagnetic environment
Installation & Testing Notes
- Flush panel mount the relay in the control cabinet, comply with substation EMC shielding requirements
- Verify CT/PT wiring polarity before energizing; incorrect polarity will lead to protection misoperation
- Set auxiliary power supply correctly, confirm AC/DC supply range matches device rating
- After power-up, complete hardware self-test and check LCD status and LED indicators
- Configure protection logic, current thresholds and time delay settings according to power system coordination
- Perform secondary injection test to validate protection pickup and trip action
- This relay does NOT support hot swap; isolate control power before replacement
- Download fault record and event log after commissioning to confirm data capture function
