GE Multilin MIFIIPI55E10HI00 Feeder Protection Relay

The GE Multilin MIFIIPI55E10HI00 functions as an intelligent electronic device (IED) focused on minimizing infrastructure damage during overcurrent events. Utilizing digital filtering algorithms, the relay accurately extracts the fundamental frequency components to prevent nuisance tripping caused by harmonics or transient inrush currents.

The structural housing is hardened against severe electromagnetic interference (EMI) and harsh environmental conditions common to substation environments. Its compact footprint ensures it seamlessly fits into standard switchgear panels, optimizing space while upgrading system protection reliability.

• Drawout Case Design: Facilitates rapid testing, maintenance, and replacement procedures without disturbing the permanent panel wiring.

• Dual Power Compatibility: The "HI" designation enables universal operation across standard AC utility lines or high-voltage station DC batteries.

• User-Intuitive HMI: Front-facing LCD screen and dedicated LED diagnostic matrix offer local status verification, real-time current metering, and targeted fault trip indicators.

• Programmable Curve Selections: Features comprehensive inverse time overcurrent curves (ANSI, IAC, and IEC profiles) for exact coordination with upstream/downstream protective devices.

• Industrial Facility Substations: Safeguarding vital distribution feeders in heavy manufacturing, petrochemical plants, and mining infrastructures.

• Utility Distribution Networks: Deployed as primary or backup overcurrent defense lines for radial and loop feeders.

• Motor & Transformer Protection: Serves as a versatile backup thermal and short-circuit protection layer for large transformers and MV motors.

• Q: What does the "HI" suffix indicate in the MIFIIPI55E10HI00 part number?

• A: The "HI" indicates the control power rating. It represents the High Voltage power supply option, supporting 110–250 Volts DC or 110–230 Volts AC.

• Q: Is this relay suitable for systems utilizing a 1A CT secondary circuit?

• A: No. The "55" configuration within this specific model number indicates that both the phase and ground current inputs are strictly designed for a 5A current transformer (CT) secondary.

• Q: How can I download the event records and change settings on this unit?

• A: Configuration changes and event log extractions can be completed via the front-panel RS232 communication port using a compatible serial cable linked to a PC running the GE Multilin setup software.
