MIFIIPI11E20H100 Feeder Protection Relay

Advanced Feeder Protection Relay for Power Distribution

Technical Specifications

Main Features and Advantages

Comprehensive Feeder Protection: The GE MIFIIPI11E20H100 provides advanced protection functions including directional overcurrent, earth fault detection, and voltage protection. Its adaptive protection algorithms automatically adjust settings based on load profiles, preventing nuisance tripping while maintaining critical equipment protection.

Advanced Metering Capabilities: Beyond protection, this relay delivers Class 0.5 accuracy for comprehensive power quality monitoring. It measures 40+ parameters including harmonics (up to 31st order), THD, power factor, and energy consumption, enabling detailed system analysis without additional metering devices.

Cybersecurity Hardened: Designed for modern grid security requirements, the GE MIFIIPI11E20H100 features role-based access control, encrypted communications, and audit logging compliant with IEC 62351 standards. Secure boot technology prevents unauthorized firmware modifications, while configurable firewalls protect against cyber threats in networked environments.

Intuitive User Interface: The high-resolution color LCD displays real-time system parameters, event records, and oscillographic waveforms. Front-panel navigation buttons and USB port simplify configuration and data retrieval, reducing commissioning time by up to 40% compared to conventional relays.

Robust Industrial Design: Engineered for harsh environments (-40°C to +70°C), the relay features corrosion-resistant components and vibration-proof construction. Dual power inputs ensure continuous operation during voltage transients, while self-supervision diagnostics continuously monitor relay health.
