Description

Brief Product Description

The GE Multilin 750-P5-G5-D5-HI-A1-R is a comprehensive feeder management relay engineered for the advanced protection, control, and monitoring of distribution networks. This SR750 series device integrates high-accuracy metering with sophisticated fault analysis tools to ensure maximum power system reliability.

Product Description

Comprehensive Protection for Distribution Feeders

The GE Multilin 750-P5-G5-D5-HI-A1-R serves as a primary safeguard for industrial and utility distribution feeders. By incorporating specialized inputs for phase, ground, and sensitive ground currents, the relay provides an multi-layered defense against electrical faults. The unit proactively manages feeder health by detecting overcurrent conditions and ground leakage before they escalate into systemic failures. Furthermore, the “HI” power supply configuration ensures the device maintains operation during significant voltage fluctuations, reinforcing the stability of the protective logic in volatile environments.

Advanced Data Capture and Fault Diagnostics

Beyond standard protection, the 750-P5-G5-D5-HI-A1-R relay functions as a high-resolution diagnostic tool. The integrated oscillography feature samples AC input voltages and currents at high speeds, storing the waveform data alongside the real-time status of logic inputs and output relays. This detailed record allows engineers to perform post-mortem analysis of trip events with extreme precision. Consequently, facilities can pinpoint the root cause of disturbances, which effectively minimizes diagnostic time and prevents the recurrence of similar faults.

High-Precision Metering and System Logging

The SR750 series hardware includes professional-grade metering capabilities that track essential electrical metrics, including voltage, amperage, frequency, and cumulative energy consumption. Users can leverage the internal data logging functionality to record specific system parameters over user-defined intervals. Because the relay supports various communication protocols through Ethernet routing, this logged data remains easily accessible for DCS integration and energy management reporting. The physical design facilitates seamless integration into standard 19-inch panels, providing a compact yet powerful interface for modern substation automation.
