GE C60TG3HLH PMU System

Product Overview

The GE Multilin C60TG3HLH is a state-of-the-art Breaker Controller and Protection Relay from the Universal Relay (UR) family. Designed for high-end utility and industrial substations, it serves as an intelligent electronic device (IED) that integrates breaker protection, sophisticated control logic, and monitoring into one unit.

Key Features & Engineering Advantages

• Dual-Breaker Topology Support: The C60 is optimized for "Breaker-and-a-Half" configurations, where it can sum currents from multiple CT sets internally, simplifying the protection logic for a single terminal.

• PMU (Synchrophasor) Ready: Provides synchronized time-stamped measurements that allow grid operators to detect power swings and instabilities in real-time, far beyond the capabilities of standard SCADA.

• Deterministic Logic Execution: GE’s FlexLogic™ ensures that critical control actions (like high-speed reclosing or interlocking) are executed in a fixed time window, regardless of communication traffic.

• Digital Substation Integration: Supports the IEC 61850-9-2 Process Bus, allowing the relay to receive digital data from Merging Units, which reduces copper wiring and increases overall system safety.

• Rugged Reliability: The unit is "substation-hardened," meaning it is tested to withstand extreme EMI, RFI, and temperature fluctuations common in high-voltage switchyards.

• Extensive I/O Customization: The "HLH" hardware code indicates a specific set of high-speed digital inputs and outputs, allowing for complex interlocking schemes without external auxiliary relays.
