GE B30TG3HLHFXXH

Product Description

Reliable busbar protection is essential for maintaining the safety and continuity of modern electrical networks. The GE B30TG3HLHFXXH Multilin relay is designed to provide advanced differential protection and monitoring functions for industrial and utility power systems.

Built on GE’s Universal Relay platform, the B30 combines protection algorithms, programmable control logic, and electrical measurement capabilities in one device. It helps operators identify abnormal current conditions and coordinate protective actions across connected electrical circuits.

Operating Functions

The relay performs several important functions within a substation protection system:

Bus Differential Protection: Compares current measurements from different busbar connections to identify internal faults and abnormal current imbalances.

Circuit Monitoring: Monitors connected electrical circuits and provides operating information for system supervision.

Fault Recording: Supports event records and disturbance analysis, helping maintenance personnel investigate protection operations.

Programmable Control: Uses FlexLogic to create customized control and interlocking sequences.

Communication: Supports integration with supervisory systems and other compatible protection devices through supported communication interfaces.

Hardware and Design

The GE Multilin B30 features a modular hardware architecture. Depending on the ordered configuration, its internal arrangement can include:

• Protection and processing hardware.
• Power supply modules.
• Current and voltage measurement interfaces.
• Digital input and output modules.
• Communication interfaces.
• Front-panel display and operating controls.

This modular arrangement provides flexibility for different substation protection requirements. The exact hardware and I/O configuration depend on the complete ordering code.
