Description
GE B216LSIG
Technical Specifications:
- Brand: General Electric (GE) Multilin
- Model: B216LSIG
- Product Type: Line Protection / Differential Relay
- System Compatibility: GE Multilin Protection Platform
Functional Features:
- Differential Protection: Accurately compares currents at multiple terminals to detect internal faults with high security.
- Advanced Filtering: Utilizes digital filtering techniques to prevent misoperation during transient conditions.
- Event Recording: Captures detailed oscillography and event logs for post-fault analysis.
Application Scenarios:
Deployed in utility transmission networks, industrial cogeneration facilities, and critical infrastructure power distribution.
Performance Parameters:
- Dependability: Guaranteed operation for internal faults within specified zones.
- Security: Restraint algorithms prevent false tripping during external faults or CT mismatches.
Material Composition:
Rugged industrial enclosure with high-reliability PCBs, precision current sensors, and gold-plated output relays.
Structural Characteristics:
Standard rack-mountable relay form factor featuring a front-panel display, navigation keys, and status LEDs for real-time monitoring.
Working Principle:
Continuously samples line currents and communicates with remote relays. It calculates the differential and restraint currents, tripping the breaker only when the differential current exceeds the restraint threshold.
Installation Requirements:
Ensure proper CT polarity and ratio matching. Verify communication channel latency and synchronization between local and remote relays.
Usage Precautions:
Always use the manufacturer-approved software for setting and configuration. Perform primary and secondary injection testing to verify protection zones before energizing the line.
