GE L90A00HCHF8AH6UL6UN6CS6UU6CW2A Relay System

GE L90A00HCHF8AH6UL6UN6CS6UU6CW2A Line Current Differential Relay System Description: The L90 provides high-speed current differential protection suitable for transmission lines and cables of various voltage levels. It supports complete distance protection and dual-breaker applications, making it suitable for single and three-pole tripping scenarios. Features: Phase-segregated differential protection: Ensures secure high-speed single-pole tripping. High-speed phase and ground distance protection: 5 zones with independent compensation settings and customizable pilot schemes. Reliable protection for series-compensated lines: Increased sensitivity through dynamic charging current compensation and communication channel asymmetry compensation. Phasor Measurement Unit (PMU): Supports synchrophasor measurement according to IEEE C37.118 (2011) and IEC 61850-90-5. Advanced Cybersecurity: Features “CyberSentryTM” to meet modern industry requirements. IEC 61850 Certified: Ed. 1 and Ed. 2
