The GE Multilin D60-K05-HKH-F8L-H67-M8L-P6K-U6D-W6D is a high-speed transmission line protection relay designed for the protection, monitoring, and control of overhead lines and underground cables across various voltage levels. Belonging to the Universal Relay (UR) family, this integrated device provides five-zone phase and ground distance protection with single- and three-pole tripping, supporting complex utility networks and breaker-and-a-half configurations.

Features

Five-zone quad or mho phase and ground distance protection
Supports single-pole and three-pole tripping with phase selection algorithm
Advanced communication options including IEC 61850 Edition 2, Routable GOOSE (R-GOOSE), and PRP zero-failover redundancy
Integrated synchrophasor measurement capability according to IEEE C37.118 and IEC 61850-90-5
Full-color graphical front HMI display with bay mimic visualization and programmable pushbuttons
Built-in pilot-aided teleprotection schemes including DUTT, PUTT, POTT, HYB POTT, DCB, and DCUB
Integrated four-shot dual breaker autorecloser and ten synchrocheck elements
High-density digital I/O modular hardware configuration for versatile switchyard control

Applications

Overhead transmission lines and underground cables
Single and dual-breaker circuits requiring single/three-pole autoreclosing
Circuits with in-zone power transformers and tapped transformer feeders
Lines equipped with Capacitively-Coupled Voltage Transformers (CCVTs)
Series compensated transmission line protection
Backup protection for generators, transformers, reactors, and busbars

Installation Guidelines

Mounting: Designed for standard 19-inch rack horizontal panel installation.
CT/VT Connections: Connect secondary CT and VT circuits to dedicated terminal blocks with proper terminal torque according to system schematic layouts.
Grounding: Secure a solid low-impedance ground connection directly to the chassis ground terminal to ensure safety and transient immunity.
Communications Routing: Fiber optic cables for Ethernet and inter-relay communication must observe specified bend radii limits to avoid signal attenuation.
