GE D60G00HCHF8FH6EMX

Product Overview

The GE Multilin D60G00HCHF8FH6EMX is a configured version of the Multilin D60 line distance protection relay from GE. The D60 is designed for high-speed protection of transmission lines and cables, including applications involving series compensation. It combines protection, control, metering, monitoring, communication, and automation functions within one integrated relay.

As part of the GE Multilin Universal Relay family, the D60 offers a modular hardware architecture. Therefore, its exact capabilities depend on the selected hardware and ordering configuration. The supplied order code should be checked carefully when replacing an existing relay.

Main Specifications

The D60 supports multiple protection and control functions. Depending on the hardware and software configuration, these include phase and ground distance protection, breaker failure, synchrocheck, automatic reclosing, power swing blocking, out-of-step tripping, overcurrent, voltage, and frequency functions.

Protection and Control Features

A major advantage of the D60 is its ability to provide fast and selective line protection. It supports multiple distance zones and can be configured with quad or mho distance characteristics. Advanced options can provide additional zones and sub-cycle distance performance.

Furthermore, the relay supports single-pole and three-pole tripping applications. It can also be used with dual-breaker arrangements and different teleprotection schemes. Flexible programmable logic allows engineers to create customized control and protection sequences without requiring a large number of external auxiliary devices.

Hardware Structure

The D60 uses a modular construction consisting of functional sections such as the power supply, CPU, CT/VT processing, digital inputs and outputs, and communication-related modules. This architecture makes the relay adaptable to different protection system requirements.

The relay can also integrate metering and event information with supervisory systems. Its monitoring functions include current, voltage, power, energy, and frequency measurements, together with oscillography and event recording.

Applications and Maintenance

The GE Multilin D60 is suitable for overhead transmission lines, underground cables, series-compensated lines, and other high-voltage power network applications. It can also be applied to circuits requiring single-pole or three-pole automatic reclosing.

For installation, technicians should verify the complete order code, CT/VT configuration, control power, communication interfaces, I/O arrangement, firmware compatibility, and wiring before energizing the relay. In particular, GE documentation warns that incompatible CPU and CT/VT hardware combinations can cause hardware mismatch errors.

During maintenance, inspect terminals, communication connections, grounding, display operation, and relay diagnostics. Our company can provide the GE Multilin D60G00HCHF8FH6EMX for replacement, maintenance, and industrial power protection projects.
