Multilin DGCR - Legacy
Advanced Distribution Automation Controller

Manufacturing for this product has been discontinued. As an alternative, please refer to the Multilin R650.

The Multilin DGCR is an advanced Controller for detection of faults and controlling overhead reclosers. The Multilin DGCR is compatible with many traditional and magnetic actuator reclosers and provides a great degree of flexibility in integrating with FDIR systems.

FDIR/FLISR

A key driver and measurement of utility effectiveness is in the reliability of power to its customers. As many faults on overhead distribution lines are transient in nature, reclosing at the substation and installation of mid-line reclosers./switches can improve a utilities SAIDI reliability index by up to 24%.

When permanent faults occur on overhead lines, having feeders with increasing degrees or automation can greatly enhance distribution grid reliability and reduce restoration of unfaulted segments from several hours to a few seconds or minutes. A key component of these automation schemes is intelligent controllers that can integrate with FDIR systems through sharing local information and accepting control commands.

Recloser Control

Robust Design

Based on GE's proven controller platform with tens of thousands of units installed globally, the Multilin DGCR undergoes extensive Accelerated Life Testing (ALT) and Highly Accelerated Life Testing (HALT) to validate accurate functionality under specified conditions and to ensure accurate performance in extreme operating conditions and harsh environments.

Modes of Operation

The Multilin DGCR Recloser controller provides two modes of operation:

  • Remote mode
  • Local mode

The Multilin DGCR recloser controller measures three phase voltages and currents, and based on the measurements, manages Auto-Recloser functionality:
