Bay Control IED GBU200

Product Overview

The GBU200 bay control IED has been designed to provide bay control and protection functions for application to transmission lines and distribution feeders in all types of network. The GBU200 provides functions for the control and monitoring of switchgear, transformer and other equipment in EHV, HV, MV and LV substations. It can also support feeder protection functions such as directional overcurrent and earth fault protections within the flexible and user-friendly GR-200 Series platform.
