ABB REG670 Generator Protection Relay

Application

The REG670 is used for the protection, control, and monitoring of generators and generator-transformer blocks, from relatively small units up to the largest generating units. It is especially suitable for applications where the IEC 61850–8–1 Ed 1 or Ed 2 station bus features of the REG670 can be fully utilized. The control is performed from remote (SCADA/Station) through the communication bus or from local HMI. Different control configurations can be used, and one control IED can be used per bay or one IED can be common for several bays. Interlocking modules are available for all common types of switchgear arrangements. The control is based on the select before execute principle to give the highest possible security.
