Product Introduction
ABB REG670 1MRK002826-AC is a Relion 670-series numerical IED designed for generator protection, control, and monitoring in utility and industrial power plants. It is typically deployed on synchronous generators, generator-transformer blocks, and unit auxiliaries where selective protection and fast tripping are required.
ABB REG670 1MRK002826-AC integrates protection elements such as stator differential, over/under frequency, reverse power, and loss of excitation into a single platform. The device uses IEC 61850 communication for substation automation integration, with event recording and disturbance analysis supporting post-fault diagnostics in PCM600 engineering environments.
