ABB REG670AISCWO16I0828 PROTECTION RELAY

Product Description

REG670 IED (Intelligent Electronic Device) provides protection and monitoring for generators, prime movers, and step-up transformers in hydro, pump-storage, gas, combined cycle, steam, and cogeneration stations. With excellent performance, flexibility, and scalability it fulfills the demanding requirements, in every corner of the world, for both new installations and retrofits.

Based on Hitachi Energy's extensive experience, REG670 takes generator protection to a new performance level. Up to 24 analog inputs permit integration of main and back-up protection in one IED. Alternatively, additional objects, such as transformers, can be included in the generator protection scope. This enables full duplication of the protection in main one and main two. These features allow a reduction of the number of IEDs needed to protect the entire generating station, increasing availability at the same time. This, in turn, simplifies the installation and reduces its lifecycle cost as related to commissioning, maintenance, and spare parts. REG670 functionality also incorporates intelligent fault criteria, ensuring unrivaled selectivity and sensitivity.
