ABB REG670AISCWO16I0828 PROTECTION RELAY

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 Energys 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.

Comprehensive Protection and Advanced Control

The REG670AISCWO16I0828 relay brings together differential, overcurrent, ground fault, distance, under/over voltage, and frequency protections, making it suitable for safeguarding generators, transformers, and busbars. Intuitive push-button controls and a navigation-enabled LCD display offer enhanced usability for operators managing complex power systems.


Flexible Configuration and Easy Integration

Engineered for adaptability, this relay provides 16 digital inputs and 28 outputs, with versatile connection options through screw-type rear terminals. Communication is streamlined via Ethernet RJ-45, RS-232, USB, and IEC 61850, ensuring efficient data exchange and system compatibility for both new and legacy power infrastructures.


Reliable Operation in Demanding Environments

Withstanding temperatures from -25C to +70C and offering >10 million mechanical operations, the REG670AISCWO16I0828 is built for longevity. Its IP20-rated enclosure and high dielectric and insulation strengths guarantee consistent performance in varied conditions, ensuring your power systems remain secure and stable.
