Product Introduction
ABB REG615 is a dedicated generator protection relay from the Relion 615 series. It handles protection, control, measurement, and supervision for small to medium generators in diesel, gas, hydro, and steam power plants.
The relay supports IEC 61850 for substation integration and delivers functions like differential protection and stator earth-fault detection. This setup enables cost-effective system upgrades with backward compatibility to existing installations.
