Product Introduction
The ABB REF615 HBFDACAFNEA1ANN11G fits substations where feeders need combined current and voltage supervision. This configuration supports protection, control, measurement, and supervision of overhead lines and cable feeders in radial, looped, or meshed networks.
It handles non-directional overcurrent, earth-fault, undervoltage/overvoltage, and frequency-based functions. The drawout construction allows quick module exchange with minimal downtime. IEC 61850 support enables GOOSE messaging for station-level integration. In practice, this variant performs well in utility and industrial sites with distributed generation or capacitor banks where voltage stability monitoring matters. Typical instantaneous trip times stay under 40 ms.
