REF Hanover, April 21st - New medium voltage protection device The REF feeder protection relay, specially developed by ABB to meet the requirements of IEC standard, provides not only overcurrent and earth-fault protection, but also measuring, control and monitoring functions. Reliable operation is ensured by a continuous watchdog function and clearly structured status indication by eleven freely programmable LEDs and a display. Together with standard functions such as overcurrent and earth-fault protection, the new REF feeder protection relay provides numerous additional functions including intermittent earth-fault protection, transient-measuring earth-fault protection, thermal overload protection, release circuit monitoring, circuit-breaker status monitoring and three-channel arc protection for enhanced operator safety in air-insulated systems. With the REF, for the first time, there is a protection device on the market which was consistently developed on the basis of IEC from the first steps to the user software. The new device uses the tried and tested withdrawable module technology of the series, but also provides additional protection functions, a higher number of binary inputs and outputs and integrated circuit-breaker control.
