ABB REF615 RELAY MANUAL PDF

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.
