ABB Library is a web tool for searching for documents related to ABB products and services. Technical Reference Manual 3. Introduction Use of the relay The voltage relay REU is intended for over and undervoltage protection in medium voltage distribution networks but can also be used for protection of generators, motors and transformers. The REU is based on a microprocessor environment. A self-supervision system. REU 1MRSMBG 4 Application The over and undervoltage relay REU is a secondary relay which is connected to the voltage transformers of the object to be pro-tected. The over and the undervoltage unit continuously measure the fundamental wave of the phase-to-phase voltages of the object. On detection of a fault, the relay will start.
