Abstract
A classification of voltage-sensitive relays for protection of one-phase residential electrical customers against prohibitive voltage deviation in the supply main is presented. Main indications of voltage-sensitive relays’ classification are selected: purpose, design, relay’s nominal capacity and design current, way of technical implementation, type of output commutation element, voltage operating levels, time delay of reclosing, signalization of the relay’s state, presence of internal protections, presence of additional functions, etc. The presented classification ranges information regarding structural, technical and functional peculiarities of such relays as well as demonstrates state-of-the-art of them.
