FIELD: electricity.
SUBSTANCE: invention is designed for changing taps in power transformers. A modified diverter switch comprises mechanical and electric interface, compatible with a switch body, main and intermediate contacts, a holder of current-limiting resistance comprising an interface coupled with the body of the available tap changer for provision of modification of the diverter switch, besides, multiple modules of current-limiting resistances may be connected together. The diverter switch may comprise a vacuum switch and may be installed in a body of the available tap changer.
EFFECT: invention provides for simple tuning of a diverter switch to user requirements for various use and possibility to modify an on-load tap changer.
