Abstract

See full text

An arrangement contains a polyphase transformer which has primary windings and secondary windings. The secondary windings are connected to form a star circuit, the star point of which is connected to earth potential by means of an overvoltage-limiting device. The overvoltage-limiting device has a first overvoltage-limiting component. A switch, which electrically bridges the first overvoltage-limiting component in its closed state, is assigned to the first overvoltage-limiting component.
