Abstract (en)
The present disclosure relates to a surge arrester arrangement for a phase leg winding (2) of a transformer (1). The surge arrester arrangement comprises a plurality of series connected surge arresters (3) comprising at least a first surge arrester (3a) and a second surge arrester (3b) configured to be connected across the winding from a first end (2a) of the winding to a second end (2b) of the winding. The arrangement also comprises an intermediate connection (4b), between the first and second surge arresters and configured to connect to the winding such that the first surge arrester is connected across a first section of the winding formed between the first end and the intermediate connection and the second surge arrester is connected across a second section of the winding formed between the second end and the intermediate connection. The arrangement also comprises a plurality of bushings (6) configured to allow connections (4) to the series connected surge arresters to pass through a wall of a transformer tank (5) containing the phase leg winding.
