Zusammenfassung:	A switch apparatus (10) for a measuring device (30) for a transformer comprises controllable switch means (14) which are configured to short-circuit respectively assigned terminals (11) of one of a plurality of windings of the transformer. A test apparatus (40) comprising the switch apparatus (10) and a method (50) for operating the switch apparatus (10) are also disclosed. With apparatuses (10, 40) and methods (50) according to the exemplary embodiments of the invention, the work effort, time expenditure and errors and inaccuracies can be reduced through an automated testing of transformers.
