A switch apparatus () for a measuring device () for a transformer includes controllable switch device () which are configured to short-circuit respectively assigned terminals () of one of a plurality of windings of the transformer. A test apparatus () including the switch apparatus () and a method () for operating the switch apparatus () are also disclosed. With apparatuses () and methods () according to the exemplary embodiments, the work effort, time expenditure and errors and inaccuracies can be reduced through an automated testing of transformers.

Switch apparatus, test apparatus and method for operating a switch apparatus for a measuring device for a transformer

For testing a transformer () the transformer () is emulated by an equivalent circuit () and an accuracy of the transformer () relative to the equivalent circuit () is determined by evaluating a test response of the transformer () and is then automatically converted to an operating condition-related accuracy of the transformer ().
