FIELD: testing equipment.
SUBSTANCE: invention relates to testing transformers. Essence: transformer testing apparatus (10) comprises contact terminals (12) for releasable connection to transformer (40), source (13) for generating test signal for testing transformer (40). Device (10) also includes controlled switching means (15) connected to contact terminals (12) during transformer test to short-circuit at least one winding (42) of transformer (40), and control device (17) connected to controllable switching device (15) and configured to automatically actuate controllable switching device (15) at least once to perform transformer test. In this case, control device (17) is configured to automatically activate controlled switching device (15) in accordance with time schedule, which depends on selected test procedure.
EFFECT: technical result: providing automation of transformer testing and reducing amount of work associated with reconnection.
