FIELD: power equipment test engineering; testing static wound apparatuses such as transformers or reactors. SUBSTANCE: method involves exposing apparatus structures to action of vibration exciter or impact facility, determining (directly or indirectly) action characteristics, and recording vibration response signal arriving from apparatus structures; used as such is voltage across winding leads. EFFECT: reduced labor consumption, provision for testing hard- to-get-at places. 7 cl
