A Method, A Monitoring System And A Transformer Arrangement

Abstract: A method (2) for monitoring of structural degradation in a transformer arrangement (3) The transformer arrangement (3) comprises a transformer tank (10) and a transformer (12) enclosed by the transformer tank (10) and immersed in an insulating fluid inside the transformer tank (10). The method (2) is performed by a monitoring system (400) comprising a control unit (1), an actuator assembly (14) controllable to dynamically excite the transformer arrangement (3), and a sensor assembly (16) configured to detect a vibrational response V in the transformer tank (10) of the transformer arrangement (3). The method (2) comprises, by the control unit (1) : controlling S1 the actuator assembly (14) to dynamically excite the transformer arrangement (3); detecting S2, via the sensor assembly (16), a vibrational response V of the transformer arrangement (3); comparing S3 the vibrational response V to a reference response R; and determining S4 a structural degradation of the transformer arrangement (3) in response to the comparison between the vibrational response V and the reference response R exceeding a threshold value. A monitoring system (400) and a transformer arrangement are also disclosed.
