Abstract
The present disclosure relates to a method for detecting a DC magnetization in a transformer and controlling the transformer, the method including: sensing, using at least one vibration sensor, at least one vibration on at least one surface of the transformer or on at least one surface of a component connected to the transformer; measuring the sensed at least one vibration; detecting, based on the measured at least one vibration, the DC magnetization in the transformer; and controlling, based on the detected DC magnetization, the transformer. The present disclosure also relates to a respective device and system.
