摘要：
This paper presents a technique of vibroacoustic analysis of transformer mechanical condition, based on vibration measurement, using an accelerometer attached to the transformers tank. Presented method is based on two assumptions: 1. in no-load steady-state, the source of vibrations is the core, 2. in transient state, after power on, the vibrations are caused by the power winding and core. In the steady-state the signal from the accelerometer is analyzed in the frequency domain and in the transient state - in the time domain. (Time-frequency vibration analysis of the transformer construction).
