In this paper, a winding condition assessment model using vibration signals is presented,
which can be used to diagnose power transformers online. The basic principle of this model …

The vibration of a transformer tank is related to the transformer's noise radiation and health
condition. Therefore, it is important to understand the transmission of vibration from internal …

The large current flowing through transformer windings during external short-circuit events
causes strong vibration, and the tank emits multi-frequency sound. This paper investigates …

Winding vibration leads to the oscillation of coils position and further affects winding's
nonlinear stiffness as well as electromagnetic forces (EMFs). This paper establishes a …

In this paper, a novel probability-based classification model is proposed for real-time fault
detection of power transformers. First, the transformer vibration principle is introduced, and …

Transformer tank vibration has been used for the condition monitoring and fault diagnosis of
power transformers, as well as for the evaluation of radiated sound power from such power …

Short circuit (SC) strength of a power transformer is influenced by its winding clam**
pressure. The required level of clam** pressure is selected at the design stage based on …

We report on compression behaviors of oil-immersed insulating pressed-boards used in
transformers for analyzing the axial vibration of windings. Compression behaviors of oil …

Mechanical faults in the winding are often related to the changes in the vibro-acoustical
response of the transformers with respect to the electromagnetic force in winding …

Vibration-based transformer condition monitoring aims to identify the conditions of a
transformer's internal structures, such as its windings and core, by measuring the vibration of …
