In recent years, vibration signals have been widely applied for the identification of
mechanical states in oil-immersed transformers. This paper, following the framework of …

The converter transformer is a special power transformer that connects the converter bridge
to the AC system in the HVDC transmission system. Due to the special structure of the …

It has been over two decades since the publication of pioneer works about the power
transformer diagnostics based on monitoring of their acoustic fingerprints. Since then, there …

On-line monitoring and diagnosis of transformers have been investigated and discussed
significantly in the last few decades. Vibration method is considered as one of the non …

The vibration of the winding and the iron core is the main source of the vibration of the
converter transformer tank, and the vibration measurement and characteristic analysis are …

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 …

In this paper, we present a low-cost health assessment system for oil-immersed service
transformers using a monitoring device to measure energy in real time. By assessing the …

Vibration signal classification plays an important role in operation monitoring of mechanical
structures. In this paper, a novel end-to-end framework is proposed for intelligent vibration …

Power transformer emits continuous vibration signals during working, which contain plenty
of impulses and fluctuations caused by mechanical faults, and these signals are the main …

Study of the vibration mechanisms of transformer windings may lead to useful applications of
vibration techniques to transformer online diagnosis. In a power transformer, the clamping …
