A considerable amount of power transformers in operation do not own Original Equipment Manufacturer (OEM) technical support. It is desirable and feasible to obtain the related design information by interpreting …
Classification of Transformer Windings Types Using Frequency Response Analysis by Machine Learning Method Read MoreAt the University of Queensland we have always focused on higher degree research training. In the recent past, a number of our students have graduated with their PhDs and MPhils …
Transformer Related Post Graduate Research Training at the University of Queensland (UQ) Read MoreIntroduction The failure of transformers can result in safety issues and economic losses. Although FRA is widely used to detect mechanical winding deformation, the success of this technique lies in …
Interpreting First Anti-Resonance of FRA Responses through Low Frequency Transformer Modelling Read MoreThe prebreakdown and breakdown phenomenon in liquids is termed as ‘Streamer’. To better understand the mechanism of liquid breakdown, we need to have deep insights into the streamer process, which …
Magic to visualise the invisible: a comparison on the optical methods to visualise streamers in insulating liquids Read MorePartial discharge (PD) detection is commonly used for power transformer diagnosis. During PD process, electromagnetic emission, acoustic emission and optical emission can be detected, associated with chemical traces left simultaneously …
Beat the Detection Limit of Partial Discharge Acoustic Emission within Transformer by the Use of Fiber Optic Sensor Read MoreIntroduction Transformer tank vibration mainly originates from the core and windings vibration, and they can be easily acquired. Therefore, the vibroacoustic signals of a transformer tank are widely adopted to …
