Simulation of a transformer winding for partial discharge propagation studies
TL;DR: In this article, a simulation model of a continuous disc type 6.6 kV transformer winding was used to study the propagation behavior of partial discharge (PD) pulses, where the position of the zeros in the frequency response of the measured current signals can be used to locate the source of the discharge.
Proceedings ArticleDOI
Investigations on sensitivity of FRA technique in diagnosis of transformer winding deformations
TL;DR: In this paper, the sensitivity of frequency response analysis (FRA) method in detecting different types of deformations on a 6.6 kV plain disc type transformer winding was investigated.
Proceedings ArticleDOI
Experimental investigation into the propagation of partial discharge pulses in transformers
TL;DR: In this article, partial discharge (PD) pulses were injected into the winding using a calibrator and the resulting current signals at the line and neutral end terminals measured using wide band current transformers.
Proceedings ArticleDOI
Detection and characterisation of partial discharges in transformer defect models
TL;DR: In this article, a wide-band partial discharge (PD) measurement system was used to determine the type of PD source using the high frequency components of the spectra of the signals generated by discharges.
Proceedings ArticleDOI
An electrical PD location method applied to a continuous disc type transformer winding
TL;DR: In this paper, a 66 kV continuous disc type winding of a distribution transformer is used to investigate the propagation of partial discharges (PD) with the aim of location The winding was modelled, as multiconductor transmission lines with each turn represented by a transmission line This approach results in the model being valid up to a few MHz in frequency.
