Health Assessment of Oil-Paper Insulation Using Short Duration Frequency Domain Response
TL;DR: In this article , a Lissajous pattern-based technique was employed to identify dissipation factor and % paper moisture in oil paper insulation, which is capable of identifying moisture within a few seconds.
Proceedings ArticleDOI
A Method to Predict Degree of Polymerization Value of Oil-paper Insulation Using Interfacial Charge
TL;DR: In this paper, an attempt is made to develop a methodology to predict degree of polymerization (DP) value based on non-invasive testing of oil-paper insulation, and it is found that DP value maintains a well-known relation with interfacial charge (estimated using Polarization Depolarization Current data) as both these parameters are related to the cellulosic condition.
Proceedings ArticleDOI
Effect of Measurement Temperature on Interfacial Charge Freed from Deep Traps Located at the Interface of Oil-Paper Insulation
TL;DR: In this article, the effects of temperature on deep traps are analyzed and it is shown that magnitude of charge freed from deep locations maintains a correlation with measurement temperature and paper conductivity.
Journal ArticleDOI
Modeling of self consistent field due to volume charge using charge simulation method and method of characteristics line
TL;DR: In this article, the authors presented a numerical solution of electric field that is modified by the presence of volume charge within the region of interest, where charge simulation method coupled with the method of characteristics line is used to provide the numerical solution for the charge modified field.
Proceedings ArticleDOI
Assessing the condition of Nomex paper-based Insulation in Open Wound and VPI type Dry-type Transformer using Frequency Domain Spectroscopy Data
TL;DR: In this paper, the effect of thermal aging of Dip-Bake type and VPI type dry-type transformer insulation samples constructed in the laboratory is described and compared with frequency domain spectroscopy (FDS) data for both the dry type construction.
