Dry band formation on HV insulators polluted with different salt mixtures
2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2015Pollution flashover on high voltage insulators is a major problem for power transmission lines. It is a very complex issue due to many factors i.e. modelling and design difficulties, unknown environmental stress, non-uniform distribution of pollution on insulator surface and different pollution levels in different regions.

Formation and characterization of dry bands in clean fog on polluted insulators
IEEE Transactions on Dielectrics and Electrical Insulation, 1999The formation and development of dry bands can best be studied by modifying the standard test procedures. When such controlled behavior is allied with synchronized optical and electrical recordings, then characterization of the pre-formative leakage current, the transient phenomena associated with partial arcs across dry bands, the location of partial ...

Dry Band Formation and Its Influence on Electric Field Distribution along Polluted Insulator
2010 Asia-Pacific Power and Energy Engineering Conference, 2010The formation of the dry band has great influence on the electric field distribution along insulator, which will result in the partial arc as well flashover. In order to investigate the characteristics of dry band under different conditions, a three-dimension model of polluted insulator is established in this paper.

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
This paper presents a theoretical model for evaluating flashover performance of insulators under contaminated conditions. The model introduces several new features when compared with existing models such as, the formation of dry bands, variations in insulator geometry and surface wettability. The electric field distribution obtained from software for 3-

Solid residue formation of RTV silicone rubber due to dry-band arcing and thermal decomposition
IEEE Transactions on Dielectrics and Electrical Insulation, 1998In this study, the solid residue of a RTVSR (room temperature vulcanized silicone rubber) prepared in a tracking test are analyzed. By using the techniques of KBr pellet FTIR (Fourier transformed infra-red) spectroscopy and XRD (X-ray diffractometry), cristobalite SiO/sub 2/, amorphous SiO/sub 2/, amorphous SiO/sub 2/.xH/sub 2/O (namely, silica gel ...

Simplified Numerical Model of Dry Band Formation for Contaminated Insulator
2019The dry band formation process on the contaminated insulator surface consists of phenomena of wetting, conductance change, electrical power consumption, temperature change, and heat transfer and dissipation, which relate to each other in a complicated manner.
