The pollution flashover on high voltage insulators

Electric Power Systems Research, 2008
The pollution flashover, observed on insulators used in high voltage transmission, is one of the most important problems for power transmission. It is a very complex problem due to several factors such as the modeling difficulties of complex shapes of the insulators, different pollution density at different regions, non-homogeneous pollution ...

Flashover of a Liquid Conducting Film Part 1: Flashover Voltage

IEEE Transactions on Electrical Insulation, 1982
We have studied the phenomenon of flashover in a configuration related to that of flashover of high voltage insulators under polluted conditions: a glow discharge is struck at the surface of a liquid, and if the applied voltage is above a critical value, flashover occurs.

Determination of Critical Flashover Voltage and Standard Deviation from Flashover Probability Data

IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1969
A method of determining the standard deviation and critical flashover (CFO) of flashover probability data which utilizes simple graphical techniques to obtain estimates of the parameters is developed. Suggestions are made regarding testing procedures to optimize information gained with a given number of voltage applications.

Effects of soluble constituents on insulator flashover performance and flashover voltage prediction

2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2015
Pollution materials affect insulator flashover performance, and there is long-term significance in researching it. In this paper, common kinds of nitrates were used as the soluble pollution, and the ac flashover tests of typical glass insulator were carried out. During the tests, the samples were polluted by dipping method. Also, up-and-down method was

Effects of the contour of DC insulators on icing flashover process and flashover voltage

Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat. No.03CH37417), 2004
In this paper, laboratory investigations of discharge processes and flashover performances in the low pressure and icing conditions of the high altitude areas simulated in the artificial climate chamber were carried out on XZP-160, XWP4-160 porcelain insulators, FC160P/C170DC glass insulator and lO kV DC composite insulator.

Flashover voltage of artificially contaminated surfaces

Proceedings of the Institution of Electrical Engineers, 1971
Tests were carried out to analyse the influence of geometrical and physical parameters of a contaminating layer on the flashover of small flat surfaces. The wet-contaminant method was used, and the alternating and direct flashover voltages were related to different values and distributions of thickness, width and resistivity of the contaminant layer ...

Flashover Mechanism of High Voltage Insulators

IEEE Transactions on Power Apparatus and Systems, 1979
The elementary phenomenon involved in flashover of high voltage insulators is the propagation of a discharge at the surface of an electrolyte. The study reveals two requirements: 1-Electrical conditions (applied voltage and discharge current) have to be fulfilled so that the discharge can be sustained by the power source throughout the elongation ...

Flashover voltage of contaminated insulators

Conference Record of the 1988 IEEE International Symposium on Electrical Insulation, 2003
Methods have been developed for the calculation of flashover voltage of contaminated circular strip models and outdoor insulators of practical but simple geometric shape. The criteria for discharge elongation and the assumptions made are examined. A typical flow diagram of the programs for evaluating the critical values using the equations derived is ...
