Remote Insulator Contamination Monitoring System
IEEE Power Engineering Review, 1997erful features for the formulation of appropriate abstractions for the desired application. But programming is always easier if a specialized language is already available for the creation of similar applications. Specialized applications should use dedicated computational engines where the developer can build and compose with high level constructs. In

Performance of dust-contaminated insulators in fog
Electrical Engineering, 1948This paper presents a discussion of the problem of line insulator contamination by dust and the subsequent performance of the insulators in fog-laden atmospheres. A pioneer investigation of the subject carried out by the Department of Water and Power at Ryan High-Voltage Laboratory of Stanford University is described.

Hydrophobicity and insulated resistance of composite insulators with biological contamination
2016 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2016Biological growth has been observed on insulators installed all over the world. However its impact on the electrical performance is not well known. This paper described the investigations on the performance of post insulators with biological growth at a converter station. Both the ceramic and composite insulators were investigated.

Insulator behavior in contaminated atmospheres
1969 9th Electrical Insulation Conference, 1969The conditions leading to flashover in contaminated atmospheres are very complex and do not always permit simple choices of insulator types for good performance. Increased understanding concerning performance under salt contamination has been realized, and reasonably good correlation between artificially contaminated insulators and pollution under ...

DC contamination performance of station insulators
IEEE Transactions on Electrical Insulation, 1988The authors describe the results of an investigation of the contamination performance of equipment insulators under the application of a DC voltage. Artificial contamination tests on insulators with various shed profiles were carried out. In addition to total leakage distance, shed profile is found to play a role in determining the DC withstand voltage.
