Prediction of Flashover Voltage of Insulators Using Low Voltage Surface Resistance Measurement

Design of an artificial neural network for the estimation of the flashover voltage on insulators

This work attempts to apply an artificial neural network in order to estimate the critical flashover voltage on polluted insulators. The artificial eural network uses as input variables the following characteristics of the insulator: diameter, height, creepage distance, form factor and equivalent alt deposit density, and estimates the critical flashover voltage. The data used to train the netwo...

Computation of AC flashover voltage of polluted HV insulators using a dynamic arc model

Flashover of polluted insulators is still a serious threat to the safe operation of a power transmission system. Despite the extensive investigations carried out on the pollution performance of the insulators, the flashover characteristics are not well understood. Recent theoretical and experimental research on polluted insulators is yet to yield a perfect generalized mathematical model which c...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Designation of an Indicator for flashover prediction of porcelain and glass insulators based on experimental tests.

Flashover of polluted insulators in contaminated areas is one of the most important factors influencing the operation of transmission and distribution lines and finally line outages. Therefore, it is essential to prevent and detect flashover in the insulators. Hence, utilizing the insulator status monitoring systems and predicting their functions have absorbed a lot of attention over the recent...
