Abstract

The proposal of this final year project is regarding on the photographic observation for electrical treeing and tracking for detecting line to ground fault via high speed camera. Since formation of electrical treeing and contamination of tracking may lead to breakdown in high voltage system, observation formation of electrical treeing may give an idea on how to reduce the probability of breakdown to occur in high voltage system of line to ground fault as the precaution to prevent the breakdown phenomena in high voltage system especially in high speed rail operation as to control the voltage applied not exceed it limit until it can cause formation bush-like tree that can lead to breakdown. The main purpose of this research is to observe the formation of electrical treeing in line to ground fault using high speed camera that can lead to breakdown due to it initiation and propagation of tree shape. This project will be conducted in high voltage lab in Faculty of Engineering Technology at Universiti Teknikal Malaysia, Melaka. Test will conduct for the glass insulator with rate of voltage supply under 33kV which is it have high dielectric strength due to the constrain of equipment in high voltage lab using high voltage small kit owned by Univeristi Teknikal Malaysia. This glass insulator also use for 33kV distribution network with the suitable environment. This project will use Choronos 1.4 High speed camera and broadband electric field measurement to trigger channel due to the propagation of light since it higher than radiowave using it external channel. The distance of observation for high speed camera will be limited at the distance of 2 to 5 meters inside the safety cage with the resolution of high speed camera will be set up to 5000 frame per second (fps) for the duration of 2 seconds. Measuring parameter of breakdown voltage will be recorded with resolution from 40 to 100 ns ( 10 to 20 MS/s) for 2 seconds duration. Others, electric field breakdown will be recorded via high definition of transient recorder (Lecroy HD04024. Changing of shape are related with the increasing of voltage supply whether it lead to formation of bush, branch, bush-branch and so on. Others, tracking test will conduct to observe the contamination of tracking that can lead to breakdown as the contamination of salt, humidities and so on. Besides, it will analyse time eleapsed for breakdown to occur due to the increasing of high voltage affected by the increasing motion of high speed rail . This can affect the increasing of electric field breakdown due propagation of light is higher compare to radiowave.
