“…Contamination increases the leakage current, as well as the aging process. We confirm this fact in our experimental study [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. However, the changes in the leakage current, comparing results at different pollution levels, are not so significant.…”

“…Others use the salt fog method, included in the standard IEC-61109:2008 [ 10 ]. This method uses a chamber to ensure the uniformity of the contamination on the entire surface and a clean comparison between different levels of the amount of salt [ 11 , 12 , 13 , 14 , 15 ]. Another method used is pre-contamination with a set solution of salt, water, and kaolin.…”

Insulator diagnostics is still a topical issue. No one has yet found out how to accurately determine the condition of all insulators and decide when replacement or maintenance is required. Insulators are one of the main components of a transmission and distribution system and must withstand high voltages in all weather conditions. Moisture and dirt are the main factors influencing the insulating properties of insulators. This article deals with the effect of pollution on a porcelain insulator. An Omicron MI 600 measuring system monitors the changes in the dielectric loss factor and leakage current in a wide frequency range (10 Hz to 1 kHz) to evaluate the contamination level. We applied three high voltage levels (5 kV, 7.5 kV, and 10 kV) to the porcelain insulator to monitor changes in the mentioned quantities with various frequencies. The measurement results confirmed the usability of the dielectric loss factor and leakage current for the diagnosis of insulator pollution. The dielectric loss factor showed more promising results than the leakage current.

“…Several traditional insulator materials such as porcelain, ethylenepropylene-diene-monomer rubber, and RTV coated silicone rubber have been compared, and the silicone provides the best flashover performance [7]. Data on flashover voltage and leakage current in other literatures indicated that RTV coating can improve the performance of ceramic insulator in clean fog and salt fog circumstance [8]. Removing the aged RTV coatings is also a problem when maintaining insulators, Wang Xilin et.al.…”

With climate change and global warming, there are extreme weather phenomena in some places. Excessive temperature can adversely affect room temperature vulcanized silicone rubber (RTV) insulators. Other factors such as air pollution, dust, fog, rain, ice and snow, and ultraviolet rays can cause damage to the surface hydrophobicity of the RTV surface and reduce its service life. Contamination from the above factors increases the risk of flashover and corona discharge, which can lead to accidents in the transmission system, resulting in economic loss or personal injury. In recent decades, scientists have investigated a variety of materials that can be compounded with RTV to improve their chemical and physical properties in order to extend the service life of RTV insulators. In this review, we conduct an extensive literature survey and summary on the development and application of RTV coated insulators.

Condition Monitoring of Outdoor High Voltage Insulators, Online and Offline Techniques: A review

2021

View full text Add to dashboard Cite

Outdoor insulator plays a vital role in high voltage transmission and distribution system. The performance and properties of outdoor insulator may severely affect due to various types of pollutants. The failure of insulation in high voltage system results in loss of supply and a huge loss of electrical energy to distribution utilities. In order to reduce power losses and provide a reliable power transmission, selection and design of insulators is very important. To monitor the condition and performance of outdoor insulator in contaminated conditions an appropriate diagnostic technique is required. In this paper various online and offline techniques for conditioning monitoring of outdoor insulators are reviewed under different contaminated conditions. To maintain the healthy environment, the condition monitoring of power line insulators is an important requirement. There are number of techniques that have been introduced to fulfil this requirement. Each technique used at different contaminated condition have their own pros and cons. The findings indicate that the most important effect on the surface of the insulators based on the contamination on the surface leakage current and the flashover voltage. This paper will help in the selection and design of condition monitoring techniques for high voltage outdoor insulator.
