“…Flashover depends on the type of pollution and time duration that the insulator is placed in the polluted environment [16]. Industrial, desert, and marine pollutions are the main three types of TL insulator pollution [17,18]. Industrial pollution is caused by industrial plants which produce pollutants such as chemical particles, dust, carbon, and cement and deposited on the insulator surface.…”

High voltage measurements are not only significant for reliable transmission of electricity at high voltage potentials but also play a vital role in different realms and various applications. Their most common applications are in power electronics, medical technology, electromagnetic compatibility, particle accelerators, aluminum production, and electronic ignition systems. High Direct Current (DC) and Alternating Current (AC) measuring devices for high voltage are extensively used in numerous claims. Precise high voltage measurement techniques are crucial to guarantee these measuring devices' performance, assess their standard operating procedures and ensure their measurements' quality. High voltage metrology validates inclusive progresses in science and technology.

Insulators on overhead power lines have long been exposed to the outdoors and are susceptible to pollution and salt contamination. Due to factors such as wind and gravity, pollution in the atmosphere gradually deposits on the surface of the insulator. In humid and windy conditions, conductive pollutants begin to dissolve in the water on the surface of the insulator, increasing the leakage current and affecting insulation performance. This study mainly uses a data acquisition system to measure the leakage current of the insulator and weather parameters (including temperature, relative humidity, pressure, wind speed, and ultraviolet) around the insulator. Artificial intelligence is then applied to establish a prediction model for leakage current based on weather parameters. The established model accurately predicts insulator leakage current through weather parameters. In order to observe the real-time status of the insulator, this study establishes a monitoring platform that integrates the predicted leakage current with weather parameters. It allows users or maintenance personnel to connect to the server through the network to observe the predicted results and weather parameters. The results can establish a real-time salt contamination monitoring system for insulators on transmission lines, enabling operation and maintenance personnel to understand the actual insulation situation of the insulator in real-time. This can not only prevent power outages due to salt contamination or pollution but also reduce the workload for maintenance personnel. Moreover, the maintenance strategy is upgraded from time-base maintenance to condition-base maintenance, significantly improving the efficiency of operation and maintenance for power lines.

“…This is further supported by J.Li [7] that this correlation can be used to determine the pollution severity and the flashover voltage occurrence. Other researcher used the 3rd, 5th, and 7th 𝐼 3 𝑟𝑑 (𝐼 5 𝑡ℎ + 𝐼 7 𝑇ℎ ) ⁄ to analyse the LC under different environmental condition where it has been reported that the 7th harmonic has a considerable effect on the performance of the LC under wetting conditions [8][9][10][11]. N.Bashir [12] used the third to fifth harmonic ratio of the LC to determine the effect of pollution severity on the aged glass insulator.…”

Leakage current has been widely utilized as an effective means to monitor the pollution severity of outdoor insulators. The indices of the odd harmonic components of the leakage current have proven to be reliable indicators of insulator performance, particularly in the third to fifth harmonic orders. However, significant challenges exist in using these indices to monitor and classify the leakage current of aged insulators under varying harmonic and pollution conditions. This paper introduces the harmonic index K((3/(5+7) ) which employs third up to seventh odd harmonic component of the leakage current as a diagnostic tool to determine the pollution severity of aged insulators under light, medium and heavy contamination levels. The experiments were conducted using 12 different sets of 11kV insulators with varying degrees of aging. The results indicate that the harmonic index Ki for new and moderately aged insulators decreases with an increase in contamination and is lower than that of heavily aged insulators.
