“…Several studies have carried out the characterization of leakage currents in porcelain, glass and semiconducting glazed insulators based on equivalent circuit-based simulations. The contaminant analyzed is salt water [7][8][9]. In addition, several studies have conducted FEM simulations to determine the effect of contaminants on insulators [10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

There are three types of insulators, namely glass, ceramic, and polymer. Although polymers have hydrophobic properties that make them superior to other materials. However, in its application, ceramic and glass insulators are still used because they are cheaper. Environmental conditions around the work location of the insulator greatly affect its performance. Areas with high levels of pollution will result in the insulator being damaged quickly. The effect of seawater and fly-ash contaminants on the three types of insulators is discussed in this study. Experimental approaches and FEM-based simulations have been carried out. Pollution levels in seawater contaminants were standardized using ESDD. Meanwhile, the level of pollution in fly-ash contaminants is standardized using NSDD. Simulations and experiments were carried out at four levels of contamination, namely light, medium, heavy and very heavy. Then the simulation and test results are compared. The greater the ESDD and NSDD values, the greater the leakage current.

“…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.
