  • Electric field analysis of polymer insulators for various geometrical configurations

    Present days, electrical field distribution is the region of major concern in the service life of polymeric Insulators. Numerous methodologies are suggested to analyze the electric field along the insulators both experimentally and numerically of which the former might be more time consuming, requiring a number of trial-error tests to decide the optimum dimensions. The dawn of super computers makes numerical analysis feasible on any intricate geometry. Insulators will degrade and fail due to the existence of higher electrical stresses. These electrical stresses can be minimized with change in the geometrical configurations of the insulator. Here in this paper, with the help of FEMM 2D software package 11kV and 33kV polymer insulators are designed and electric field distribution at different critical points is analyzed. The electric stresses are reduced with the change in the geometrical configurations mainly the size and shape of the insulator. Results are compared between the actual design of the insulator and the insulator with the change in the geometrical configurations. It is observed that the insulator with change in geometrical configurations gives better field results.

  • Influence of power source on contamination withstand voltage of polymer insulators

    In general, heavy leakage currents flow on contaminated and wetted insulator surfaces, and so it is specified to evaluate the contamination withstand voltage performance of ceramic insulators in laboratory using a power source stiff enough to avoid a voltage drop. However, it has not been confirmed whether such a requirement is also necessary for hydrophobic polymer insulators considering the relatively smaller magnitude of leakage currents on such hydrophobic insulators. The authors made comparative contamination tests on hydrophobic polymer insulators by a stiff and a weak power sources to evaluate the influence of stiffness of power source on contamination withstand voltage performance of hydrophobic polymer insulators. For reference, porcelain suspension insulator units were also evaluated by these power sources.

  • Effects of Suspension Pattern on Operation Reliability of Anti-Icing Polymer Insulators in HVAC Transmission Lines

    Design and application of anti-icing polymer insulators have been considered as one of effective methods to prevent the icing accretion and icing flashover on outdoor insulators, which is greatly significant to the safety and reliability of power transmission systems. In this paper, according to the actual operation of transmission lines, the wind load and gravity load were calculated under different wind scales. The wind loads and the inclined angles were considered to analyze the axial force of insulator on windward side, the axial force of insulator on legging side and deformation displacement of anti- icing polymer insulators under different meteorological conditions. The obtained results showed that the static axial force distribution, maximum mechanical load and deformation displacement increase with the increase in the wind scales. With increasing the inclined angle of the insulator, the axial tension shows the decreasing tendency from 30° to 60° but then the increasing tendency from 60° to 110°. And the minimum value of axial tension increases gradually with the increase in wind scales. The operation reliability of anti- icing polymer insulators shows the decreasing tendency with the increase in the wind speeds. The optimal suspension pattern with the inclined angle about 60° is also proposed, which can make quantitative optimization analysis on relationship between the typical meteorological condition and operation reliability to improve the reliability and stability of anti-icing polymer insulators in transmission lines.

  • Consideration into CIGRE round robin contamination test of polymer insulators

    Hydrophobic polymer insulators show higher contamination flashover voltages compared with ceramic insulators, but standard artificial contamination test methods have not yet been established. Test methods used for ceramic insulators are now usually used also for polymer insulators, but due to different surface properties and configurations between ceramic and polymer insulators, test procedures and conditions for ceramic insulators may not be pertinent for assessing polymer insulators. Under such circumstances, CIGRE WG C4.303 started round robin tests and results from four laboratories were presented but some differences were obtained. In order to clarify the factors for such differences, effects of ambient temperature, artificial fog injection rate into test chamber and kind of non-soluble contaminants were investigated. Any significant effect of ambient temperature on contamination flashover voltage was not found, but discernible effect of fog injection rate was found on the flashover voltage of longer time rested insulators. In addition, about 10% difference in flashover voltage was found between Kaolin and Tonoko both under the no rest time and the longer rest time conditions.

  • Fundamental investigation results of diagnostic technique for deteriorated polymer insulators

    Polymer insulators are widely used all over the world, owing to their excellent contamination performance, light weight, antivandalism characteristics, etc. Ageing deterioration is, however, inevitable with these insulators due to organic materials used for the weather shed and core, and mechanical and/or electrical breakdown of these insulators are a point of ongoing concern. Diagnostic methods to detect deteriorated polymer insulators are not established yet, although CIGRE SC 22 reported various techniques. Some serious erosions and shed punctures were observed on some of the polymer insulators removed from a 110-kV transmission line in China. Diagnostic tests were made on these insulators in an outdoor test station and the results were compared with those obtained in an artificial fog chamber.

  • Assessment of basic contamination withstand voltage characteristics of polymer insulators

    An artificial contamination method for hydrophobic polymer insulators has been developed which can provide a uniform contaminant layer, similar to that found in nature, without either damaging the polymer surface or by adding any chemical agent to the conventional contamination slurry. Using this method, the basic contamination withstand voltage characteristics of polymer insulators were investigated compared with those of porcelain insulators. The results show that although hydrophobic polymer insulators generally have excellent contamination withstand voltage characteristics, critical reduction of withstand voltage sometimes occurs under rapid and heavy wetting and contamination conditions.

  • Evaluating failures of polymer insulators in Brazilian distribution networks

    Investigations aiming to evaluate cause of failure of polymeric insulators used in Brazilian distribution networks reveal that it is not the presence of internal voids in their bulk but the fissures formed in the vicinity of insulator pins during their installation that cause the failure.

  • Image analysis of hydrophobicity of polymer insulators by observing at microscopic area

    Hydrophobicity of polymeric insulating material surfaces such as silicone rubber (SIR) and ethylene propylene diene monomer rubber (EPDM) insulator was studied by using image data analysis of the sample surface. Using a very high- speed microscope CCD camcorder, we digitized the hydrophobic surface image under the spraying of a mist of water. The size of the observed image area is only about 2 mm/sup 2/, the effect of aging in water and its recovery in air on the hydrophobicity of specimens was measured by the surface images of water droplets on the sample surface. Using this microscopic image, we can determine the hydrophobicity class (STRI's HC level) without the effect of gravity or inclination of the surface to the formation of water droplets on the surface. Image data analysis can calculate the image indexes such as size and shape factor of the droplets. They are also helpful to define the hydrophobicity class more accurately.

  • Effect of insulator configuration on ageing deterioration of polymer insulators

    According to our accelerated ageing test results of 275-kV full scale insulator strings coated with the same silicone rubber, conventional porcelain long-rod insulators showed better anti-ageing performance compared with transmission line polymer insulators. As the reason for such results two factors are considered. One is difference in core diameter, and the other is difference in shed shape. In order to clarify the reason for such results, we started comparative accelerated ageing tests on five different specimens, coated with the same room temperature vulcanized silicone rubber, with almost the same shed shapes but three different core diameters and with almost the same core diameters but three different shed shapes. As of 380 cycles of accelerated ageing test, any discernible deterioration was not observed on any specimens, although partial discharges had been observed at the energized end core surface of the transmission line polymer insulator after 200 cycles. It takes so long to get any significant deterioration by the accelerated ageing test. Since it is considered that the main cause of surface deterioration of polymer insulators is partial discharges, we investigated the partial discharge inception voltages of these specimens under contaminated and wet conditions. The transmission line polymer insulator showed the lowest partial discharge inception voltage. Very large ratio of shed to core diameter is considered to be the cause of easy occurrence of partial discharges due to concentrated voltages allotted at the core surfaces. We prepared three specimens to improve the voltage distribution of the transmission line polymer insulator and evaluated. Promising results were obtained.
