  • Composite Insulators in a 400 kV AC Line in Algeria for Improving Electric Field Distribution

    Composite insulators are widely used in the 60 and 220 kV transmission lines in Algeria. The reliability of these lines has been improved which leads us to think of integrating this type of insulators in the 400 kV transmission lines recently introduced by the Algerian Company of Electric Power and Gas (SONELGAZ) where glass insulators are used. Thus, in this paper, we evaluated at first the electrical performances in terms of electric field distribution on three proposed composite insulators with different shed configurations under different surface conditions (dry and clean, uniformly polluted and in presence of water droplets). Then, we compared the electric field distribution of the selected composite insulator to the already used made of glass in the 400 kV AC line of TILGHEMT-DJELFA in Algeria under normal and contaminated surface conditions. Using 2D simulation, composite insulators presented better electric field distribution. Finally, the generated heat along insulator surface is estimated for both composite and glass insulators under different surface conditions. Note that an appropriate corona ring is used at both HV and ground ends for glass and composite insulators with constant parameters (corona ring diameter, corona ring tube diameter and corona ring height) throughout the whole study.

  • Brittle fracture of high voltage composite insulators-a new method in inspection and detection

    Composite insulators are widely used on high voltage power lines because of their technical and economic benefits. In the recent years the number damaged composite insulators due to brittle fracture increased worldwide. In the High Voltage Laboratory of Budapest University of Technology and Economics a new technology has been developed to analyze high voltage composite insulators. As a part of a complex expert system this method can identify the critical, severe and hidden failures like brittle fracture with high accuracy. The accuracy, speed, efficiency and reliability of the new method are promising. The differences between the damaged, undamaged and new insulators are significant in the results, thus an all-new complex system is under development. The accurate prediction of critical insulators and power lines is essential because of the large number of damages caused by brittle fracture.

  • Interfacial aging in composite insulators as a result of partial discharge activity

    High voltage outdoor composite insulators used on transmission lines can be subject to degradation due to electrical discharge activity at the core-sheath interface. A methodology is described to explore the effect of de-bonding or loss of adhesion between the sheath and core in composite insulators. The use of planar geometry materials allows interfacial pressure to be varied and facilitates physical and optical imaging of the tracking as it grows and chemical analysis of the samples after aging. The associated electrode geometry allowed the tracking to develop in a constant field, unaffected by the earth electrode. Low pressure between the materials accelerated the growth the tracks. A correlation between partial discharge magnitude and track development is identified. Electrical tree growth was also observed penetrating the epoxy resin, initiated from the interfacial tracks.

  • Mechanical properties of HTV materials used in composite insulators in strong wind area

    Composite insulators were extensively applied in outdoor insulation for the extraordinary performance of hydrophobicity and anti-aging property. Whereas HTV silicone rubber had low elastic modulus and the stiffness was not high enough to resist high speed wind. In northwest China there are many storm-wind areas where the designed wind velocity of transmission lines could reach to 42 m/s. The high speed wind induced sustained and intensive oscillation of insulator sheds and finally leaded to fracture failure at root of it. The oscillation problem of sheds and fatigue and fracture properties of HTV materials haven't been paid enough attention before, for the composite insulators utilized in strong wind area. This paper researched on oscillation performance of one type of composite insulator in wind tunnel with applied wind speed from 0 m/s to 60 m/s. The oscillation phenomenon was recorded with high speed camera to measure the oscillation magnitude and frequency. Four HTV silicone rubber samples were tested for its fatigue resistance performance. The developing process of crack along the groove of silicone rubber samples was observed and the flexing cycles and the cycles that the micro-crack developed into fracture were measured.

  • Effect of uneven wetting on E-field distribution along composite insulators

    The aim of this paper is to study the influence of uneven wetting conditions on the E-field distribution and leakage current along composite insulators under dense cold fog. The tests were carried out in an environmental chamber to simulate natural climate conditions. In the experimental investigation two conditions were considered: the presence of uniform contamination levels and uneven wetting pattern of that contamination under cold fog along insulator surface. The changes in the E-field distribution with uneven wetting on the insulator surface were measured with a spherical probe and field meter. For the E-field distribution, the probe was moved parallel to the axis of the composite insulator. The obtained results suggest that the E-field distribution based on uneven wetting can be an effective tool to evaluate the performance of composite insulators.

  • Research on Rain Characteristics of Composite Insulators

    The rain flashover of insulators in rainy weather is an important factor which affects the external insulation of electric power system. In view of rain flashover problem of insulators, this paper carried out a lot of artificial rain test under different rainfall conditions for suspension composite insulators with different parameters. Selected the number of water column, the number of water droplets and the proportion of the water column to the large sheds spacing as the rain characteristic variables. And the rain characteristics of insulators were studied. Experimental results indicated that rainfall had a significant influence on the rain characteristic variables of insulator. When the rainfall increased, the number of water columns, the number of water droplets and the proportion of the water column to the large sheds spacing increased, and the possibility of bridging between the water column and the water droplets in the two large sheds increased, and the more easily the insulators were flashover. Shed configuration has effect on the rain characteristic variables of insulator. Under the same conditions of rainfall, the larger the rain area of the shed, the more water columns and water droplets between the shed units. The increase in the shed spacing can reduce the possibility of bridging and improve the utilization ratio of leakage distance.

  • Electric field analysis of composite Insulators under dry condition using Charge Simulation method

    In recent years, the service life of Polymeric Insulators is the major part in the electrical field distribution. This paper illustrates electric field and potential distribution in composite insulators under dry conditions using charge simulation method. Electric field is calculated for 500KV both AC and DC line insulators using MATLAB and graphical representations are shown in this paper. In this paper, ring charges are used for calculating electric field and potential distribution in both insulators due to symmetrical characteristics of insulators and the results are obtained under dry condition.

  • Study on electrical properties and field solutions of water related heating of composite insulators on 500kV AC transmission lines

    In 2011, a composite insulator in Shenzhen suffered fracture. Through infrared thermal test along the same and neighbor lines, 517 out of 1327 insulators presented with up to or over 0.5°C thermal increase. Early researches demonstrated that humidity was a factor to have effect on heating performance. In order to understand the potential mechanism of heating and provide precaution suggestions, we conducted FEM analysis on both thermal and electrical field; mechanical load test; electrical endurance test; mechanical, microscopic configurational as well as chemical analysis upon 9 problematic insulators and compared several ways to control end side field intensity. Defective interfaces were found. Polarization of insulation material after aging and water penetration was critical to heating. In order to reduce damage, decreasing the end side filed intensity was necessary to lessen heating loss as well as decelerate aging process.

  • Dry transformer bushings with composite insulators — The obvious combination for increased reliability

    This article is aimed at reviewing certain key aspects related to the inner- and outer insulation on dry high voltage condenser bushings fitted with silicone insulators. Some of the subjects covered are how the shed profile design impacts the pollution performance and ageing resistance, and how the selection of manufacturing method and material selection impacts the erosion resistance. Service experience of silicone insulators in South America is presented, as well as comparisons between laboratory testing and field testing in general. Furthermore, two tests on the inner insulation system on dry bushings are detailed. Both on them goes beyond the industry standards and are relevant to verify the performance under certain extreme conditions that may occur.

  • The development of silicone rubber composite insulators in power system

    Power sector is one of the important infrastructures, which gets affected due to disasters leading to disruption in generation, transmission and distribution of electric power. One of the reasons is the deposition of pollutants on the insulators which start conducting during foggy weather conditions resulting in flashover and interruption of power. Amongst the non- ceramic insulators, silicone rubber insulator is better equipped to deal with flashover problems due to its unique hydrophobicity property. The hydrophobicity property of silicone prevents the formation of water forming on surface of insulator. Silicone rubber insulators have many advantages over the ceramic and glass insulators such as good performance in contaminated environment, easy handling, maintenance free, light weight, high strength to weight ratio, high impact resistance etc. Because of these properties it is gaining popularity worldwide and replacing the conventional ceramic and glass insulators in power transmission all over the world. The present paper deals with designing aspects of the silicone rubber composite long rod insulator and testing the same by performing 'Tracking and Erosion test'. As the surface degradation in outdoor applications of either tracking or erosion occurs because of association with arcing over dry bands which develops during or immediately after precipitation. The surface damage, erosion or carbonization results from the heat of the arc and this damage accumulates until the surface between the electrodes can no longer sustain the applied voltage. Tracking and erosion test is a simulated environment testing facility developed at 'ERDA' which simultaneously tests ultra violet light, rain cycle, voltage, heating and salt-fog environment. This is based on IEC 61109 (1992). The performance of the insulator is compared with the conventional porcelain insulator. The results obtained are encouraging.
