  • Study on mechanical and electrical characteristics of gossans electrochemical corrosion ceramic insulators on DC transmission line

    Chusui dc transmission line is the world's first ±800kV transmission line in China. 2011 March, gossans of ceramic insulators on ±800kV Chusui dc transmission line appeared electrochemical corrosion at Qujing region in Yunnan province. The corrosion phenomenon concentrated in V-string insulators on negative polarity side. This article describes the basic electrochemical corrosion situation of ceramic insulators. In order to analyze the mechanical and electrical characteristics of electrochemical corrosion ceramic insulators of ±800kV Chusui transmission line, insulation resistance test, mechanical and electrical load destructive test and natural contamination flashover test had been done in National Engineering Laboratory for Ultra High Voltage Engineering Technology (Kunming). Test results indicate that gossans' electrochemical corrosion problem didn't obviously decrease insulators' mechanical and electrical characteristic currently. The electrochemical corrosion insulators still satisfy transmission line's operation requirements. Meanwhile, contamination degree of electrochemical corrosion insulators whose surface is divided into three parts had been measured respectively. Measurement results indicate the contamination severity of electrochemical corrosion products accumulated area on ceramic insulators' surface is much heavier than other area, which indicates that ceramic insulators' gossans electromechanical corrosion would aggravate contamination accumulation. It is necessary to take measures to suppress ceramic insulators gossans electrochemical corrosion.

  • Leakage current properties of field-aged RTV silicon rubber coated & uncoated ceramic insulators

    Insulators have often become the main factor of power system failures which leads to interruption of power system delivery. Thus, ensuring the insulators working properly is an indispensable thing to do. Leakage current (LC) monitoring on the insulators' surface is one of the ways to acquire the condition of insulators. This paper discusses the results of LC monitoring of field-aged ceramic insulators that have been installed in a coastal area of a relatively humid weather. As proven in previous research, RTV silicon rubber coat that is applied on the insulators' surface can reduce the magnitude of leakage current. Therefore, in this research both RTV silicon rubber coated and uncoated field-aged outdoor insulators are monitored from the year of 2012 to 2017 to see the consistency of the results along the aging. There are total eight LC waveforms are obtained from experiment results in four different years, each of RTV silicon rubber coated and uncoated insulators. These waveforms are further recreated through computer simulation using ATPDraw software in order to obtain electrical properties, such as capacitance, nonlinear resistance, and number of arc models. The LC properties that are monitored from the experiment results and become the keys to the computer simulations are LC magnitude, Total Harmonic Distortion (THD), and dominant harmonics.

  • Assessing the integrity of vintage ceramic insulators

    New research performed on old ceramic insulators indicates that such insulators are often weaker electrically and mechanically than expected and may create significant maintenance and reliability problems for electric power utilities. Results of tests on insulators removed from service revealed that mechanical, electrical, and material aging of the vintage insulators was significant. This paper describes the findings obtained to date on the condition evaluation of vintage insulators based on the laboratory tests. While research continues, preliminary conclusions suggest that the estimated useful service life for dead-end insulators is from 60 to 75 years, and for suspension units it is from 75 to 90 years.

  • Inverse application of charge simulation method in detecting faulty ceramic insulators and processing influence from tower

    Suspension insulators are widely used in power systems to provide electrical insulation and mechanical support for high-voltage (HV) transmission lines. To detect and replace the faulty insulators on power transmission lines is of great importance for the safe operation of the power system. A nontouch electric-field measurement method to detect faulty ceramic insulators is presented, which involves measuring the electric-field of measuring points in the vicinity of insulator strings and calculating the potential distribution along HV outdoor insulator strings. It also suggests a way to process the influence from the tower. The salient feature of this method is the significantly smaller number of measuring points and the greater distance between measuring points and insulator strings. Ceramic suspension insulators of 110-kV voltage ratings have been modeled under clean and dry surface conditions. Good agreement is obtained between the present calculations and the actual value, which demonstrates the practical viability of the technique

  • Aging of silicone compound coatings on ceramic insulators under artificial tropical climate

    This paper describes the effects and the aging of silicone compound coatings on ceramic insulators under artificial tropical climate. The improvement of the properties of the ceramics insulators was investigated. The effects of temperature, humidity and various artificial pollutants were also investigated. The experimental results show that application of silicone compound coatings suppressed leakage currents significantly under contaminated environment. The hydrophobicity of the insulators was also improved drastically. Up to 50/spl deg/C the coating performed well and the leakage current was remain constant. Under humidity of more than 90% higher leakage current and lower flash over voltage were observed. The coating on the wet- polluted insulators results in a very poor improvement of the insulator properties. This showed coating method affected the performance of the coating.

  • Dynamic simulation of risk of flashover of contaminated ceramic insulators

    A computer model is developed which dynamically simulates the risk of flashover of contaminated insulators under real time change of the climatic environmental factors. From data of accumulation of contaminant, cleaning by rain, wetting by moisture, risk of flashover of a ceramic insulator is calculated which then gives the resultant risk of flashover of a system where several hundred number of ceramic insulators connected in parallel are subjected to the same degree of contamination severity and wetting.

  • Ceramic insulators for electrical and electronic applications

    The major developments in ceramic insulating materials have been made since World War I. These developments parallel the growth of the electrical and electronic industries. The pattern of these developments has been to tailor the properties of the ceramic insulators to specific requirements.

  • Criteria for the diagnostic of polluted ceramic insulators based on the leakage current monitoring technique

    Ceramic insulators installed in a 400 kV line located in a semidesertic area in Monterrey, Mexico have registered flashover caused during critical pollution (high amount of low solubility material) and wetting conditions (dense fog). In previous studies, the contaminant deposited on these insulators was chemically and electrically reproduced in the laboratory and the wetting conditions needed to cause the flashover at nominal voltage were also determined. To get more information, five different profiles of glass and porcelain insulators and several on-line leakage current monitors were installed in this line to determine the pollution accumulation process. Pollution tests were carried out in laboratory using the same insulator profiles in order to determine the leakage current patterns during critical conditions. The obtained values are being used to compare the performance of the insulators installed in the field with the purpose of providing preventive maintenance indicators. The maximum leakage current levels have been defined for the different profiles and a tighten relation between ESDD and leakage current has been obtained. The current levels have been used as a sign of alarm for the maintenance of this line during several years.

  • Detecting damages in outdoor non-ceramic insulators using near field microwave non-destructive testing

    This paper presents a novel near-field microwave nondestructive testing technique for defect detection in non- ceramic insulators (NCI). In this work, distribution class 33 kV NCI samples with no defects, air voids in silicone rubber and small metallic particles between the fiber core and shank were inspected. The microwave inspection system utilizes an open-ended rectangular waveguide sensor operating in the near-field at a frequency of 24 GHz. The used inspection system is simple, safe and relatively inexpensive. A data acquisition system was used to record the measured data. The results showed that all defects were repeatedly detected with high sensitivity. Line scans of the samples were obtained revealing the presence of different defects and their location. The technique also demonstrated ability to detect thickness variations in the silicone rubber shank.
