The Effect of a Mixture of Resin and SiO2 Epoxy Mixture on Leakage and Flashover Currents on the Polluted Condition of the Pin-Post Isolator

Introduction

The reliability of pin-post isolators is crucial in supporting electricity distribution, especially in areas where pollution and rain can significantly affect their performance. To maintain the functionality of these insulators, additional insulation materials are needed to coat them. In this study, a mixture of resin epoxy and silicon dioxide (SiO2) was used as the insulation material. The purpose of this study is to analyze the effect of this mixture on the leakage current value and flashover voltage on the insulator.

Background

Pin-post isolators are commonly used in the distribution network due to their reliability and effectiveness. However, their performance can decrease due to natural influences such as pollution and rain. To address this issue, researchers and engineers have been exploring various insulation materials to coat the isolators. In this study, a mixture of resin epoxy and SiO2 was used as the insulation material. The mixture consisted of Diglycidyl Ether of Bisphenol-A (DGEBA) as the basic material, metaphenylene diamine (MPDA) as the hardener, and SiO2 as the filler.

Methodology

The purpose of this study is to analyze the effect of the mixture of resin epoxy and SiO2 on the leakage current value and flashover voltage on the insulator. The results showed that the leakage current value in the insulator exposed to the NaCl solution ranged from 0.029 mA to 0.035 mA. When the insulator is also exposed to the NaCl solution in rainy conditions, the leakage current increases between 0.0572 mA to 0.6403 mA. In rain conditions without pollutants, leakage currents are in the range of 0.0550 mA to 0.3023 mA. In addition, in insulators contaminated with CaCO3, measured leakage currents range from 0.01984 mA to 0.0511 mA, while in the isolator contaminated with CaCO3 and in rainy conditions, leakage currents range from 0.0173 mA to 0.2426 mA.

Results

One of the significant findings of this study is the flashover voltage measurement. The resin and SiO2 epoxy layer can increase the flashover voltage up to 74.94 kV. This shows that the use of this mixture not only serves to protect the isolator from external influences, but also increases its performance in polluted conditions.

Discussion

This study provides an important insight into the effectiveness of the isolator coating in increasing the reliability of the electric power distribution system. With increased levels of pollution and various environmental factors that can affect the insulator, the use of resin epoxy and SiO2 coatings offers promising solutions. The use of these materials can reduce leakage currents, which are an indication of the decline in the performance of the insulator.

An increase in flashover voltage up to 74.94 kV shows that this coating can strengthen isolation and prevent flashover, which is a phenomenon where the electric current is jumping over the insulator and causing interference. This is very important, considering the flashover incidence can cause significant power outages and damage to the equipment.

Conclusion

In conclusion, this study demonstrates the effectiveness of the mixture of resin epoxy and SiO2 in increasing the reliability of the electric power distribution system. The use of this mixture can reduce leakage currents and increase flashover voltage, making it a promising solution for isolators in polluted conditions. This research can be a reference for the development of other isolation materials in the future.
