Impact Estimation of SMOG on Polymer & Ceramic Insulator in an Artificial Chamber
Insulators are core components for transmission of power supply and when failure in the insulator is caused they create huge power failures and these failures are mainly contributed by environmental factors as insulators are outdoor components. There are 2 types of insulators mainly used around the globe 1) Polymer insulator & 2) Ceramic Insulator.
Aging or stress test on insulators is to influence environmental aspects mainly SMOG, heat, rain, dust, and fog on high voltage insulators. Smog is a type of air pollution and is created by mixing Fog and smoke( NO2 or CO2 mainly).
what we are trying to do is that by creating Smog and various other environmental factors in an artificial chamber and then test both polymer insulators as well as ceramic insulators and analyze their aging process. The basic concept of this project is the comparison between ceramic insulators and polymer insulators.
This Final Year Project aims to check what impact SMOG has on Polymer and ceramic Insulator thus leading to contamination and Flashover issues and causing power failures. In the past experimental chambers have been designed to implicate aging tests on Polymer and ceramic. The Artificial chamber we have created will have 5 different types of artificial environments Raining, Cold, Hot, SMOG, and Dust.
The first step was developing the artificial chamber and then calibrating 5 different environmental settings, Once done Testing began on Polymer. This part consists of taking readings for all of the different environments e.g., rain, temperature, humidity, SMOG, and pH by using environmental data for the past 5 years of Pakistan for better and more accurate results. The Testing will let us know the different effects of the environment on Polymer and Ceramic insulators. After testing we will compare both Polymer and Ceramic insulators and check which insulator was impacted by the environmental stress more thus letting us know which insulator is more likely to be affected by Flashover and other problems.
Benifit of this FYP project are as it will tell us which of these both insulator are better suited for diffrent enviometal conditions if it is Polymer Insulator then :
| Factor | Ceramic | Polymer |
| WEIGHT | Heavy | 90% lighter than Ceramic |
| FRAGIBILITY | Fragile | Not Fragile |
| INSTALLATION | Risky and difficult | Easy |
| MAINTENANCE COST | High | Low |
| RESISTANCE TO FLASHOVERS | Low | High |
| HYDROPHOBICITY | Non-Hydrophobic | Hydrophobic |
| TENSILE STRENGTH | good | Excellent |
The project will be submitted in working condition. The whole body frame will be made up of steel, at which the bottom part of the frame will be made into a water tank completely sealed whereas the top part will be covered with acrylic so that it may be visible when performing the test on the insulator which will be at the center of the top tank hanging from the ceiling. artificial environmental conditions will be monitored and controlled via Arduino and different other sensors which all be will on a separate sensor panel board also made up of acrylic.
The final result of the project will give us which insulator (polymer and ceramic) was most affected by the artificial environmental conditions in our case we will gather the contamination residues from both insulators and compare which had the least contamination hence letting us prove which insulator is more reliable.
