Aging chamber construction and insulator testing
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryOutdoor insulators are one of the main components in the electricity system, since they offer operational safety and operating efficiency of transmission systems of electrical power, and it is therefore of no surprise that these components must meet particularly high demands in terms of reliability.Outdoor insulators must fulfill some requirements to be reliable for years, including electrical, mechanical and chemical.
Complex stresses make the accurate lifetime estimation of solid insulators really difficult. Therefore, the aged insulators cause many failures along the power network lines.Predicting the long-time reliability is tough and to understand different mechanisms of ageing requires a long time so this has led to develop various tests known as “accelerated test”.An ageing chamber is used to perform this test, its a structure designed to stimulate the stability and reliability of insulators under multi stresses.
Decades of in-service performance have demonstrated that porcelain insulators show good mechanical and environmental aging performance; besides provide excellent resistance to material degradation caused by electrical stress and discharge activities. This project revolves around enhasing the functions of an ageing chamber by installing UV, Temperature and Moisture sensors in it.Polymeric insulators represent the major change in insulator design and materials in many years, and their advantages over porcelain and glass insulators have made them attractive to utilities.However, they are more susceptible to chemical degradation under the multiple stresses likely to be encountered in service; including stresses due to high operating voltages, UV rays and pollution contamination.
To verify the performance of chamber's efficiency and authentisity liquid and solid samples are produced and tested using these sensors.
Furthermore nanoparticles of oxide nature are added in samples to enhanse their breakdown stregnth and then the results are compared with pure insulators to determine the benefit of these composits.
The advanced ageing chamber will be utilized for observing treeing and tracking phenomenon of solid insulators as well.
Project ObjectivesBecause polymer insulators are a relatively new technology, their expected life is still unknown and is a subject of great interest to utilities. Therefore
- To calculate the expected life span of these insulators the functions of an ageing chamber will be enhansed by addition by installing UV, Temperature and Moisture sensors in it.
- To verify the authenticity of this chamber ageing tests will be performed on solids and liquids.

- Study the physical and chemical properties of these insulator types and draw comparisons.
- Verification of modivation through experimantal analysis.
- Comparison between Thermal behavior of four different types of nano composites and pure insulators through OFW method.
- To observe the phenomenon of treeing and tracking by performing breakdown voltage test on solid insulator sample.
- Publish the whole research done throughout the entire process in the form of research paper.

The first step before starting any project is to perform extensive research on the chosen topic and its modules .So we'll perform Literature review and gather maximum knowledge of high volatge insulators. (solid,liquid,gas) ageing chamber and various nano particles of oxide nature. Furthermore Literature review of breakdown volatges and various methods of performing High voltage tests.
Second Step
Once all the research is done the equipment will be purchased. To achieve this goal nano particles of Zinc, Nickel, Titanium and Aluminium oxide will be ordered in 50nm aswell as 100 nm size. For the ageing chamber enhansment UV light, Heat and Moister sensors of correct size and range will be purchased.
Third Step
Moving towards third step we'll enhanse the properties of an ageing chamber by the addition of components in it such as UV light, Heat and Moister sensors.This will provide accelerated ageing and help determine the expected lifespan of insulator samples being tested.
Step Four
Composite insulators will be composed with the help of addition of Zinc, Nickel, Titanium and Aluminium Oxides. Their properties will be analyzed through experimentation and then comparisons will be drawn between pure and composite insulators.
Step Five
Solid insulator samples will be studies for the analysis of Treeing and tracking phenomenon as well as breakdown stregnth.
Step Six
The final step is to sum up all the experimentation and studies in the form of a research paper.
