Introduction

Transformer oil is a crucial component in an electrical system, serving as an insulator and coolant. Over time, transformer oil can experience quality degradation, leading to a decrease in performance and even isolation failure. This isolation failure is often caused by the partial discharge phenomenon, which is the release of partial electric charges that occur in transformer oil. Recent research has shown that the addition of nanoparticles in transformer oil can be an effective solution to overcome the problem of partial discharge.

The Importance of Transformer Oil

Transformer oil is a vital component in an electrical system, responsible for several critical functions. It serves as an insulator, preventing the flow of electrical current between the transformer's windings and the surrounding environment. Additionally, transformer oil acts as a coolant, helping to regulate the temperature of the transformer and prevent overheating. However, over time, transformer oil can experience quality degradation, leading to a decrease in performance and even isolation failure.

The Problem of Partial Discharge

Partial discharge is a phenomenon that occurs in transformer oil, where partial electric charges are released. This can cause a range of problems, including insulation failure, overheating, and even transformer failure. Partial discharge is often caused by the presence of contaminants or defects in the transformer oil, which can lead to the breakdown of the oil's insulating properties.

The Role of Nanoparticles in Preventing Partial Discharge

Recent research has shown that the addition of nanoparticles in transformer oil can be an effective solution to overcome the problem of partial discharge. Nanoparticles have a broad surface and unique chemical properties, which allow them to interact with oil molecules and form protective layers on the surface of contaminant particles. This layer functions as a barrier that inhibits the release of electrical charges and prevents the emergence of partial discharge.

The Action Mechanism of Nanoparticles

The addition of nanoparticles to transformer oil can have a significant impact on the oil's insulating properties. When nanoparticles are added to the oil, they can interact with oil molecules and form protective layers on the surface of contaminant particles. This layer functions as a barrier that inhibits the release of electrical charges and prevents the emergence of partial discharge.

Research Results

This research was conducted by adding nanoparticles ZnO, SiO2, and CCl4 to used transformer oils with varying concentrations. The results show that the addition of nanoparticles, especially ZnO, significantly increases the initial voltage partial discharge. The higher the concentration of nanoparticles, the higher the initial voltage partial discharge. This shows that nanoparticles are effective in increasing the ability to insulation of transformer oil.

Advantages of ZnO Nanoparticles

Nanoparticles ZnO show better performance in increasing the initial voltage partial discharge than SiO2 and CCl4. At the highest concentration of 0.075%, ZnO was able to increase the initial voltage partial discharge up to 38.857%, from 4.11 KV before the addition to 6,772 kV after the addition of ZnO nanoparticles.

Conclusion

This study shows that the addition of nanoparticles, especially ZnO, in used transformer oil can be an effective solution to increase isolation resistance and prevent partial discharge. This can help increase reliability and age of transformers.

Benefits of Research

The results of this study provide important information for the electricity industry in an effort to increase the reliability of the electricity system. By using nanoparticle technology, it is expected to reduce the risk of transformer failure and increase the efficiency of the overall electrical system.

Future Research Directions

Future research should focus on the following areas:

Investigating the long-term effects of nanoparticle addition on transformer oil
Developing new nanoparticle materials with improved performance
Exploring the use of nanoparticles in other electrical systems, such as power transformers and switchgear

Conclusion

In conclusion, the addition of nanoparticles, especially ZnO, in used transformer oil can be an effective solution to increase isolation resistance and prevent partial discharge. This can help increase reliability and age of transformers. The results of this study provide important information for the electricity industry in an effort to increase the reliability of the electricity system.
