Introduction

Liquid insulation oil is a crucial component in the transformer system, playing a vital role in both insulation and cooling. To function optimally, the oil must possess a specific dielectric strength, also known as the breakdown voltage, which is influenced by various factors such as the presence of gas bubbles, the level of purity of the oil, and its age. In this study, we aim to evaluate the potential of rubber seed oil as an alternative to liquid insulation oil, focusing on its dielectric strength and performance under different temperature conditions.

Background

Liquid insulation oil is a critical component in transformer systems, responsible for both insulation and cooling. The dielectric strength of the oil, also known as the breakdown voltage, is a crucial parameter that determines its suitability for use in transformer applications. Various factors can influence the dielectric strength of the oil, including the presence of gas bubbles, the level of purity, and its age. In recent years, there has been a growing interest in exploring alternative materials for liquid insulation oil, driven by concerns over the environmental impact and cost of traditional oil-based insulation materials.

Methodology

In this study, we conducted a comprehensive analysis of rubber seed oil as an alternative to liquid insulation oil. The test was carried out using standard ball electrodes and observing temperature variations. The temperature variation was a critical factor in this study, as oil temperature often increases, especially when the transformer operates at high loads. We compared the performance of rubber seed oil with other vegetable oils, including sunflower seed oil, grapeseed oil, and olive oil.

Results

The test results showed that the dielectric strength of rubber seed oil increased with an increase in temperature. At 28.3 °C, the dielectric strength was recorded at 28.02 kV, while at 60 °C it increased to 33.9 kV. However, when the temperature reached 80 °C, a significant decrease in dielectric strength occurred, down to 27.1 kV. When compared with other vegetable oils, rubber seed oil showed good performance, with the highest dielectric strength at 28.3 °C and 40 °C, which were 28.02 kV and 32.22 kV, respectively. However, at 60 °C and 80 °C, olive oil had the highest dielectric strength, 43.09 kV and 41.36 kV, respectively.

Discussion

The results of this study suggest that rubber seed oil shows promising potential as an alternative to liquid insulation oil, especially at low to medium temperatures. However, a significant decrease in dielectric strength at high temperatures indicates that this oil may not be ideal for applications where operating temperatures can increase significantly. Conversely, olive oil remains superior in terms of dielectric strength at high temperatures, making it a better choice for applications where operating temperatures can increase significantly.

Conclusion

In conclusion, this study provides valuable insights into the potential of rubber seed oil as an alternative to liquid insulation oil. While rubber seed oil shows promising performance at low to medium temperatures, its significant decrease in dielectric strength at high temperatures raises concerns over its suitability for use in transformer applications. However, the use of rubber seed oil as an alternative is worth considering, especially in applications that are not too burdening temperature. Further research and long-term testing are needed to confirm the durability and performance of rubber seed oil in real conditions.
