Analysis Of The Effect Of Temperature On The Performance Of The TM 5 Transformer On The Paya Paya Sand PLTG

Introduction

The transformer plays a crucial role in the electric power system, serving as a vital component in changing the voltage level of electric current for efficient distribution. Maintaining the performance and reliability of transformers is essential to prevent failures that can have a significant impact on the entire system. One way to prevent such failures is through periodic monitoring and maintenance of the transformer's condition.

The Importance of Insulator Oil in Transformers

Inside the transformer, there is an insulator oil that serves two primary purposes: preventing electricity leakage and maintaining a stable transformer temperature. However, the quality of this insulator oil can be influenced by various factors, including temperature. Under certain circumstances, the insulator oil can contain solid particles, gas bubbles, and dissolved gases that can affect transformer performance. Therefore, it is essential to analyze the quality of this insulator oil, one of which is through testing Dissolved Gas Analysis (DGA) and translucent voltage testing.

Dissolved Gas Analysis (DGA) and Translucent Voltage Testing

Testing DGA will identify the presence of dissolved gases such as hydrogen (H2), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), Ethylene (C2H4), Ethhana (C2H6), and acetylene (C2H2). The existence of these gases can provide an indication of the condition of the insulator oil. While the translucent voltage test aims to measure the dielectric strength of the insulator oil. A decrease in the strength of the translucent voltage periodically can be an indicator that the quality of oil has decreased.

The Effect of Temperature on Transformer Performance

From the analysis conducted on the TM 5 transformer on Paya Paya Pasir PLTG, the data shows that there is an increase in the dissolved gas content along with the increase in temperature. This indicates that high temperatures can cause an increase in chemical reactions in oil, which leads to the formation of unwanted dissolved gases. When the temperature reaches a certain point, these dissolved gases can cause the formation of gas bubbles which in turn can damage isolation and reduce the performance of the transformer.

The Relationship Between Temperature and Transformer Performance

In addition, increased temperature can also affect the viscosity of oil. High viscosity will reduce the ability of oil to cool the transformer and inhibit the circulation of oil, so that it can cause overheating. This shows a strong relationship between the temperature and performance of the transformer, where high temperatures can be a cause of operational failure.

Maintaining Transformer Reliability and Performance

In an effort to maintain the reliability and performance of the transformer, it is essential to conduct routine testing and monitoring the temperature and quality of the insulator oil. Efficient cooling system implementation and good maintenance can help in reducing the risk of failure. With these anticipatory steps, it is expected that the continuity of the electric power system can be maintained, so that the transformer can function optimally.

Conclusion

Overall, the effect of temperature on the performance of the TM 5 transformer on the Paya Sand PLTG shows how important it is to understand the characteristics and operational conditions of the transformer. By maintaining and monitoring the temperature and quality of the insulator oil regularly, we can prevent damage that can interfere with the continuity of electricity supply.
