The Influence of the Angle of Installation and the Intensity of Rain on the Emergence of Partial Discharge in the Porcelain Plate Isolator: Proof and Wet

Introduction

In the electric power system, the insulator plays a vital role in separating the voltage with the non-voltage. Porcelain plate isolators, which are often assembled into the isolator chain, are one of the main choices in Indonesia. However, over time, the isolator is vulnerable to the buildup of pollutants and rain exposure, which has the potential to trigger phenomena * partial discharge * (PD). This phenomenon can cause damage to insulators, operational disorders, and even power outages. The emergence of PD in the porcelain plate isolator is a critical issue that needs to be addressed to ensure the reliability and efficiency of the electric power system.

The Importance of Understanding the Effect of Installation Angle and Rain Intensity on PD

The installation angle and rain intensity are two critical factors that can influence the emergence of PD in the porcelain plate isolator. The installation angle can affect the distribution of pollutants and water on the surface of the insulator, while the rain intensity can impact the amount of water that accumulates on the surface of the insulator. Understanding the effect of these factors on PD is essential to develop strategies for preventing or mitigating the damage caused by PD.

Research Methods

This study examines the effect of the installation angle and rain intensity on the emergence of PD in the porcelain plate isolator using the experimental method. The experiments were carried out by testing porcelain plate insulators at various installation angles, ranging from suspension positions (0 °) to tension position (90 °). The condition of the isolator was varied, including:

*** Dry Conditions ***: The insulator is clean and dry. *** Proof Conditions ***: The insulator is given a layer of NaCl and CaCO3 pollutants. *** Wet Conditions ***: The insulator is given artificial rain with a certain intensity.

The test was carried out by supplying the voltage to the insulator until PD occurs. The voltage value needed to trigger PD was then recorded and analyzed.

Results and Analysis

The results showed that the installation angle had a significant influence on the emergence of PD. In dry and proof of NaCl conditions, the PD voltage decreased as the horizontal angle increased. In wet conditions with NaCl, the same pattern was visible, with the PD voltage decreasing as the horizontal angle increased. However, in wet conditions with CaCO3, the pattern was slightly different. PD voltage tended to decrease from angle 0 ° to 45 °, then increase again at angle of 60 ° and 90 °.

This difference in pattern shows that the type of pollutants and wet conditions have a complex influence on PD characteristics. The results of this study provide some important implications for the operation of the electric power system.

Implications and Recommendations

The results of this study provide some important implications for the operation of the electric power system:

*** The Importance of Selecting the Right Installation Angle ***: The insulator installation angle must consider the level of pollutants and the intensity of rain at the installation location. *** It is Necessary to Do Routine Maintenance ***: Cleaning of isolators regularly and the use of anti-police methods can minimize the risk of PD. *** The Development of More Durable Isolator Material ***: Development of isolator material that is resistant to pollutants and rainwater can increase the reliability of the electric power system.

Opportunities for Further Research

This research opens opportunities for further research, such as:

*** Analyzing the Effect of Pollutant Types and Rain Intensity on PD in Various Types of Insulators ***: This study can be extended to analyze the effect of different types of pollutants and rain intensity on PD in various types of insulators. *** Developing a Simulation Model to Predict the Emergence of PD in the Isolator ***: A simulation model can be developed to predict the emergence of PD in the isolator based on the installation angle and rain intensity. *** Developing an Early Detection Method PD to Prevent Damage to the Isolator ***: An early detection method can be developed to prevent damage to the isolator by detecting the emergence of PD.

Conclusion

By understanding the effect of the angle of installation and intensity of rain on PD in the porcelain plate isolator, the electric power system can be operated more securely, efficiently, and reliably. The results of this study provide some important implications for the operation of the electric power system, and opportunities for further research are also identified.
