The Use of a Single Tuned Filter as a Reduction of the Harmonic Effect of Television

Introduction

The use of non-linear loads, such as television, can cause harmonics in the electrical system. This harmonics can not only interfere with the performance of electrical equipment, but can also reduce the overall efficiency of the electric power system. The presence of harmonics in the electrical system can lead to a range of problems, including overheating of equipment, reduced lifespan of equipment, and even equipment failure. Therefore, it is essential to find a solution to reduce the harmonics produced by non-linear loads such as television.

The Problem of Harmonics in Electrical Systems

Harmonics are a type of distortion that occurs in electrical systems when non-linear loads, such as television, are connected to the system. These non-linear loads can cause the current and voltage waveforms to become distorted, leading to the presence of harmonics in the system. The harmonics can be in the form of voltage harmonics or current harmonics, and they can be measured in terms of their total harmonic distortion (THD).

The presence of harmonics in the electrical system can have a range of negative effects, including:

  • Overheating of equipment: Harmonics can cause equipment to overheat, leading to reduced lifespan and even equipment failure.
  • Reduced efficiency: Harmonics can reduce the efficiency of the electrical system, leading to increased energy consumption and costs.
  • Interference with other equipment: Harmonics can interfere with the performance of other equipment in the system, leading to reduced performance and reliability.

The Solution: Single Tuned Filter

One solution to reduce the harmonics produced by non-linear loads such as television is the use of a single tuned filter. A single tuned filter is a type of passive filter that is designed to reduce the level of harmonics in the electrical system. The filter works by using a combination of capacitance, inductance, and resistance to reduce the level of harmonics.

Simulation Method

In this study, the simulation method was used to analyze the effects of the single tuned filter on the reduction of harmonics from television. The simulation was conducted using a measuring instrument ** Power Q Plus Mi 2492 ** from the metrel. The measurement data obtained from the simulation showed that some of the Harmonisa Current (IHDI) orders from three television units of 21-inch tubes with 88 watts did not meet the standard ** IEC61000-3- 2 Class D **.

Results

The results of the simulation showed that the application of a single tuned filter with a capacitance value (C) 4,143 μF, inductance (L) 0.05 H, and resistance (R) 1.1 Ω was very effective in reducing the level of harmonics. The measurement results showed that ** Total Harmonic Distortion Voltage (THDV) ** reduced to 21.8% and ** Total Harmonic Distortion Current (THDI) ** reduced to 46.62%. Specifically, IHDI in the 5th order decreased to 0.160 A, in the 7th order to 0.078 A, the 9th order to 0.034 A, and the 15th order to 0.021 A. The IHDI value has now met the standards set by IEC61000-3-2 Class D.

Conclusion

The results of this study show that the application of a single tuned filter is a very effective solution to reduce the level of harmonics produced by non-linear loads such as television. The reduction in harmonics reaches 74.48% after the use of this filter, which shows that the single tuned filter is not only able to reduce harmonic levels, but can also improve the performance of the electricity system that is affected by non-linear loads.

Significance of the Study

This study has made a significant contribution in the development of harmonic control technology in the electricity system. With a better understanding of how single tuned filters work, it is expected that researchers and practitioners in the field of electricity can be more effective in designing a more efficient and sustainable system. It also opens the way for the use of similar technologies in other electrical equipment that can produce harmonics, thus contributing to energy efficiency and environmental sustainability.

Recommendations

Based on the results of this study, the following recommendations can be made:

  • The use of single tuned filters should be considered as a solution to reduce the level of harmonics produced by non-linear loads such as television.
  • Further research should be conducted to investigate the effectiveness of single tuned filters in reducing harmonics in other electrical equipment.
  • The development of more efficient and sustainable harmonic control technologies should be a priority in the field of electricity.

Limitations of the Study

This study has some limitations that should be noted. The study was conducted using a simulation method, which may not accurately reflect the real-world performance of the single tuned filter. Additionally, the study only investigated the effectiveness of the single tuned filter in reducing harmonics from television, and did not investigate its effectiveness in reducing harmonics from other electrical equipment.

Future Research Directions

Future research should focus on investigating the effectiveness of single tuned filters in reducing harmonics in other electrical equipment. Additionally, research should be conducted to develop more efficient and sustainable harmonic control technologies.
