Analysis of Harmonisa Impact on Transformer Distribution and Financial Losses

Understanding the Hidden Threats Behind Technological Progress

The development of technology has brought about significant changes in human life, from the use of computers and office equipment to household and industrial appliances. Most of these devices rely on electronic power components, which create non-linear loads. This non-linear burden is the source of harmonics, electric waves with a higher frequency than basic frequencies, which can disrupt the distribution system, including distribution transformers.

The Impact of Harmonics on Distribution Transformers

Increasing the use of energy saving lamps and power electronic equipment in the Multatuli Medan (BMM) business complex is a concrete example. Through direct measurement on the secondary transformer, it is found that the voltage and current flowing in it contains harmonica. Data analysis shows that an increase in load in the transformer is directly proportional to the increase in the total distortion of harmonisa (THDI) and energy loss.

Energy losses caused by harmonics in BMM are estimated to reach 52,925.91 KWH per year. This is equivalent to financial losses of Rp. 58,218,502.62 per year, or around 15.127% of the total electricity bill. This financial loss occurs because harmonics is not read by the KWH meter, so it is not recorded in the bill.

The Consequences of Harmonics on Distribution Transformers

The impact of harmonics on distribution transformers is not only limited to energy losses. Harmonisa can also cause:

*** Increased heating in transformers **: Harmonic current causes Eddy current and additional power loss, increasing the temperature of the transformer. This can reduce the life of the transformer and increase the risk of damage. *** Disorders of other equipment : Harmonisa can cause interference on sensitive electronic equipment, such as medical equipment and communication systems. *** Decreased power quality : Harmonisa causes distortion in the voltage waveform, which can interfere with operation of equipment that is sensitive to power quality.

The Importance of Minimizing Harmonics

It is essential to remember that the impact of harmonics is not always visible directly. However, significant financial losses can occur gradually. Therefore, efforts are needed to minimize harmonics in the distribution system. Some efforts that can be made include:

*** Use of Harmonisa Filter : Harmonic filter can be installed on a harmonic source or at certain points in the distribution system to absorb harmonisa and reduce distortion. *** System Design Optimization : A good system design can help minimize harmonics. This includes choosing equipment that has a low level of harmonica, and using cables that suits your needs. *** Increasing awareness : Increasing awareness about the impact of harmonics on the distribution system is very important to encourage prevention efforts.

Conclusion

In conclusion, harmonics is a hidden threat that can be financially and technically harmful. By understanding the impact of harmonics and applying preventive measures, we can maintain the reliability and efficiency of the electricity distribution system.
