Harmonics is a key aspect of a power system since they affect the quality of electricity and the performance of equipment. High harmonic levels may induce overheating of components, hence decreasing the device’s lifespan. An ideal power source produces harmonics that corrupt the pure sinusoidal wave. The production and operations of a corporation are hindered by harmonic distortion. The following are some business effects of harmonic distortion:

Harmonics create additional component losses (Joule effect).
The presence of harmonics increases subscription power and, thus, customer service costs.
Due to the reduction of the power supply, the equipment is oversized.
When the degree of distortion exceeds 10 percent, the lifespan of various components is diminished, resulting in a drop in productivity.
Harmonics introduce peak currents, resulting in output losses and a large cost to restore system performance.

Motives for Harmonics:

Nonlinear loads that consume current in abrupt, short bursts produce harmonics. This causes the transmission of harmonic currents throughout the electrical system. The presence of harmonics reduces power quality and efficiency in industrial environments. Most organizations have electrical systems that can withstand up to 15 percent non-linear loads safely. Negative harmonic distortions may be caused by non-linear loads above 15%. Therefore, it is crucial to monitor harmonic levels to ensure they do not exceed permissible limits. Thus, a harmonic investigation and analysis helps maintain awareness of potential risks and causes, so allowing the avoidance of harmonic-related concerns during the design phase and reducing the chance of unintended effects.

Methodologies for Harmonic Analysis:

Even if the likelihood of harmonic problems is low, a timely harmonic analysis must be undertaken to ensure that harmonic levels are appropriate. These are the level progressions in harmonic music:

Obtaining a one-line electrical diagram and detecting potential nonlinear loads is the first step.
The illustration highlights the position of the common coupler (PCC).
In system buses, distortion-prone components are given priority.
All harmonics-related data has been collected.
Obtain from utility companies the established PCC values, such as the maximum and lowest short circuit fault levels and the allowable current and voltage harmonics.
A simulated harmonic analysis is performed using freely available tools.
Perform an analysis on the system’s harmonics.
Calculate the current and voltage total and discrete distortions at the buses and PCC.
Create a frequency spectrum of harmonics.
Select proper harmonic control methods. Harmonic distortion reaches allowable values.
After mitigating factors have been considered, the harmonic analysis must be repeated.
