Since they have an effect on both the quality of the energy and the functionality of the equipment, harmonics are a crucial subject in a power system. High harmonic levels may lead to component overheating and shorten the life of the device. Harmonics distort pure sinusoidal waves produced by a perfect power source. Harmonic distortion limits a business’s ability to operate and produce. Here are a few harmonic distortion’s negative economic effects.

Increased component losses are a result of harmonics (Joule effect).
Harmonics lead to a rise in subscription power, which raises the cost of customer support.
High equipment size because of a weak power supply.
A variety of components have shorter lives and productivity declines when distortion levels are close to 10%.
Peak currents are introduced by harmonics, which causes output losses and significantly lengthens the turnaround time for system performance.

Harmonics Inspirations:

Harmonics are produced by nonlinear loads that draw current in erratic, short bursts. Because of the interruption caused by these pulses, harmonic currents can flow freely across the whole power system. Harmonics reduce the effectiveness and quality of electrical power in industrial applications. Most organizations are equipped with electrical infrastructure that can safely handle nonlinear loads up to 15%. If the proportion of nonlinear loads is more than 15%, negative harmonic distortions may develop. As a result, it is crucial to keep an eye on harmonic levels to make sure they stay within the permitted limits. As a result, a harmonic inquiry and analysis aid in the retention of information regarding prospective risks and their underlying causes, making it easier to avoid harmonic-related concerns throughout the design process and lowering the possibility of unintended consequences.

Harmonic Analysis Methodology:

Despite the remote possibility of harmonic problems, it is necessary to do a timely harmonic analysis to ensure that the harmonic levels are acceptable. The harmonic level progressions are as follows:

The first step is to get an electrical one-line diagram and recognize any potential nonlinear loads.
The picture draws attention to where the shared link is located (PCC).
Plants that are prone to distortion are highlighted in system buses.
Harmonics-related knowledge has been fully compiled.
Obtain from utility companies the PCC values that have been determined, along with the permitted maximum and lowest short circuit fault levels and current and voltage harmonics.
Using freely accessible software, a simulated harmonic analysis is performed.
Analyze the electrical system’s harmonics.
Find the bus and PCC’s discrete and overall discrete current and voltage aberrations.
Make a harmonic frequency spectrum.
Select effective harmonic control techniques. Harmonic distortion exceeds the permitted limits.
The harmonic analysis should be performed once mitigating factors have been considered.
