Harmonics is an important aspect of a power system since it affects power quality and equipment operation. High harmonic levels may cause component overheating, hence reducing the device’s lifespan. Harmonics corrupt the pure sinusoidal wave produced by a perfect power source. Harmonic distortion hampers a company’s production and operations. Here are some of the economic effects of harmonic distortion.

Harmonics create additional component losses (Joule effect).
The presence of harmonics causes an increase in subscribed power and, consequently, a rise in customer service costs.
Equipment oversizing due to diminished power supply
When the amount of distortion reaches 10 percent, the lifespan of various components is shortened, resulting in a decline in production.
Harmonics create peak currents that result in the annoyance tripping of obsolete technology units, resulting in production losses and a prohibitive cost to restore system performance.

Harmonics Lead to:

Harmonics are created by nonlinear loads that draw current in abrupt, short bursts. These pulses produce distorted current waves, resulting in the transmission of harmonic currents across the electrical grid. The presence of harmonics in industrial environments degrades power quality and efficiency. Most businesses have electrical systems that can safely support up to fifteen percent nonlinear loads. If non-linear loads exceed 15%, negative harmonic distortions may arise. Therefore, it is necessary to monitor harmonic levels to ensure they do not exceed permissible limits. Thus, a harmonic study and analysis assists in maintaining awareness of potential risks and causes, so allowing the avoidance of harmonic-related concerns throughout the design process and reducing the chance of unintended effects.

Harmonic Analysis Procedure:

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

The initial step involves obtaining an electrical one-line diagram and identifying available nonlinear loads.
The image emphasizes the position of the common connection (PCC (Point of Common Coupling)).
Plants sensitive to system bus distortion have been identified.
All harmonics-related information has been acquired.
Obtain from utility companies the established PCC values, which include the maximum and lowest short circuit fault levels and the allowable current and voltage harmonics.
An examination of simulated harmonics is performed using open-source software.
Analyze the electrical system’s harmonics.
Calculate the global and discrete voltage and current distortions at the buses and PCC.
Draw the harmonic frequency spectrum.
Select appropriate harmonic control measures Harmonic distortion reaches allowable values.
After mitigating factors have been considered, repeat the harmonic analysis.
