Harmonics are a crucial topic in a power system because they have an impact on both the quality of the energy and how effectively the equipment functions. High harmonic levels may cause component overheating and shorten the lifespan of the device. The pure sinusoidal wave produced by a perfect power source is twisted by harmonics. Harmonic distortion makes it difficult for a business to generate and manage its operations. Here are a few financial impacts of harmonic distortion.

Harmonics cause extra component losses (joule effect).
Harmonics increase subscription power, which increases customer service expenses.
Oversized equipment as a result of the diminished power supply
When the distortion level approaches 10%, several components’ lifespans are reduced, and productivity is also affected.
Harmonics cause output losses and peak currents to be introduced, which considerably extends the time needed to restore system performance.

Harmonic Motives:

Nonlinear loads that draw current in irregular, brief bursts cause harmonics to occur. Harmonic currents can travel across the whole power system because these pulses cause the current waves they generate to be disrupted. Harmonics lower the quality and efficiency of electricity in industrial settings. The electrical infrastructure of most businesses is capable of securely handling loads that are up to 15% non-linear.

If non-linear loads approach 15%, negative harmonic distortions may happen. In order to ensure that harmonic levels stay within the authorized ranges, it is important to continuously check them. In order to avoid harmonic-related issues throughout the design process and lessen the possibility of unintended effects, a harmonic inquiry and analysis helps to keep knowledge of potential dangers and their core causes.

Method for Harmonic Analysis:

Even if harmonic issues are unlikely, it is nevertheless important to perform a timely harmonic analysis to make sure the harmonic levels are adequate. The following are the harmonic level progressions:

Obtaining an electrical one-line diagram and identifying any potential nonlinear loads are the first two steps.
The image emphasizes where the common link is located (PCC).
System buses draw attention to plants that are susceptible to distortion.
All information pertaining to harmonics has been acquired.
Obtain the PCC values, such as the highest and lowest levels of short circuit failures and the allowable current and voltage harmonics, from the utility companies.
Using freely accessible software, a simulated harmonic analysis is performed.
Analyze the harmonics of the electrical system.
Find the current and voltage discrete and total discrete distortions at the buses and PCC.
Create a spectrum of harmonic frequencies.
Select effective harmonic control methods. Harmonic distortion goes above permitted levels.
Repeat the harmonic analysis once mitigating factors have been taken into account.
