Why Are Harmonic Analysis and Research Crucial for Hong Konger Businesses?
Harmonics are vital to a power system because they alter the quality of the electricity and how things function. Overheating produced by high harmonic levels may impair the lifespan of the equipment. Harmonics modify the pure sine wave generated by a perfect power source. Harmonic distortion complicates the operation and production of enterprises. The following are some commercial effects of harmonic distortion.
- Harmonics result in greater energy loss from components (Joule effect).
- When harmonics are present, the quantity of power subscribed to grows. As a result, costs rise, and consumer services become more expensive.
- Large apparatus with insufficient power source
- When the amount of distortion exceeds 10%, the lifespan of many components is reduced, resulting in a decline in output.
- Harmonics-caused peak currents trip obsolete equipment, resulting in output losses and a significant cost for the time required to bring the system back online.

Harmonics Result In:
Harmonics are created by loads that draw electricity in brief, sudden bursts rather than constantly. These pulses produce harmonic currents to flow as distorted current waves throughout the power system. Harmonics reduce the dependability and efficiency of industrial electricity. Up to 15% of nonlinear loads may be safely managed by most organizations’ electrical systems. If nonlinear loads account for more than 15% of the overall load, harmonic distortions may be hazardous. Therefore, it is vital to monitor harmonic levels to ensure they do not become excessive. Harmonic research and analysis are important for monitoring potential risks and causes. By doing so, it may be simpler to avoid harmonic-related issues at the design phase and less probable that undesirable outcomes would occur.
Analysis of Harmonics Technique:
Even if harmonic issues are unlikely, they must be analyzed immediately to ensure they are not grave. Here are the harmonic level’s stages:
- Obtaining a one-line electrical system diagram and identifying the available nonlinear loads is the initial stage.
- The emphasis of the graphic is on the location of the common connection (PCC).
- In system buses, emphasis is concentrated on distortion-prone plants.
- All information on harmonics has been gathered.
- Ask your utility provider for the PCC values that are in place. This contains the current and voltage harmonics allowed as well as the maximum and minimum short circuit fault levels.
- We do a simulated harmonic analysis using open-source software.
- Harmonically analyze the electrical system.
- Find the bus and PCC’s discrete and overall discrete current and voltage aberrations. It is necessary to generate a spectrum picture of the harmonic frequencies.
- Select the most effective harmonics control measures. Harmonic distortion exceeds acceptable levels.
- After implementing remedial measures, do a harmonic analysis.
