Why is Harmonic Study and Analysis Important for Companies in Mexico | Carelabs
A good assumption for most consumers in Mexico is that the sinusoidal waveform voltage as generated is very good. In most areas, the supply voltage on power systems typically has much less than 1.0 percentage distorted. However, the disturbance level increases at the load end. For some type of loads, the current wave barely resembles like a sinusoidal wave.
Nonlinear loads like electronic converters can chop the supply waveform into arbitrary waveform. After the modern electronic equipment application in electrical systems, many engineers and consumers became very much concerned about the ability and quality of the system power supply to accommodate the harmonic disturbances.
Harmonic studies play an important role in characterizing and understanding the extent of harmonic problems. Harmonic studies are often performed when
Harmonic study and analysis provide a means to assess various possible control measures and their effectiveness under a range of conditions before implementing a final solution.
Harmonic disturbances are present on all electrical systems to some degree. Basically, we need to control the level of harmonics before they become a problem. There are three common causes of harmonic problems:
When harmonic distortion issue occurs, the basic controlling harmonics options are:
There are number of national and international level organizations working to come up with standard governing guidelines, best practices, and harmonic levels. The main aim of the standards is to give a common good practice for all work together to make sure the compatibility between end user equipment and the system.
The national/ international level standards & regulations that are governing harmonic distortion limits, including IEEE 519, IEC 61000-2-2, IEC 61000-3-2, IEC 61000-3-4, IEC 61000-3-6, NRS 048-2, and EN50160.
