How should non-linear loads be analyzed during calculations?

Non-linear loads should be analyzed for harmonic distortion because they create harmonics in the electrical system, which can affect the overall performance and efficiency of the power distribution. Non-linear loads, such as computers, variable speed drives, and certain types of lighting, do not draw current in a purely sinusoidal manner. Instead, they can distort the current waveform, leading to increased losses, overheating in conductors and equipment, and potentially disrupting sensitive electronic devices.

Evaluating these loads for harmonic distortion is crucial in load calculations for several reasons. It allows for the accurate sizing of equipment such as transformers and conductors to ensure they can handle the additional stress created by harmonics. Moreover, analyzing harmonic distortion helps in the design of power quality solutions, such as filters or mitigation strategies, to enhance system reliability and efficiency.

Considering the other options, disregarding non-linear loads would neglect an essential factor that can lead to significant system issues. Treating non-linear loads as linear loads would result in inaccurate calculations, potentially leading to undersized equipment and increased operational problems. Giving higher priority is a vague approach and does not directly address the specific impacts and calculations associated with harmonic distortion.
