What is the consequence of ignoring harmonics in system design?

Ignoring harmonics in system design can significantly impact the performance and reliability of electrical systems. When harmonics are present, they introduce distortions in the current and voltage waveforms. This can lead to overheating in electrical equipment, as they may not be designed to handle the additional heat generated by these distortions. As a consequence, the lifespan of equipment can be greatly reduced.

Additionally, harmonics can cause issues such as increased losses in transformers, motors, and other electrical devices, which can result in higher operational costs. These factors collectively mean that overlooking harmonics during the design phase can lead to more frequent repairs and replacements, increasing the overall cost of the electrical system over time.

Addressing harmonics through proper design and mitigation strategies helps ensure that equipment operates efficiently and reliably, thus preserving its lifespan and reducing maintenance costs.
