Harmonics are very harmful to electrical system and can cause consequences. For example, the presence of harmonics reduces the life of equipment. It is possible that the investment that you made in your motors & drives will not be realized if they are damaged and need to be placed before their expected life span. This causes very high unnecessary extra cost.

Harmonics cause heat to running devices, which cause stress on the cables and equipment. In the long term, this degrades an electrical system. The presence of harmonics will also mean that although you will get billed for the power that you are supplied, a large percentage of that power may be unusable. Harmonic mitigation is taking action to minimise the presence of harmonics in your electrical system and can achieve great cost savings.
