This document is a handbook on harmonic mitigation solutions, covering the origin and consequences of harmonics, the benefits of harmonic mitigation, and Schneider Electric's solutions. The guide aims to help readers understand the basics and effects of harmonics, interpret applicable standards and regulations, and provide a comprehensive offer of harmonic mitigation solutions from Schneider Electric. Readers can adopt the best available solutions based on optimum economical solution related to Capex and Opex, in addition to improved energy.
The guide introduces the basics of harmonics, their origins, and the impact on electrical systems, distinguishing linear and non‑linear loads. It outlines standards, regulations, and the economic consequences of harmonic distortion.
It then presents Schneider Electric's product portfolio and solution approaches for new installations, existing plants, and specific applications such as variable speed drives, highlighting potential Capex/Opex savings and improved equipment lifetime.
| Capex/Opex reduction | Up to 25% |
|---|---|
| Total harmonic distortion (THDi) | 35% |
| Line rms current | 60 A |
| Total power | 202 kW |
It can achieve up to 25% reduction in capital and operating expenses and improve equipment lifetime.
Uninterruptible Power Supplies, office equipment such as PCs, printers, servers, and variable speed drives are non‑linear loads.
The example shows a total harmonic distortion (THDi) of 35%.
A line rms current of 60 A is used in the sizing examples.
