What is Harmonic Distortion?

Harmonic distortion occurs when unwanted frequencies are introduced into an electrical system, typically caused by non-linear loads such as variable frequency drives (VFDs), UPS systems, LED lighting, and certain industrial machinery. These harmonics distort the voltage and current waveforms, leading to reduced power quality.

Why It Matters

Left unchecked, harmonics can:

Common Causes of Harmonics

How to Measure Harmonics

Using a power quality analyzer, engineers can measure Total Harmonic Distortion (THD) in a system. A THD value above recommended limits (as per IEEE 519 standards) indicates the need for mitigation.
