Harmonic Distortion

Harmonic Distortion is a crammed Harmonic Energy Surge

Total Harmonic Distortion

When a plant with high NLL runs at full load, it crams harmonics and active power in the power system, causing unacceptable energy surge wherein harmonic distortion is the ratio of harmonics to fundamental frequency (f1 -50Hz) component. Total harmonic distortion (THDv, voltage) and distortion factor are related terms defined by a ratio of square root sum of all high-frequency harmonic voltage-squares (v2, v3, v4, and so on) to fundamental frequency (v1) voltage.
