Current harmonic monitoring
15.11.3 Application
In order to maintain the power quality for better supply, harmonics in the system must be monitored.
Due to the nonlinear loads connected to the system, harmonics (apart from fundamental frequency
component) are generated and thereby the system voltage is distorted. Voltage distortion appears to
have a little effect on operation of nonlinear loads connected, either phase-to-phase or phase-to-
