1. General
The proliferation of nonlinear loads such as static power converters and arc furnaces results in variety of
undesirable phenomena in the operation of power systems.
The most important among these are harmonic contamination, increased reactive power demand and
power system voltage fluctuations.
Harmonic currents increase power systems losses, excessive heating in rotating machinery, can create
significant interference with the power line communication.
The harmonic is a growing problem for both electricity suppliers and consumers.
2. Problems of Harmonic
•Malfunction of precision control
