ELECTRIC POWER QUALITY MEASUREMENT

The term power quality means maintaining sinusoidal wave of voltage at rated frequency without distortion. The prime objective is to transmit uninterrupted wave of voltage. This distortion is caused by the changing behavior of electric loads which causes changes in their waveforms even, these loads are called as non-linear loads. It also causes nonlinearities in the form of voltage sags, flickers, fluctuation, voltage dips. So these distortions adversely affect the current nature in the circuit. Usually it is also used to level up the quality of power than power provided by electric boards. In this we will study briefly the cases and also give adequate solutions obtained after a brief study on power measurement. Keywords— power quality, voltage sag, harmonic distortion, nonlinear load.
