 - Application
Harmonics is commonly generated in electricity system due to devices using Thyristor. It can causes electricity accidents and interference in Power system. Therefore, the application of filter facilities is essential to prevent the effect of Harmonics in Power system and use electricity more efficiently.

 - What is harmonic
Cyclic distortion wave is expressed as the sum of sine wave [50Hz], the integral number frequency and major sine wave, integral number [50Hz] frequency. This integral number frequency is called harmonic wave and according to the amplitude change and phase, wave form is changed resulting in synthetic distortion. Combined distortion wave is manifested in distorted sine wave form. This form can be analyzed into one fundamental wave [50Hz] which has random cycle and major sine wave which has integral number frequency or subharmonic frequency. If the frequency of it is higher than the fundamental frequency, it is called harmonics and if the frequency of it is lower, it is called fractional harmonic wave or subharmonic.
