Harmonic is commonly generated in electricity system due to devices using Thyristor.
It can causes electricity accidents and interference in the system
Therefore, the application of filter facilities is essential to prevent the effect
of Harmonic in the system and use electricity more efficiently.
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 change of amplitude 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.
For example, an distorted wave form comprising sine wave type [50Hz] and 5th [250Hz] and 7th [350Hz]
wave form is analyzed as following :
ex ) Harmonic = Fundamental Wave + 5th Harmonic Part + 7th Harmonic Part

Samwha Creative TEchnology Provider 4. Special Capacitor Application 〉 Harmonic is commonly generated in electricity system due to devices using Thyristor. It can causes electricity accidents and interference in the system Therefore, the application of filter facilities is essential to prevent the effect of Harmonic in the 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 change of amplitude 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 higher than the fundamental frequency called harmonics and if the frequency lower called fractional harmonic wave or subharmonic.
