Analysis on the effect of harmonics filter applied to water treatment facilities

고조파 저감장치 현장적용 효과 분석

Recently, many water treatment facilities are operated by automatic control or by remote control. These high technology control systems require more stable power supply than before Badly most automatic control systems adopted in water treatment facilities are non-linear load which generates electrical harmonics inevitably. This study is intended to measure and analyze the electrical harmonics occurred at the chemicals control device which is inverter application circuit. and to show the effect of the harmonics filter.
