Analisis Gangguan Arus Hubung Singkat Pada Motor Induksi Tiga Phase Pada PT. Permata Hijau Palm Oleo Chemical KIM II Mabar

ABSTRACT


A 3-phase induction motor is used as an engine drive which is supplied by a 3-phase power source that requires protective equipment to secure the motor and motor circuit from disturbances that will occur when the motor is operated. ETAP Power Station 12.6.0 (Electrical Transient Analizer Program) is a program that can provide short circuit fault analysis. This study discusses the short circuit analysis of the electrical system of PT. Permata Hijau Palm Oleo Chemical KIM II MABAR with manual calculations and using the ETAP Power Station 12.6.0 program. The difference between the two calculation results is quite small, namely around 0.0035%. From the short circuit analysis, it is obtained a comparison of the safety capacity installed at the analyzed point of the contribution of the short circuit current calculated by manual and ETAP.
