PROTEKSI MOTOR INDUKSI TIGA FASA TERHADAP EMPAT JENIS GANGGUAN

Abstract

Abstract: The protection of three-phase induction motor against four types of disturbance. Generally, the installation of three-phase motor only uses protection system of fuse and MCB. However, the usage of fuse and MCB is still limited; due to the availability of another system that cover much more disturbances. This research sets out to develop the protection of three-phase induction motor by using computerization and electro-mechanics. It used experimental method with the stages as follows (1) designing protection circuit, (2) testing the circuit, (3) analyzing the result, and (4) redesigning the circuit if necessary. The outcome of this research is the protection tools of induction motor installation, which is able to operate over various types of disturbance.
