Study and protection the basic faults for medium voltage motors

Abstract

Medium voltage (MV) motors play a critical role in industrial applications, where reliability and operational continuity are essential. These motors are subject to various electrical and mechanical faults that can lead to significant downtime, equipment damage, and safety hazards if not properly addressed. This work aims to provide a comprehensive understanding of MV motors uses in LAFARGEHOLCIM company located on the Hammam Dallaa, Msila. In addition, an investigations of the fundamental and methods of protection fault focuses on the types of faults commonly encountered, such as line to line faults, ground faults, overcurrent, also thermal overloads. Furthermore, an analyzing protection strategies including the protective relays, circuit breakers, thermal sensors and differential protection schemes uses in industrial environments.
