COURSE OVERVIEW

 This practical and highly-interactive course includes various practical sessions and exercises.  Theory learnt will be applied using our state-of-the-art simulators. 

 

This course is designed to provide participants with a detailed and up-to-date overview of three -phase motors. It covers the induction motors, squirrel-cage rotors, pole-phase relationships, torque, rotor speed, slip and frequency; resistance, reactance, power factor, stator, rotor construction and air gap and operating features; wound-rotor motors, brushes, slip rings, synchronous motors, motor fields, characteristics and applications; pull-in torque, slipping pole, power factor, brushless motors and multispeed motors 

 

During this interactive course, participants will learn the consequent-pole, constant-horsepower, constant-torque, variable-torque & dual-voltage motors; care of stator, rotor windings and apply air gap, overload and single-phase operation; motor shaft currents, bearings and maintenance schedule; motor starters, limitations, full-voltage and across-the line starting; reducing starting current including primary and secondary resistance starters and maintenance; three phase motor controllers, multiple start-stop controls, across-the-line reversing starters, plugging control and jogging. 

Further, the course will also discuss the control surge, backspin and recognize alternators, characteristics, ratings and windings; three-phase alternators, air gap, slip rings, exciters including voltage regulation, load characteristics and effects; auxiliary generator systems, control equipment and transfer systems; safety switches, engine protection and prime movers and output control; power distribution systems, distribution voltages and heat loss; system grounding, overcurrent protection and ground relays including tripping; network protection.
