With this online course, you will become a master in electrical maintenance. Do you want to learn about the types, causes, effects and corrections of misalignment in machinery? Then sign up for free today. You will study the various tools commonly used to correct misalignment and see the methods to remove bearings in different types of machinery. This course also explains how to check or measure air gap dimensions before starting the bearing of a large motor. See how to overhaul an induction motor and service a universal motor.

The material covers all aspects of testing, monitoring, fixing, and replacing elements of an electrical system. It takes you through basic electrical principles such as the causes of short circuits and common locations of earth faults. Learn about the working principles of meggers and the effect of meggering at a higher voltage. Discuss the significance of and precautions for checking the insulation resistance value of electrical machines. Then study the procedures for drying out electrical windings. This course also focuses on the classification of electrical insulation based on the temperature stability of the materials used.

You conclude by learning how to solve practical problems like failure of exciter voltage, alternators not accepting the loads, overheating of the motor, operational issues in AC motors and troubleshooting a DC regulated power supply. Furthermore, active and passive safety systems are discussed with examples. The course explains the procedures to isolate electrical equipment to work safely and the precautions to prevent any conductor from being electrically charged when it is being worked on. This course provides the learner with a thorough understanding of the methods of diagnosing, troubleshooting, and repairing industrial equipment.
