EE0468 : Condition Monitoring of Motors and Transformers

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 the concept of Motor and Distribution Transformer Protection (Theoretical & Practical Aspects). It covers the need for motor protection, basic operation of motors and their structure; the common types of motor faults, damages and the principles of motor protection; the causes of thermal overload and the measures to protect the motor from it; the earth fault protection and rectifying earth faults; the causes, impacts and preventive measures of short circuits; setting up short circuit protection and conducting tests; configuring and testing a long start protection relay and unbalance protection; and setting up and testing blocked rotor protection relay and load loss protection relay.
During this interactive course, participants will learn the role of RTD sensors in motor protection; installing, using and troubleshooting RTD sensors; the implications of the number of starts on motor operation and longevity; configuring and testing start controls; the basic operation and structure of transformers, common types of faults and the principles of transformer protection; the causes and impacts of voltage issues in transformers and how to protect against them; setting up and testing voltage protection, overcurrent protection, protection relays and REF relay; the directional earth fault and definitional protection mechanisms, their necessity and implementation; the restricted earth fault (REF) protection, when it is used and how it is set up; the methods and best practices of CT and PT testing; and the motor and transformer operation and maintenance.
