AT33 IND™ Online Course

Course Number: 10032

This prerecorded introductory course presents the theory and application behind the latest techniques in evaluating the condition of low voltage 3 phase squirrel cage induction motors. This course explores more advanced measurements than the typical standard, venturing beyond winding insulation and insulation resistance to ground. Students will learn to easily and instinctively evaluate both of the motor’s insulation systems. This course also illustrates the measurement techniques in low voltage motor testing, the theories behind these techniques, and their proper application. Collection and interpretation of data taken with the ALL-TEST PRO 33 IND™ is also discussed.

Course Objectives

Successful completion of this course will enable students to:

• Understand “Improving Electrical Reliability”.
• Implement a deenergized testing program.
• Reduce the amount of catastrophic motor failures in their plant or facility.
• Provide insight on how to improve electrical reliability within their plant.
• Identify the components of the winding system, as well as factors that determine resistance (R), inductance (L), capacitance (C) and impedance (I/F).
• Describe how changes in R, L, Z, and I/F affect the winding system.
• Use the basic MCA™ instruments to manually measure Static 33 DYN Test.
• List the main types of failures associated with AC motors.
• Explain the various measurements used in MCA™.
• Evaluate a motor’s winding condition based on MCA™ measurements.
• Explain the purpose and features of the ALL-TEST PRO 33 IND™.
• Obtain data from a 3 phase AC motor using the AT33 IND™ (AUTO and manual modes).
• Evaluate the condition of an AC motor based on the measurements taken with the AT33 IND™.
