Course Details

Electrical Motor Current Signature Analysis

Dubai, UAE
From Date: 07-Aug-2023   
To Date: 11-Aug-2023
5 days

This course will cover mainly AC motors ranging from low voltage to medium voltage induction motors. Motor is not given its due importance in the industry generally and some of the motors are being rewound after one or two failure and another without considering loss of efficiency due to Motor efficiencies are not measured or tracked. Reliability is not given its due consideration. This course will have in depth discussions on Motor Management.


The technicians and maintenance staff will be able to comprehend the construction, operations, function of major electrical power distribution system . This will enable them to carry out effective maintenance, installation and selection activities.

This training course is suitable to a wide range of professionals but will greatly benefit:

?         Electrical  Engineers

?         Electrical  Supervisors

?         Maintenance Technicians

?         Managers in-charge of Electrical  Installations
