This five-day, eight hours training has been instructed consistently since 1981 and provides maintenance personnel responsible for electrical systems with predictive and preventative testing and maintenance skills. It is taught in one of our mobile training centers set up specifically for maintaining and testing electrical equipment.
Participants will be involved in a combination of classroom and hands-on labs which they can then apply to their own testing and maintenance programs.
This course is 75% hands on and will teach your students to inspect, test, troubleshoot and maintain common electrical equipment. Your equipment will also be incorporated into the training. If your equipment is not available for practical work then the instructor will explain the testing required for your equipment including examples and simple demonstrations.
Our instructors have extensive experience with substation and plant electrical equipment and can address a broad range of systems.
