Hands-On Electrical Testing and Maintenance

Course Description

This Hands-On course will teach you how to prioritize your electrical maintenance strategy, stretch your electrical maintenance budget and at the same time maximize the life and condition of your equipment.

Cost-effective electrical preventive maintenance is the best way to reducing accidents, saving lives, and avoiding costly breakdowns and work stoppages. Our Electrical Testing and Maintenance course is an in-depth examination of electrical testing and predictive maintenance methods and teaches how to maximize the effectiveness of your electrical maintenance investment. Our course introduces students to NETA (North Amercian Electrical Testing Association) "Standard for Maintenance Testing Specifications" and NFPA 70b, "Recommended Practices For Electrical Equipment Maintenance".

These standards apply to preventive maintenance for electrical, electronic, and communication systems and equipment installed in industrial, commercial and institutional power systems.

This course will alert electrical maintenance personnel in utility, industrial, commercial and institutional facilities to the latest North American Electrical Maintenance and Testing Standards and Specifications that cover the suggested field tests and inspections that are available to assess the suitability for continued service and reliability of electrical power distribution equipment and systems. The purpose of NETA and NFPA 70b testing and maintenance specifications is to assure that tested electrical equipment and systems are operational and within applicable standards and manufacturer's tolerances and that the equipment and systems are suitable for continued service.

This course will also deal with the important subject of troubleshooting electrical systems and choosing the proper preventive maintenance testing equipment and procedures.

Students Will Learn

Learn How to design and implement a cost-effective "Recession-Friendly" electrical maintenance program.
Learn the essential procedures for the safe operation, repair, testing, and maintenance of major power equipment.
Learn how to establish what electrical maintenance work can be done in-house and what must be contracted out.
And more...

Target Audience
