Transformer Life Failure Prediction Methods Course
Introduction:
Elevated energy is what electricity is. Power transformers are a necessary part of working at generating stations and electrical substations. The regulations governing power transformers and their applications, as well as the requirements for testing, maintenance, and troubleshooting transformer failures, must all be understood by staff managers, administrators, engineers, and technicians. They also need to be able to comprehend the protection system of power transformers. The power companies are required to provide customers with electricity at the lowest feasible cost while maintaining safety standards.
Course Objectives:
By the end of the training, participants will be able to:
- Develop a thorough understanding of electrical power transformer rules and their application
- Understand individual responsibilities for power transformers in substations
- Learn the detailed procedures for testing of power transformers standards
- Understand the power transformer failure analysis & troubleshooting
- Learn requirements for the maintenance of power & distribution transformers
- Develop an understanding of the role of switchgear and associated protection in transformers
- Identify key issues for the improvement of their company’s power transformers’ operation
Who Should Attend?
This course is intended for Engineers and Technicians from Electrical Power Utilities Companies, Manufactures, and Distributors of Power Transformers, Engineering professionals in Petrochemical Companies, and Commercial Buildings. Participants need no specific requirements other than a basic understanding of Electricity and Magnetism and knowledge of nature and operation of Power supply and distribution system.
