The detection and identification of faults on an electrical network has been and still is one of the problems facing Transmission and Distribution companies. The characteristics and operation of a network system are major considerations in creating or reducing the effects of electrical faults on the system. Effective modern protective systems are designed to sense faults and send a warning signal or initiate disconnection of the faulty system in an appropriate time. Delegates are encouraged to participate by active involvement in group discussions and sharing experiences.
What Is The Training Course Methodology?
This training methodology illustrates the concepts involved in the above areas through practical consideration of actual real-life problems, as well as explanation of concepts by experts in area using video projectors and computer aided case studies based on practical applications. Participants will solve their system problem, where the trainee’s try to apply the skills learnt with guidance from our specialized experts. ACAD will provide participants a comprehensive assessment on the problems solved using the skills acquired in the training course.
