• Design coordination of maintenance activities and maintaining system safety
• Apply air and gas insulated switchgear operations and maintenance
• Explain the various types of protective relays
• Analyse troubleshooting and repair of high voltage switchgears

The technicians and maintenance staff will be able to comprehend the types, construction, operations, function of transformers. This will enable them to carry out effective maintenance activities.

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

• Electrical engineers
• Maintenance technicians
• Electrical supervisors
• Engineering professionals
• Managers of the electrical engineering department

The goals of each participant are discussed to ensure their needs are fulfilled, as far as possible. Questions are encouraged throughout, particularly at the daily wrap up sessions. Each seminar participant will receive a copy of the comprehensive seminar notes. The presenter will outline and discuss the topics using computer displays, video clips and PowerPoint presentation. The seminar is designed to have an interactive format to maximize delegate participation.
