              Electrical Distribution Equipment Operation & Maintenance 




Global economics is rapidly changing methodology in the Distribution of Electricity throughout the world. Many Distribution Electricity Utilities have changed from State Ownership to Private Ownership and the trend is increasing worldwide.


A first step for all concerned is to ensure that decision-making personnel possess sufficient up-to-date knowledge of distribution system behaviour and modern distribution management technology.




To ensure delegates develop their existing knowledge and are acquainted with latest developments in Distribution Management Technology.  In addition that the principles can be appropriately applied in every day work to improve their personal effectiveness and efficiency throughout the whole enterprise.






The Seminar is designed for Utility Managers, Engineers and Technicians who are responsible for the:-


  • Design, Specification and Project Management
  • Operation and Maintenance
  • System Operation and Control
  • Overall Enterprise Management


of Distribution Networks, who may require to refresh their knowledge and acquaint themselves with latest developments.


It is also of benefit to non-utility personnel who require a good understanding of distribution systems due to employment in related activities, e.g. government agencies, loan agencies etc. Design, Marketing and Project Management Personnel from manufacturers of  Distribution Equipment should also benefit greatly from the seminar.




The latest educational methods and strategies are employed. The course is designed to maximise delegate participation. From the outset, the goals of each participant are discussed to ensure needs are fulfilled as far as possible. Questions and Answers are encourages throughout and at the daily wrap-up sessions.
