An intensive professional development training course on

Power Distribution Equipment

Optimisation of Uninterruptible Power Supply Systems,
Transformers and Circuit Breakers in a Modern Power Distribution System

Why Choose this Training Course?

Power distribution equipment which are reliable, safe and efficient are essential for an electrical installation. This Power Distribution Equipment training course includes the construction, operation and maintenance aspects of the equipment namely the transformers, circuit breakers, ring main unit, switches and protection devices. Safe operations are essential as they are protected by modern and sophisticated relays and protection devices. Power distribution can either be overhead or underground and auxiliary power is obtain by means of uninterruptible power supply.

Protection systems are installed to prevent faults from damaging electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system. Recent changes in technology together with changes in the manner in which utilities and industrial organisations operate, has greatly emphasized the development of integrated protection and control.

This AZTech training course will feature:

  • The construction and operations of transformers
  • The characteristics of circuit breakers
  • The importance and role of UPS and batteries
  • The types of maintenance
  • The functionalities of protection relays

What are the Goals?

By the end of this AZTech training course, participants will be able to:

  • Understand the major power distribution equipment
  • Determine the various types maintenance strategies
  • Explain the different types of circuit breakers
  • Analyse the characteristics of oil immersed transformers
  • Design a simple electrical power distribution incorporating the main power distribution equipment

Who is this Training Course for?

The training course will benefit the engineers, technicians and supervisors on the operations, functions of major renewable energy integration components. This AZTech course is suitable to a wide range of professionals but will greatly benefit:

  • Electrical engineers
  • Electrical supervisors
  • Power engineers
  • Managers in-charge of electrical installations
  • Project engineers

How will this Training Course be Presented?

This AZTech training course will utilise a variety of proven adult training techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes presentation and discussion of latest videos and technologies on smart grids and renewable energy.

Questions are encouraged throughout, particularly at the daily wrap up sessions. This provides opportunities for participants to discuss with the Presenter specific issues and, if possible, find appropriate solutions. Specific goals of each participant will be discussed to ensure that their needs are fulfilled whenever practicable.
