Introduction

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 obtained by means of uninterruptible power supply.

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

This 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?

• 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?

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