Substation Bus Bar Switching Systems

Introduction

In the process of electricity generation, transmission and distribution, the voltage needs to be transformed from low to high or high to low as per different requirements. A switching station where this transformation takes place using transformers is known as a substation. The substations can either be air insulated (AIS) or gas insulated (GIS). It comprises of many electrical equipment and protection devices. These include the power transformer, high voltage circuit breakers, instrument transformers, dis-connectors, bus bars, and protection relays. The substation design is related to the bus bar arrangements as required by the utility companies. Each type of bus bar arrangement has got its own merits and characteristics. The purpose is to distribute electricity in the most optimal manner.

This Substation BusBar Switching Systems training course will highlight:

• The types and functions of a substation
• Common equipment installed in a substation
• Various type of busbar switching arrangements
• Characteristics and merits of each type of busbar arrangement
• Substation automation

Objectives

By the end of this  training course, participants will learn to:

• Identify the various types of substations and equipment
• Understand the benefits of each substation equipment
• Recognise the different types of busbars switching arrangements
• Optimising each type of busbar switching arrangement
• Assess the role of substation automation

Training Methodology

This Substation Bus Bar Switching Systems training course will ensure that participants will receive a thorough training on the subjects covered by the training course outline with the instructor utilising a variety of proven adult learning teaching and facilitation techniques. Each participant will receive a copy of the comprehensive training course notes. The presenter will outline and discuss the topics using computer displays, videos and power point presentation. The training course is designed to have an interactive format to maximize delegate participation. Questions and answers are encouraged throughout and at the daily sessions. Needs-Based case-studies and examples will be discussed in problem solving workshop sessions. This gives participants the opportunity to discuss with other delegates and the presenter their specific problems and appropriate solutions.
