Overview ?

Introduction

The electrical designer, installer and maintenance team are all expected to provide an installation that is safe, cost effective and reliable throughout its lifetime.

The course begins with the fundamental principles that always apply to ensure safety, the course then progresses through basic design procedures, inspection, testing and maintenance requirements, concluding with a review of power quality problems that affect the reliability of an installation where high technology interfaces with a supply.

The seminar will provide an understanding of:

The initial assessment of an installation prior to the design
Selection of protective devices
Cable sizing and installation
Inspection and testing procedures
The maintenance requirements

Seminar Objectives

The delegate will gain detailed appreciation of:

The safety factors required by national and international standards
The functional considerations that a designer has to take into account
How new technology can impact on the design particularly power quality
Safety requirements during installation, inspection and testing
Inspection and testing techniques that affect the maintenance requirements
How to improve productivity by improving the reliability of an installation

Training Methodology

The seminar is conducted as modular lectures with encouragement for the delegate to interact. Case studies are included to illustrate how problems can develop as technology changes.

A design project is included to enable the delegate to practice the techniques of calculating the parameters of loads, protective devices and cable sizing for safety and functional purposes. A calculator will be required for this phase of the course.

Questions are welcomed throughout the course and during break sessions.

Organisational Impact

The additional knowledge will help in the design of new electrical installations
This knowledge will help in upgrading an existing installation when new technology is to be added
The course will help an organisation to improve its effectiveness in ensuring compliance with standards
Knowledge of the impact of new technology will help in ensuring reliability of an installation
Knowledge of the design implications to withstand failures due to power quality
How inspection, testing and maintenance improve the resilience of an installation

Personal Impact

On successful completion of this course, delegates will understand:

The basis for safety and functional design
How to assess the characteristics needed to commence a design process
The earthing and bonding requirements of an installation for safety and function
How new technology impacts on new and existing electrical installations
Inspection and testing techniques that affect the maintenance routine of an installation
How to improve productivity by improving power quality

Who Should Attend?

This course is aimed at personnel who would like to expand their knowledge of the safety and functional design of an electrical installation and is aimed at:

Mechanical and Electrical engineers
Mechanical and Electrical technicians
Electricians and Electrical Supervisors
Maintenance personnel with responsibility for an electrical installation

Programme Outline

Day 1 – Preliminary Design Requirements

The design process requires consideration of the installation requirements with respect to the load characteristics, the circuit arrangements, and the source of supply.

Building services
Purpose of an installation
Cables
External influences
Transformers
Compatibility
Protective devices
Maintainability

Day 2 – Design Characteristics

To enable work to begin on any electrical installation a detailed specification is required. This specification will be based on the safety and functional requirements considered in day 1.

Electrical safety
Cable installation
IEC 60364
Terminations
Wiring regulations
Inspection and testing
Cable sizing
Documentation

Day 3 – Designing an Installation

Building on the first two days of the course this module puts into practice the theories developed.

Single phase design
Power quality
Three phase design
Cable requirements
Protective device selection
Installation method
Earthing and bonding
Source of supply

Day 4 – Commissioning and Testing

The requirements for any maintenance routine begin during the design process and continue though installation into operation. In many countries there is also a legal requirement to maintain an installation in a safe condition.

The need to maintain
Test results
What is maintenance
Documentation
Introduction to commissioning
Harmonics
Inspection
Earth leakage

Day 5 – Periodic Maintenance

After the initial verification of the safety and function of the installation it is necessary to ensure that safety remains effective throughout the lifetime of the installation.

Maintenance Planning
Periodic inspection
Equipment reliability
Complex testing
Categories of system
Harmonic analysis
Safety critical
