Summary of Content

This module concentrates predominently on electrical installations of relevance to the building services industry. This includes health and safety considerations from both legal and technical viewpoints. Of particular relevance are the Health and Safety at Work Act, Electricity at Work Regulations and the IEE Wiring Regulations. Students will be instructed on the various technical design and selection procedures that will produce a fully compliant installation. Also included is an introduction to communication, fire alarm and security systems and use of CAD to represent these systems.

Syllabus

The taught syllabus will cover the following areas: Electrical Installations: Introduction to Principles and Safety Devices: Protection, short circuit, overlead, earth fault, isolation, devices and characteristics, principle of discrimination and co-ordination. Electrical Installations: Legal Requirements and Regulations: BS 7671, 1992 and Electricity at Work Regulations, 1989. Health and Safety at Work Act. Assessment of general characteristics. Requirements for: protection against electric shock, protective conductors and earthing, isolation and switching, overcurrent protection, selection of live conductors, inspection and testing. Medium And Low Voltage Installations: Switchgear, fusegear, MCB, MCCB and contactors. Co-ordination and discrimination. Hazard identification and risk reduction. Power factor correction. Internal distribution systems. Types of cable, conduit, trunking. Cable selection. Types of earthing. Fault currents and volt drop. Earth fault protection. RCDs. Star and delta connected, balanced and unbalanced loads. CAD for electrical services (design of distribution scheme). High Voltabe (to llkv) Systems: Switchgear, distribtuion schemes - radial and ring systems. Substation layout, load flow analysis. Short Circuit calculation. Electrical Machines: Transformer, DC Motor and induction motor. Structure, operating principle, operating characteristics, efficiency, Control. Electrical Systems: Introduction to communication networks, fire alarm and security systems.

Learning Outcomes

On completion of this module the student should be able to:- Apply design guidelines to the selection of cables and overcurrent protection within a distribution system.- Design electrical installations that are fully compliant with Electricity at work Regulations and the Health and Safety at work Act.- Understand and perform simple calculations associated with electrical safety requirements.- Identify the hazards associated with electricity and select the appropriate hazard reduction technique for a given situation.- Perform calculations associated with discrimination and power factor correction.- Specify a suitable layout for a HV distribution scheme and perform load flow and short-circuit calculations.- Analyse the peformance of electrical machines. Extract parameters of interest. Selection of motors for a specific application.-Introduction to communication, fire alarm and security systems within the building environment.

Teaching / Learning Strategy

Basically presented by lecture, but suitably supported by tutorial, laboratory and seminar sessions.

Indicative Reading

B D Jenkins, Electrical Installation Calculations, Blackwell Scientific Publications, 1992 Current edition of IEE Wiring Regulations (BS 7671) and Electricity at Work Regulations. E W R Memorandum of Guidance

Transferrable Skills

Students will learn how technical subjects relate to 'real' professional project work. The importance of safety and legal requirements on the final design and selection of components will become appreciated. Progressively throughout the programme the relationship between theory and practise will become one of the main foundations on which the programme is based.
