Code of Practice for Electrical Safety Management, 2nd Edition (e-book)

Thu, 19 Jan 2023 11:38:41 GMT

The aim of this Code of Practice is to provide good practice guidance to enable individuals and their organisations to have a level of knowledge and understanding to manage the risks associated with an electrical system. There are many technical publications that provide guidance on certain aspects of electrical safety but not in a way that provides a process for managing electrical safety.

In achieving this aim, the Code of Practice has the following objectives:

To provide the good practice practical guidance in the form of a self-assessment framework so that the user can follow a systematic approach to understanding the management of various aspects of an electrical system for their organisation.
For the guidance to be understood and usable by a broad range of individuals technical and non-technical disciplines in any country.
To enable the end user to create and implement an effective electrical safety management system where nothing is currently in place or to enhance an existing system.

It has been updated to include considerations around the management of change, the implications of outsourcing work on the electrical equipment and installations, and an updated self-assessment tool to identify what systems exist and how effective they are in managing responsibilities.

Guidance Framework for Competence Management (e-book)

Wed, 14 Dec 2022 09:11:00 GMT

Competence involves much more than technical training; it includes a person's attitude and behaviour, as well as their experience and knowledge, and it's hugely important to all engineering organisations and those involved in engineering projects. Employing the right people, safety considerations, winning tenders, having effective succession plans, and identifying training needs and promotion opportunities are all drivers for having a strong competence scheme in place.

This guide provides a framework for a Competence Management System (CMS) that's simple and has a focus on practicable implementation. The guidance is aimed at all enterprises involving activities associated with engineering disciplines such as design, installation, operation, maintenance, manufacture, inspection, testing and training. The framework has been designed to allow adaptation to meet the specific requirements of individual organisations or projects.

Guide to Electrical Maintenance, 2nd Edition (e-book)

Wed, 06 Jul 2022 07:56:56 GMT

Good maintenance regimes do not happen by accident: they need careful planning, proactive management and comprehensive reporting.

This Guide has been prepared for all those involved in maintenance; electrical technicians, maintenance managers and also office-based design staff. The document provides updates to the original text where necessary and introduces additional items and areas for consideration as part of a maintenance programme. Appendix B in the original document now forms a new Section to provide greater focus on the practical aspects across a wide range of electrical installations. Additional topics have been added, and the format revised to make it a more practical tool for technicians and supervisors alike.

A good maintenance regime has an increasingly significant role in a more sustainable world where correctly maintained electrical systems keep operating at their maximum energy efficiency for longer and are disposed of correctly at the end of their lifecycle.

Guide to Earthing and Bonding for AC Electrified Railways (e-book)

Wed, 22 Jun 2022 13:11:35 GMT

The complexity of integrating the earthing of an AC electrified railway with various electrical distribution systems and exposed conductive parts means that it is impossible to prescribe one earthing and bonding design solution that addresses the needs of every railway. Therefore, different earthing designs are needed for individual railways.

This new Guide describes the underlying principles and typical configurations for the earthing and bonding of electrical traction system assets and other lineside assets and structures to reduce hazards to people and failures to equipment and systems. It also aims to assist infrastructure owners, railway designers and installation contractors in adopting a harmonised approach towards earthing and bonding design philosophy for AC railway infrastructure.

The work has been split into 10 sections covering:

AC traction electrification distribution system
Mass of earth as part of the traction return system
Traction return requirements and circuit configuration
Protection against electric shock
Electrification system assets excluding the traction return
Assets not forming part of the traction return
System measurements
Lightning protection for railway structures
Earthing and bonding at AC/DC interfaces
Safe working during maintenance, renewal and decommissioning.

This new Guide explains the principles of a 'common earth' system (traction and non-traction) which is able to provide a robust and low impedance path to Earth.

Code of Practice for the Application of LED Lighting Systems

Tue, 15 Feb 2022 17:44:58 GMT

This e-book is available through the IET’s digital Wiring Regulations platform. Once you have completed your purchase, details of how to download and access your e-book will be sent to you with your order confirmation.

LED lighting is a fast-developing technology with many advantages over filament and gas discharge lighting systems. However, inappropriate design, application and poor-quality installation of LED lighting systems could negate these advantages and result in inadequate lighting, failure to meet lifetime performance expectations, potential public health and safety issues or even interference with other technology due to poor systems integration.

This 2nd edition has been updated to reflect new standards and guidance including: asset management, application and testing, performance, power management, dimming and flicker, communication protocols (DALI2) and wireless networking and controls, with additional considerations including health and biologically effective lighting. The Code is necessary for all those responsible for design, installation, integration and management of lighting systems.
