Download or read book Residual Current Devices written by Stanislaw Czapp and published by Academic Press. This book was released on 2022-01-11 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual Current Devices: Selection, Operation, and Testing looks at the evolution in construction types of residual current devices and discusses the types and functional properties of contemporary systems. The principle of operation of elements is explained, along with the primary parameters of the devices and their selection and application, as well as the rules of backup protection of residual current devices. The requirements of the standards concerning the importance of obligatory use of devices are included, along with explanation of the needed protection in case of fault, additional protection, and protection against fire. The issue of residual current device operation in circuits with nonsinusoidal currents is detailed, giving special attention to the unique results of residual current device testing and tripping under distorted earth fault currents. In modern electrical and electronic installations, new complex challenges arise for designers and maintenance staff. This book is an essential guide to address those challenges, and its problem-solving section is useful for students, tutors, and academics, as well as engineers involved in the process of design, maintenance, and verification of safety in low-voltage electrical installations. - Explains the practical aspects of the selection and utilization of residual current devices - Provides guidance on the operation of residual current devices in modern circuits characterized by nonsinusoidal earth fault currents - Features remedies for challenges in unwanted tripping of residual current devices during the obligatory verification of low-voltage systems

Download or read book Electrical Safety and the Law written by John M Madden and published by Routledge. This book was released on 2017-01-20 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical Safety and the Law describes the hazards and risks from the use of electricity, explaining with the help of case studies and accident statistics the types of accidents that occur and how they can be prevented by the use of safe installations, equipment and working practices. It describes the British legislation on the safety of electrical systems and electrotechnical machinery control systems, much of which stems from European Directives and which will therefore be affected by the UK’s decision to leave the EU (Brexit), and the main standards and guidance that can be used to secure compliance with the law. There are detailed descriptions covering the risks and preventive measures associated with electrical installations, construction sites, work near underground cables and overhead power lines, electrical equipment and installations in explosive atmospheres, electrical testing and electrotechnical control systems. Duty holders’ responsibilities for designing, installing, and maintaining safe systems are explained, as well as their responsibilities for employing competent staff. The fifth edition has been substantially updated to take account of considerable changes to the law, standards and guidance; it has been expanded to include: a new chapter on the Corporate Manslaughter and Corporate Homicide Act; a new chapter describing landlords’ legal responsibilities for electrical safety in private rented properties and social housing; a new chapter on the Electricity Safety Quality and Continuity Regulations; new information on offences, penalties, sentencing guidelines, and relevant case law; a description of the main requirements of BS 7671:2008 and other principal standards, many of which have been amended in recent years; new cases studies to illustrate the hazards and risks; information on changes to GB’s health and safety system.
