Electrical interference handbook

Monograph, the 2nd edition, Newnes, Oxford (GB), 1998, pg. 271 Electrically operated items are commonplace today, be they in the house, industry or around us. Their sophistication has made life easier, but their very proliferation has led to a greater need to guard against mutual interference. This book is aimed at those concerned with protection and who are technically educated, but need a better awareness of the causes and effects of electromagnetic compatibility (EMC). Just as a well-cooked food can be ruined in the presentation, so well-designed equipment can have its EMC protection ruined by illconsidered installation. The measures needed to avoid spectrum pollution and protect from the electromagnetic environment are outlined in a hopefully readable and understandable fashion. Additional material which does not need to be read for general understanding of the subject has been included and is identified by a different print font. Technological advances in the various sciences have taken many tasks out of our daily existence, but some have added new problems. Some of these problems are life threatening, others merely a nuisance - electromagnetic interference can fall into both categories. Authenticated cases of the effects of interference, some aspects of which have been studied by the author, have included: • military fly-by-wire aircraft crashing after flying low over a high power radar transmitter; • a private car crashing into a bus stop and killing people when a passing taxi radio interfered with the ABS braking system; • mobile telephones interfering with hospital life-support equipment; • car remote locking systems being incapacitated when close to police station transmitters in the UK; • a computer screen turning blue and corrupting text due to the magnetic fields from an underground electric train; • the electric fields from the arcing of the power pick-up on electric trains interfering with the track-borne signalling; • early electric petrol pumps being made to deliver free petrol when subjected to the nearby fields from a car-mounted high power radio; • television screens being interfered with by an electric hair dryer. CONTENTS: Introduction Directives, regulations and standards National authorities and standards The EMC environment Radio wave propagation Susceptibility /immunity Emission and susceptibility protection Conducted interference Installation Testing Management Domestic and white goods community aspects Information technology aspects Architectural interests Transport community interests Medical equipment aspects Electrical security aspects Illumination aspects Appendix Index The Directive on EMC, and others affecting the electrical and electronics industry, are now firmly in place. In this updated guide the causes, effects and penalties of electrical interference are explained. Remedies such as methods of minimising emissions and maximising immunity are surveyed.

This handbook gives an insight into the various national and international standards and test methods. Case studies illustrate the challenge in various major industrial sectors including buildings, domestic appliances and white goods, IT, transport and automotive, lighting, medical equipment and security.
