This substantially revised, third edition of Wright and Newbery's classic guide to the world of electric fuses remains the most comprehensive reference work on the subject. New topics covered include further analysis of prearcing and arcing behaviour; retrofitting of expulsion fuses with automatic sectionalising links; developments in chip fuses and automotive fuses; application information on benefits of fuses; IGBT protection; ach flash and power quality. There are also updated national and international standards, and glossary of terms. The broad treatment of fuses means that the book is intended not solely for those engaged in fuse development, design and production, but also for those responsible for planning and protection of electrical circuits and networks including electrical engineers along with specifiers, purchasing officers and technicians.
