Power Supply Devices and Systems of Relay Protection brings relay
protection and electrical power engineers a single, concentrated
source of information on auxiliary power supply systems and
devices. The book also tackles specific problems and solutions of
relay protection power supply systems and devices, which are often
not dealt with in the literature. The author, an experienced
engineer with more than 100 patents, draws on his own experience to
offer practical, tested advice to readers. A Guide to Relay
Protection Power Supply for Engineers and Technicians The first
chapter reviews the electronics and primary elements of the system,
including transistors, thyristors, optocouplers, logic elements,
and relays, and their principles of operation. This background
gives staff who service relay protection power supply systems the
necessary electronics knowledge to help them work more effectively
with the equipment. The next chapters of the book then cover
built-in digital protection relay power supplies, battery chargers,
accumulator batteries, uninterruptible power supply, and
characteristic features of auxiliary DC systems at substations and
power plants. The final chapters discuss questions and problems
that engineers and technicians may face. These include insulation
problems, issues in auxiliary DC power supply such as voltage dips,
and electromagnetic disturbances such as blackouts, spikes, and
surges. The author also explains how to address them. Suitable for
beginners and experienced engineers alike, the book is written for
those who work with relay protection systems and with AC and DC
auxiliary power systems in power plants and substations. It
combines theory and practical recommendations to provide a valuable
reference on power supply devices and systems.
