The scope of this electrical installation handbook is to provide the designer and user of electrical plants with a quick reference, immediate-use working tool. This is not intended to be a theoretical document, nor a technical catalogue, but, in addition to the latter, aims to be of help in the correct definition of equipment, in numerous practical installation situations.
The dimensioning of an electrical plant requires knowledge of different factors
relating to, for example, installation utilities, the electrical conductors and other
components; this knowledge leads the design engineer to consult numerous
documents and technical catalogues. This electrical installation handbook,
however, aims to supply, in a single document, tables for the quick definition of
the main parameters of the components of an electrical plant and for the selection
of the protection devices for a wide range of installations. Some application
examples are included to aid comprehension of the selection tables.
Electrical installation handbook users
The electrical installation handbook is a tool which is suitable for all those who are
interested in electrical plants: useful for installers and maintenance technicians
through brief yet important electrotechnical references, and for sales engineers
through quick reference selection tables.
Validity of the electrical installation handbook
Some tables show approximate values due to the generalization of the selection
process, for example those regarding the constructional characteristics of
electrical machinery. In every case, where possible, correction factors are given
for actual conditions which may differ from the assumed ones. The tables are
always drawn up conservatively, in favour of safety; for more accurate calculations,
the use of DOCWin software is recommended for the dimensioning of
electrical installations.
Summary of ABB's Electrical Installation Handbook
Electrical Installation Handbook 5th edition (two volumes+software "Curves 1.0")
It is an indispensable tool for all those who are interested in electrical plants.
Volume 1: Protection and control devices
This volume deals with the following subjects:
- general characteristics of the circuit breakers;
- derating tables for circuit-breakers (temperature and altitude);
- co-ordination tables;
- special applications (direct current, 400 Hz and 16 2/3 Hz, 1000 Vdc and 1000 Vac);
- electrical switchboards;
- examples with advanced protection functions.
Volume 2: Electrical Devices
This volume deals with the following subjects:
- protection and dimensioning of feeders;
- protection and switching of lighting circuits, generators, motors and transformers;
- power factor correction - protection and switching of capacitors bank;
- protection of human beings against direct and indirect contacts - distribution systems;
- calculation of short-circuit current;
- harmonics.
Software: "Curves 1.0" (available exclusively together with the printed version)
It is an tool dedicated to who works in the electrical engineering field.
This program can display:
- trip curves;
- specific let-through energy curves;
- limitation curves;
- cable and fuse characteristic curves;
- the discrimination and back-up values which can be obtained by the different combinations of ABB circuit-breakers.
Besides, thanks to the software "Curves 1.0", it is possible to export the curves and settings of the circuit-breakers to any text editor or drawing program.
