These information are completed with some short-circuit calculation examples and general criteria for the choice of the low voltage protection and control devices.


Technical Application Papers - Vol. 3

Distribution systems and protection against indirect contact and earth fault
The scope of this publication is providing the reader with the necessary information about the main normative aspects regarding protection against earth fault and indirect contact, clarifying the relevant problems and illustrating the solution proposed by ABB SACE. Particular attention is paid to the protection devices and to the way they operate (from the residual current devices to the last generation electronic trip units) and how to obtain selective co-ordination is thoroughly described. 


Technical Application Papers - Vol. 4

ABB circuit-breakers inside LV switchboards
This is the forth volume of the series “Technical Application Papers” issued by ABB SACE. 
The scope of this publication is providing the reader with the basic information necessary to choose in the easiest and most correct way ABB SACE circuit-breakers for installation inside LV switchboards. 
This choice shall be carried out by taking into consideration the problems linked to heating, any possible advice to improve the circuit-breaker current carrying capacity inside switchboards and all the questions involved by short-circuits.
This technical paper is completed with some examples and illustrations intended to give support to the reader for the concepts expressed.


Technical Application Papers - Vol. 5

ABB circuit-breakers for direct current applications
This is the fifth volume of the series “Technical Application Papers” issued by ABB SACE. The scope of this publication is providing the reader with the basic information regarding direct current , including both the most important application and the techniques used nowadays for the production of direct current. Besides there are precise information by means of table providing a rapid choice of the protection/disconnection device and paying particular attention to the installation characteristics (fault typologies, installation voltage, earthing arrangement).


Technical Application Papers - Vol. 6

Arc-proof low voltage switchgear and controlgear assemblies

Low voltage switchgear and controlgear assemblies are the components of electric installations which are more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.
In the last years a lot of users have underlined the ques­tion of safety in electrical assemblies with reference to one of the most severe and destructive phenomenon: the electric arc. 
he sixth volume of the series “Technical Application Papers” issued by ABB SACE, after a survey of the Standards applicable to switchgear and controlgear assemblies and of the relevant classification, gives the reader all the necessary elements to understand the effects of the electric arc and what are the solutions which guarantee safety for the operator and the plant in the event of an arc inside the assembly. 


Technical Application Papers - Vol. 7

Three-phase asynchronous motors - Generalities and ABB proposals for the coordination of protective devices
This Technical Application Paper (the seventh of the series) gives a description of the main starting modalities of three-phase asynchronous motors with particular reference to the standard prescriptions (Std. IEC60947-4-1); the most common starting typologies are illustrated in detail and an overview is given about the availability and the main characteristics of the ABB products used for co-ordination (products and relevant tables). The document is completed with annexes which give an analysis of some subject matters linked to the use of asynchronous motors.


Technical Application Papers - Vol. 8

Power factor correction and harmonic filtering in electrical plants
The eighth volume of the Technical Application Papers deals with the problems of power factor correction and harmonic filtering in electrical plants. Starting from an analysis of the technical-economic advantages offered by power factor correction, the methods used to implement power factor correction in a plant are described, the effects of harmonics are analyzed and then the reader is guided to the correct choice of ABB devices for the switching and protection of capacitor banks and harmonic filtering. 
This document is completed with six annexes in which some of the technical aspects relevant to the use of capacitors and filters are treated in details. 


Technical Application Papers - Vol. 9

Bus communication with ABB circuit-breakers 
The ninth volume of the Technical Application Papers deals with the subject of bus communication with the aim of introducing the reader to the basic concepts of networks and communications protocols, dialogue between “intelligent” electronic devices and, in particular, with the purpose of describing the main functions and the characteristics of the electronic trip units which allow ABB circuit-breakers to communicate via bus. In detail, this document has the purpose to offer all the useful information for the correct choice and the correct use of the electronic trip units, of the accessories and the products necessary to integrate ABB circuit-breakers in the supervision systems of electrical and technological installations.


Technical Application Papers - Vol. 10

Photovoltaic Plants
The tenth volume of the Technical Application Papers deals with the present global energy and environmental context, the aim of reducing the emissions of greenhouse gases and polluting substances (also further to the Kyoto protocol), also by exploiting alternative and renewable energy sources which are put side by side to and reduce the use of fossil fuels, doomed to run out due to the great consumption of them in several countries, has become of primary importance.


Technical Application Papers - Vol. 11

Guidelines to the construction of a low-voltage assembly complying with the Standards IEC 61439 Part 1 and Part 2
The purpose of this Technical Paper is:
1) describing the main innovations and changes introduced by the new Standards IEC 61439 Part 1 and Part 2 about switchgear and controlgear assemblies, with reference to the structure of the Standards, the definitions and the contents (e.g. design verifications of the assemblies and relevant application conditions), paying particular attention to the performance verifications for temperature-rise limits, short-circuit withstand strength and dielectric properties;
2) giving a document which includes useful information for the realization and certification of LV assemblies in compliance with these Standards.

Technical Application Papers - Vol. 12

Generalities on naval systems and installations on board
The purpose of this document is giving some information to help to better understand the structure and the problems linked to a LV electrical installation on board. Starting from a classification of the main typologies of ships, attention shall be paid to the structure which characterises the giant cruise ships, giving some hints on electrical power generation on board, on electrical plans on propulsion systems.
