Introduction

Scope and objectives

The scope o this electrical installation handbook is to provide the designer anduser o electrical plants with a quick reerence, immediate-use working tool. This

is not intended to be a theoretical document, nor a technical catalogue, but, inaddition to the latter, aims to be o help in the correct defnition o equipment,in numerous practical installation situations.

The dimensioning o an electrical plant requires knowledge o dierent actorsrelating to, or example, installation utilities, the electrical conductors and othercomponents; this knowledge leads the design engineer to consult numerousdocuments and technical catalogues. This electrical installation handbook, ho-wever, aims to supply, in a single document, tables or the quick defnition o themain parameters o the components o an electrical plant and or the selectiono the protection devices or a wide range o installations. Some application

examples are included to aid comprehension o the selection tables.

Electrical installation handbook users

The electrical installation handbook is a tool which is suitable or all those who areinterested in electrical plants: useul or installers and maintenance techniciansthrough brie yet important electrotechnical reerences, and or sales engineersthrough quick reerence selection tables.

Validity o the electrical installation handbook

Some tables show approximate values due to the generalization o the selec-

tion process, or example those regarding the constructional characteristics oelectrical machinery. In every case, where possible, correction actors are givenor actual conditions which may dier rom the assumed ones. The tables arealways drawn up conservatively, in avour o saety; or more accurate calcu-lations, the use o DOCWin sotware is recommended or the dimensioning oelectrical installations.

1.1 General aspects

In each technical feld, and in particular in the electrical sector, a conditionsufcient (even i not necessary) or the realization o plants according to the

status o the art and a requirement essential to properly meet the demandso customers and o the community, is the respect o all the relevant laws andtechnical standards.Thereore, a precise knowledge o the standards is the undamental premiseor a correct approach to the problems o the electrical plants which shall bedesigned in order to guarantee that acceptable saety level which is neverabsolute.

Juridical Standards

These are all the standards rom which derive rules o behavior or the juridical

persons who are under the sovereignty o that State.

Technical Standards

These standards are the whole o the prescriptions on the basis o whichmachines, apparatus, materials and the installations should be designed, ma-nuactured and tested so that efciency and unction saety are ensured.The technical standards, published by national and international bodies, arecircumstantially drawn up and can have legal orce when this is attributed bya legislative measure.

European Body CENELEC ETSI CEN

This technical collection takes into consideration only the bodies dealing with electrical and electronictechnologies.

IEC International Electrotechnical Commission

The International Electrotechnical Commission (IEC) was ofcially ounded in1906, with the aim o securing the international co-operation as regardsstandardization and certifcation in electrical and electronic technologies. Thisassociation is ormed by the International Committees o over 40 countries allover the world.The IEC publishes international standards, technical guides and reports whichare the bases or, in any case, a reerence o utmost importance or any nationaland European standardization activity.IEC Standards are generally issued in two languages: English and French.In 1991 the IEC has ratifed co-operation agreements with CENELEC (Europeanstandardization body), or a common planning o new standardization activitiesand or parallel voting on standard drats.

CENELEC European Committee or Electrotechnical Standardization

The European Committee or Electrotechnical Standardization (CENELEC) wasset up in 1973. Presently it comprises 31 countries (Austria, Belgium, Bulgaria,

Cyprus, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany,Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,Netherlands, Norway, Portugal, Poland, Romania, Slovakia, Slovenia, Spain,Sweden, Switzerland, United Kingdom) and cooperates with 12 afliates (Albania,Belarus, Georgia, Bosnia and Herzegovina, Tunisia, Former Yugoslav Republico Macedonia, Serbia, Libia, Montenegro, Turkey, Ukraine and Israel) which havefrst maintained the national documents side by side with the CENELEC onesand then replaced them with the Harmonized Documents (HD).There is a dierence between EN Standards and Harmonization Documents(HD): while the frst ones have to be accepted at any level and without additionsor modifcations in the dierent countries, the second ones can be amendedto meet particular national requirements.EN Standards are generally issued in three languages: English, French andGerman.From 1991 CENELEC cooperates with the IEC to accelerate the standardspreparation process o International Standards.CENELEC deals with specifc subjects, or which standardization is urgentlyrequired.When the study o a specifc subject has already been started by the IEC, theEuropean standardization body (CENELEC) can decide to accept or, when-ever necessary, to amend the works already approved by the Internationalstandardization body.

EC DIRECTIVES FOR ELECTRICAL EQUIPMENT

Among its institutional roles, the European Community has the task o promul-gating directives which must be adopted by the dierent member states andthen transposed into national law.Once adopted, these directives come into juridical orce and become a re-erence or manuacturers, installers, and dealers who must ulfll the dutiesprescribed by law.Directives are based on the ollowing principles:harmonizationislimitedtoessentialrequirements;

onlytheproductswhichcomplywiththeessentialrequirementsspeciedbythe directives can be marketed and put into service;

theharmonizedstandards,whosereferencenumbersarepublishedintheOfcial Journal o the European Communities and which are transposedinto the national standards, are considered in compliance with the essentialrequirements;

theapplicabilityoftheharmonizedstandardsorofothertechnicalspecications

is acultative and manuacturers are ree to choose other technical solutionswhich ensure compliance with the essential requirements;

amanufacturercanchooseamongthedifferentconformityevaluationproce-dure provided by the applicable directive.

The scope o each directive is to make manuacturers take all the necessarysteps and measures so that the product does not aect the saety and healtho persons, animals and property.

Naval type approval

The environmental conditions which characterize the use o circuit breakers oron-board installations can be dierent rom the service conditions in standardindustrial environments; as a matter o act, marine applications can requireinstallation under particular conditions, such as:- environments characterized by high temperature and humidity, including salt-mist atmosphere (damp-heat, salt-mist environment);- on board environments (engine room) where the apparatus operate in thepresence o vibrations characterized by considerable amplitude and duration.

In order to ensure the proper unction in such environments, the shipping re-gisters require that the apparatus has to be tested according to specifc typeapproval tests, the most signifcant o which are vibration, dynamic inclination,humidity and dry-heat tests.

CE conormity marking

The CE conormity marking shall indicate conormity to all the obligations im-posed on the manuacturer, as regards his products, by virtue o the EuropeanCommunity directives providing or the afxing o the CE marking.

1.3 Types o releases

1.3.1 THERMOMAGNETIC RELEASES AND MAGNETIC ONLY RELEASES

The thermomagnetic releases use a bimetal and an electromagnet to detectoverloads and short-circuits; they are suitable to protect both alternating and

direct current networks.

A circuit-breaker must control and protect, in case o aults or malunctioning,the connected elements o a plant. In order to perorm this unction, aterdetection o an anomalous condition, the release intervenes in a defnite time

by opening the interrupting part.The protection releases ftted with ABB SACE moulded-case and air circuit-breakers can control and protect any plant, rom the simplest ones to thosewith particular requirements, thanks to their wide setting possibilities o boththresholds and tripping times.Among the devices sensitive to overcurrents, the ollowing can be conside-red:

thermomagneticreleasesandmagneticonlyreleases;

microprocessor-basedreleases;

residualcurrentdevices.

The choice and adjusting o protection releases are based both on the requi-rements o the part o plant to be protected, as well as on the coordinationwith other devices; in general, discriminating actors or the selection are therequired threshold, time and curve characteristic.

1.3.2 ELECTRONIC RELEASES

These releases are connected with current transormers (three or our accordingto the number o conductors to be protected), which are positioned inside thecircuit-breaker and have the double unctions o supplying the power necessaryto the proper unctioning o the release (sel-supply) and o detecting the valueofthecurrentowinginsidetheliveconductors;thereforetheyarecompatible

with alternating current networks only.The signal coming rom the transormers and rom the Rogowsky coils isprocessed by the electronic component (microprocessor) which compares itwith the set thresholds. When the signal exceeds the thresholds, the trip o thecircuit-breaker is operated through an opening solenoid which directly acts onthe circuit-breaker operating mechanism.In case o auxiliary power supply in addition to sel-supply rom the currenttransormers, the voltage shall be 24 Vdc 20%.

Besides the standard protection unctions, releases provide:

- measuraments o currents (Ekip LSI/LSIG + Ekip COM, Ekip M LRIU + Ekip COM,PR222, PR232, PR331, PR121);

- measurament o currents,voltage,requency,power,energy,power actor(PR223,PR332,PR122) and moreover or PR333 and PR123, the measure-ment o harmonic distortions is available;

- serial comunication with remote control or a complete management othe plant (Ekip LSI/LSIG + Ekip COM, Ekip M LRIU + Ekip COM, PR222,PR223, PR232, PR331, PR332, PR333, PR121, PR122, PR123).

When the release detects a residual current dierent rom zero, it opens thecircuit-breaker through an opening solenoid.

As we can see in the picture the protection conductor or the equipotentialconductor have to be installed outside the eventual external toroid.

1.3.3 RESIDUAL CURRENT DEVICES

The residual current releases are associated with the circuit-breaker in order toobtain two main unctions in a single device:- protection against overloads and short-circuits;

- protection against indirect contacts (presence o voltage on exposed con-ductive parts due to loss o insulation).Besides, they can guarantee an additional protection against the risk o frederiving rom the evolution o small ault or leakage currents which are notdetected by the standard protections against overload.Residual current devices having a rated residual current not exceeding 30 mAare also used as a means or additional protection against direct contact incase o ailure o the relevant protective means.Their logic is based on the detection o the vectorial sum o the line currentsthrough an internal or external toroid.This sum is zero under service conditions or equal to the earth ault current (I

)

in case o earth ault.

The operating principle o the residual current release makes it suitable or thedistribution systems TT, IT (even i paying particular attention to the latter) andTN-S, but not in the systems TN-C. In act, in these systems, the neutral isused also as protective conductor and thereore the detection o the residualcurrent would not be possible i the neutral passes through the toroid, since thevectorial sum o the currents would always be equal to zero.



47/547



In presence o electrical apparatuses with electronic components (computers,photocopiers, ax etc.) the earth ault current might assume a non sinusoidalshape but a type o a pulsating unidirectional dc shape. In these cases it isnecessary to use a residual current release classifed as type A.In presence o rectiying circuits (i.e. single phase connection with capacitiveload causing smooth direct current, three pulse star connection or six pulsebridge connection, two pulse connection line-to-line) the earth ault currentmight assume a unidirectional dc shape. In this case it is necessary to use aresidual current release classifed as type B.

One o the main characteristics o a residual current release is its minimum ratedresidual current I

n. This represents the sensitivity o the release.

According to their sensitivity to the ault current, the residual current circuit-breakers are classifed as:

- type AC: a residual current device or which tripping is ensured in case oresidual sinusoidal alternating current, in the absence o a dc componentwhether suddenly applied or slowly rising;

- type A: a residual current device or which tripping is ensured or residualsinusoidal alternating currents in the presence o specifed residual pulsatingdirect currents, whether suddenly applied or slowly rising.

- type B residual current device or which tripping is ensured or residual sinu-soidal alternating currents in presence o specifed residual pulsanting directcurrents whether suddenly applied or slowy rising, or residual directs mayresult rom rectiying circuits.

Residual current relay with external transformer

ABB SACE circuit breaker can be combined also with the residual current relaysRCQ 020/A with separate toroid in order to ulfll the requirements when theinstallation conditions are particulary restrictive, such as with circuit breakersalready installed, limited space in the circuit breaker compartment etc.Thanks to the settings characteristics o the residual current and o the triptimes, the residual current relays with external transormer can be easily installedalso in the fnal stages o the plant; in particolar, by selecting the rated residual

current In=0.03A with instantaneous tripping, the circuit-breaker guaranteesprotection against indirect contact and represents an additional measure againstdirect contact also in the presence o particulary high earth resistance values.Such residual current relays are o the type with indirect action: the openingcommand given by the relay must cause the tripping o the circuit-breakerthrough a shunt opening release (to be provided by the user).
