Development of three phase transformer lab : A study about transformers (English)
Abstract [sv]

Examensarbetet har utforts pa uppdrag av enheten for Data- och

Elektroteknik pa skolan for Teknik och Halsa, KTH.

Denna studie om transformatorer omfattar deras funktioner och

anvandningsomraden, hur de ar uppbyggda, hur karnan och lindningarna

som ar transformatorns viktigaste delar ar uppbyggda, vilka materiel som

anvands vid konstruktion av dessa samt vilka typer det finns av dem

beskrivs i rapporten. Vidare beskrivs flera olika transformatortypers

funktioner och anvandningsomraden. Eftersom en viktig del av studien

varit pa vilka satt transformatorer kan utvecklas for okad miljovanlighet

och livslangd gar rapporten igenom olika vegetabiliska oljor, vilka

fordelar de har gentemot mineraloljor och vilka egenskaper de har samt

pa vilket satt de ar skonsammare mot miljon. HVDC-enheter

transformerar hoga spanningar fran vaxelspanning till likspanning for

mindre resistiva forluster och darmed lagre energiforluster vilket i sin tur

leder till en renare miljo.

Teorigenomgangen av transformatorn ligger till grund for utformningen

av en laboration for undervisningsbruk, bl.a. i en kurs om elkraftteknik

som ges i hogskoleingenjorsprogrammet Elektroteknik pa KTH.

Abstract [en]

This degree project was carried out on behalf of the unit for Computer

and Electrical engineering at the School of Technology and Health, KTH.

This study about transformers, their function and uses, the way they’re

built, how the core and windings, which are the most important parts of a

transformer, are made and what kind of materials are used to make them.

Several types of transformers and their functions are described. A crucial

part of the study has been to search for different ways to develop

transformers to make them environmentally safer and to increase their

life-span. As such this work describes different transformer oils, what

advantages and disadvantages they have compared to mineral oils, what

properties they have and in what way they’re less harmful for the

environment. HVDC units transform high voltages from Alternating

Current to Direct Current to lessen the resistive losses and energy losses

which lead to a cleaner environment.

The theory examination of the transformer is the basis for the formation

of a lab for educational use, among others in a course about electrical

power that’s included in Bachelor of Science in Electrical Engineering at

KTH.
