Abstract [en]

The task of this master's thesis was to design a transformer test bench while focusing on safety and usability. There are several safety risks when working with high voltages, therefore the high demand for safety precautions.

A bench was worked upon, and attachments, such as module frames

and banana connectors were integrated into the bench. Further, a list of

components were modied and installed on the new bench. A new design,

using a magnetic non-contact safety interlock switch and an easy-to-apply circuitry, was proposed and implemented. In addition to the implementation,

a code in LabVIEW was written in order to handle the measured data

from the tests that can be performed on a transformer. Several tests were

performed on a single-phase transformer and a three-phase transformer in

order to verify the function of the transformer test bench, with respect to

the design. Complications emerged due to random additive noise. After some

work, the noise was suppressed and the results showed that the equipment

worked well with the new design.

Finally, a user's manual was written in order to guide the user through the

wire connections, tests and the developed software in LabVIEW.

Abstract [sv]

En transformatortestbänk avsedd för laborationer inom forskning och utbildning har utvecklats, där fokus har lagts på säkerhet och användbarhet, eftersom arbete med höga spänningar medför säkerhetsrisker.

En bänk modierades för att möjliggöra fastsättning av moduler samt

banankontakter. Vidare anskaades elektroniska komponenter, bearbetades

och installerades. En design med en magnetisk switch samt lättanvända

kretsar föreslogs. Dessutom skrevs en kod i LabVIEW med ett brett

användningsområde. Ett  flertal tester utfördes på en enfastransformator

och en trefastransformator med syfte att säkerställa att komponenter-

na fungerar väl ihop med den framtagna transformatortestbänken. En

del komplikationer uppstod på grund av slumpmässigt, additivt brus.

Detta gick dock att undertrycka. Det slutliga resultatet visade att kom-

ponenterna fungerade väl ihop med den framtagna transformatortestbänken.

Slutligen skrevs en användarmanual med syfte att instruera använda-

re av transformatortestbänken beträande kopplingarna, testerna samt

mjukvaran som är skriven i LabVIEW.
