Abstract [en]

This degree project is performed at Rosti-Primpac AB located in Norrköping and comprises measurements with an analysis of the companys powersystem.

The project is divided in a theory part, an overview of the power system, a description of the machines, a compilation of the results from our measurements and finally conclusions with a list of actions that might be performed.

Rosti-Primpac AB have had some problems with their Blowmolde-machines Sidel 4 and Sidel 5 who kept failing without any known reason, which have caused breaks in their production. The company management suspected that this might came as a result of harmonics in the electrical system. Our task was to investigate this. We decided to perform an investigation on all their

Blowmold-machines. Other components in the electrical system were also included in the measurements, in order to create a complete image of the electrical quality. The main focus was laid on measuring harmonics, according to wishes from the company.

The main purpose of this project were fulfilled in that we, with help of our measurements, could come to the conclusion that Rosti-Primpac AB have an overall good power quality and that the machine-stops probably do not depend on electrical problems.
