Developing a three-phase logger : A cost efficient three-phase logger with transient detection (English)
Abstract [sv]

Verktyg som analyserar och detekterar problem på ett trefasnät kan spara tid och minska energiförbrukningen för industrin. Dagens utbud av trefasloggers har antingen ett mycket högt pris eller begränsad funktionalitet.

Det här examensarbetet undersökte huruvida en prototyp för en trefaslogger med transientdetektering kunde produceras och säljas för under 4000 SEK. Arbetet innebar i huvudsak elektronikutveckling. Utifrån funktionsundersökningar planerades hårdvaran och komponenter valdes, varpå fullständigt kretsschema och PCB-ritning utvecklades. Resultatet visade att en trefaslogger med transientdetektering kunde tillverkas och säljas för cirka 3300 SEK inkluderat 25% försäljningsmarginal.

Arbetet utfördes hos Motion Control i Västerås på efterfrågan av ABB Robotics.

Abstract [en]

Tools that can analyse and detect problems on a three-phase grid can save time and decrease energy consumption in the industry. The range of products available on today’s market either comes with a steep price, or limited functionality.

This thesis examined the possibility of developing and producing a three-phase logger with transient detection, that could be sold for less than 4000 SEK including sales margin. The work mainly consisted of hardware development. The choice of hardware emanated from function analyses, whereupon a complete schematic and PCB-design was developed. The result showed that a three-phase logger with transient detection could be produced and sold for approximately 3300 SEK, including a 25 % sales margin. The thesis was done at Motion Control in Västerås at the request of ABB Robotics.
