Design and implementation of a remotely accesible inrush current testing package for power (distribution)transformers

Abstract

Inrush current or surge current in Power (distribution) transformers has been known to exist since transformers were first designed and manufactured. Since that time, the phenomenon has been researched, modelled and factored into designs. This project analyses the harmonics that exist within inrush current and also the techniques utilised in the managing of nuisance tripping caused by the high inrush current spikes. Additionally this project provides training and education tools for University Students. Primarily through a theoretical module and then complimented by a practical observation activity on a test rack suitable for remote access.
