Introduction

MiDGIS™ – is a GIS based Distribution Analysis and Planning package. It is a user friendly windows based application that can be used by companies engaged in the business of power distribution. MiDGIS™ is available as a Desktop – Client Server model. Core engines like load flow, short circuit analysis are very robust, field proven and time tested for decades. Modelling the systems and performing various analysis is simplified. Once required data is collected, it can be modelled and analysed within minutes.

MiDGIS™ brings network analysis and geo spatial / location information together. With location information utility is empowered with visuals, utility will be well equipped to supply quality power, safety and improved reliability with good protection system and contingency management, well managed outages, compliance, reduction of loss, cut costs and more.
