POWER QUALITY MANAGEMENT

Iskra Power Quality Systems

MiSMART

WEB based application comprised from● Push Data Collector● Database● Client

Operating system independent software● MiSMART vs SCADA● Not real time (except alarms)● Data lossless operation● Scalable and user-friendly● SMS and e-mail alarm notification

Standard SQL database● It can be used without the software solutions

Introduction

MiSMART

MiSMART Configuration Tools● Device data configuration● Setting up the system grid structure● User management

MiSMART Data Monitor● Measurement monitoring● Alarm monitor● Basic statistical functions● EN50160 power quality support● Table and chart data reviewing● Exporting data into Excel● Filtering relevant data from the grid● Data comparison from different meter points● Virtual metering points

Key functionalities

MiSMART

● Analysis of power quality in the grid for later corrective measures● Cost savings due to faster response to outagesfor better maintenance● Energy savings after corrective measures have been implemented● Historical data for better planning● Proactive equipment protection● More reliable grid operation● Better control of power theft and power losses in the network – this will especially be obvious when more sites are equipped with PQ analysers
