▼Chapter 5SoftwareTopology View (Graphical User Interface)A device view of any instrument in the network can be called up.Beside watching the actual display, you may also remotely control thecomplete instrument same as if you were on site. All measured datacan be displayed simultaneously. The topology gives a quick overviewof the energy distributions and the possibility to locate power failuresby comparing measuring points and checking the defined tolerances ata glance.Depositing some graphical files (common formats such as .jpg) withcircuit diagrams, flow processes or building plans and binding of thecorresponding instruments by drag and drop to their real position, youcan establish customer specific solutions quickly and simply. Limitviolations e.g. high THD-V as well as conditions of inputs or outputscan be indicated as well.Event and transient browser▼With the two functions EVENT- and TRANSIENT-browser, freelydefinable time periods can be checked regarding occurred events andtransients. These functions (e.g. illustration: transient browser) areespecially essential for failure analysis.Illustration: Transient browserOffline dataIllustration: Freely configurable data saving and average timesData memoryMost measuring instruments have a memory. Reading out thememory, the data are saved within a database. e.g. Derby, SQL andMySQL are available. The most preferable databases are MySQL orMicrosoft SQL server databases, as they are much faster then the derbydatabase, which is of importance especially in large projects. MySQLcan be downloaded free of charge at www.MySQL.org.Data stored in the GridVis database can be displayed as line graphs,bar graphs or histogram. Also parameters such as year month andday are stored. Therefore, the data can be easily selected.Particularly interesting periods of time can be enlarged with thezoom feature. The graphs can be provided with titles and commentsand be printed out. The display of transients and events alsotakes place here within the transient and event browser. The flagbrowser can be used to examine whether measurement data aremissing at certain periods of time or whether the data are not reli -able. With the anaysis of historical data you can build load profiles,for exact demand analysis for optimised supply contracts. Alsofailure analysis by comparing various parameters can be carriedout by a few mouse clicks.151
