MEASURING METHOD AND SYSTEM FOR SIMULTANEOUSLY DETERMINING THE ELECTRIC QUANTITIES IN TRANSFORMER STATIONS, SUBSTATIONS AND POINTS

摘要

The invention relates to a measuring method and a system for determining and simultaneously recording the variation in time of the interdependent electrical quantities from transformer stations, substations and points for the supply with electrical energy The method claimed by the invention consists in taking over the determinations and digital records from some individual data acquisition systems followed by the synchronization of these determinations and records by means of a software program package, then the records are transferred to a graphical station or a personal computer which displays the variation in time of the recorded electrical quantities by using a dedicated software program. The measuring system claimed by the invention consists of some identical subsystems (6) for data acquisition, each having "m" input channels, each subsystem (6) being connected to a station (7) or substation for supplying with electric energy, by means of some conditioning blocks (8), the operation thereof being synchronized by a synchronization block (9) and the information determined and recorded being displayed on some displays (10) of a graphical station or of a computer.
