Combined protection and control equipment for applications in the medium-voltage area

The paper illustrates the electrical stations of medium voltage in which there is going to be implemented an automated multivariable system, based of software packages for data acquisition, storing, data transmission, processing, monitoring, analysis and which to allow the monitoring of a large number of parameters. The purpose of the local data acquisition, protection and control equipment and of the monitoring system is to befriend the human factor in taking optimal decisions in the plan of monitoring the quality of electrical energy in distribution stations, by offering adequate information in a format specific to the function and work place.
