By order of a power plant, VISCOM Visual Communications created a data analysis and visualisation system for the largest high-voltage switching station in the south-east of Switzerland. It records more than 20,000 analogue and digital data points starting at the power plant control system, and enables comfortable evaluation and displaying on the screen. Thus, the system essentially contributes to the problem-free operation of the power plant, and helps the operating personnel to take the correct measures in each case.
