Within the paper the procedures - for carrying out detailed experimental investigations by the aid of digital Measurement Data Acquisition systems, for evaluating the measuring results as well as for aggregating the load type specific power consumption - are pointed out in general form. The results received concerning the load type specific power consumption are presented and discussed in detail at the example of the 15 MW power distribution system of the University of Stuttgart.
Based on these experimental investigations countermeasures had commercially been installed. As a result of this, 20 percentage of the consumed electrical energy could be saved especially by applying thyristor based speed control to asynchronous motors.
