Measurements in industrial network laboratory

The quality of supply and EMC are important in industrial networks. A small industrial power network for studying disturbances is being built in the laboratory at Tampere University of Technology. Besides research, the laboratory can be used for teaching. The aim of this paper is to describe the measurements used in the laboratory for investigating disturbances. The laboratory consists of different types of motors and other components that can be found in the industrial power networks. The currents are measured from each feeder of the network. Voltage is measured from bus bars. The measured signals from the small network can be fed into a computer with an 8-channel measurement card. The measured signals are analyzed with different programs. Some examples of measurements are presented in this paper. The laboratory is being developed and will still be expanded. This will ensure the usability of the laboratory in the future
