An analysis of the influence of microclimate on partial discharge activity in emissions of electric machines in the conditions of industrial operation – own research

Abstract

The article presents the results of diagnostic measurements of partial discharge signal propagation from the winding insulation in electrical machinery, which were performed using an on-line method. This paper describes the results of experiments and the acquired experience in the monitoring of winding insulation in high power and high voltage electrical machines which are important in industrial production processes. The authors show the measurement techniques employed in their research. Representative measurement results are presented along with their analysis. The authors use an SKF monitoring systems to measure: vibrations, temperature, and humidity, as major factors affecting partial discharge activity in the from winding insulation of electrical machines.

“…Nowadays, in the industry, as-built and post-assembly measurements with the use of laser techniques are increasingly used. An example can be e.g., a 3D scanner, the operation of which is described in [15]. This technique makes it possible to more accurately determine the coaxiality of the shafts connected by a clutch, taking into account not only the accuracy of the shaft surfaces, but also considering them as a comprehensive system.…”
