Complex analysis of the voltage and current of the switchgear input for monitoring of the powered device condition

3. 11. 2020

TES s.r.o. in cooperation with the Brno University of Technology, the Department of Theoretical and Experimental Electrical Engineering, have been working on the project aiming to enable  remote evaluation of  the connected electrical devices, for example electrical motors,  by measuring of the  current and voltage waveforms at the power input  of the switchgear.

The use of the methods for measurement, signal processing, spectral analysis by the fast Fourier transformation and the MCSA analysis (Motor Current Signature Analysis) are used to fulfil above mentioned goals. Project outputs include methods and procedures for regular analysis of measured quantities and the innovation of the software for data analysis. The connected devices, such as large asynchronous motors, requires complex non-destructive diagnostic method of the technical condition which can be performed during operation without need of any interruption.

The ability of data monitoring at the switchgear offers a potential for a significant increase of frequency of data measurement which improves the chances for early detection of the change or early stage malfunctions of the connected device. The innovation of the software tools for data processing of a wide range of connected devices is a key instrument for quick and effective detection of changes in measured quantities.
