Analysis of Power Supply Parameters for Indirect Process Control

Most processes in chemical technologies are performed on non-transparent equipment (metal, opaque plastic, thermally insulated equipment). This prevents visual monitoring of the process in progress and, in certain cases, necessitates the installation of costly and sophisticated optical sensors in the machinery in order to enable the automation governing the process to make the required decisions. At the same time, most of these changes can be detected by indirect signs using sensors already installed in the system, which makes it possible to simplify and reduce the cost of parameter monitoring methods. One of these methods can be the use of data received from a monitor of electrical network parameters. In some cases, changes in the value of consumed currents, active and apparent power can be clearly associated with the processes occurring in the “black box”, and after proper calibration, serve as reliable criteria for making certain decisions.
