Application of a power quality analyser to the monitoring of sand preparation processes in foundry plants

Process control plays a major role in supervision and identification of states, for example in monitoring of electric circuits power - supplying the foundry machines and devices, such as sand preparation processes, moulding technologies, melting, cleaning and finishing of castings. The monitoring and control equipment includes the power quality analysers. Testing is done using a Japanese analyser KEW 6319 (Kyoritsu) applied to monitoring of the sand preparation process in a foundry plant with low level of mechanization, equipped with the sand preparation unit based on a roller mixer.
