Influence of equipment modernization to parameters of electricity - case study

This paper is concerned with the impact of modernization of the machinery on parameters of of electricity for example the aluminum industry company. Examined was due to changes in factory equipment for power energy parameters. Was shown the selected parameters for the state before and after the upgrade. Statistical analysis were carried out. It was shown that the upgrading its machinery has a positive impact on the power supply parameters. It has been shown that, despite a substantial increase in installed power has decreased power consumption due to power factor correction. In addition, showed an increase in uneven power consumption.
