【 摘 要 】
The following case study examines a company which experienced several difficulties caused by low-quality voltage supply. Two main points were considered in the analysis, one located next to the substation transformer and a second one inside the company. Voltage parameters such as harmonics presence, voltage flickers, average voltage, and power factor were measured in this study. As a result, 62 000 samples were collected. The data obtained from point 2 (control group) revealed the necessity of introducing voltage regulators in order to improve the energy efficiency and save in energy costs at the company. Therefore, 1 500 samples were collected at point 2 (treatment group) to verify the voltage regulators' efficiency. Comparing the control and treatment group, there was a significant improvement of 93% regarding process capability in power factor phase CN.
