Power quality in high-tech campus: An exemplary case study

This paper presents preliminary results from a power quality audit conducted at a high-tech campus over last year. Voltage and current were measured at various R&D buildings. The paper examines the causes and effects of power disturbances that affect computer or any other microprocessor based equipment and analyses the auto-protection capabilities of modern power supplies. The convenience of “enhanced power supply” or “low-cost customer-side” protection solutions is also discussed. Finally it is addressed the role of the Standards on the protection of electronic equipment and the implications for the final costumer.
