Qiliang Richard Xu (Mí12) received the B.S degrees (Summa Cum Laude) in Mechanical Engineering from both University of Michigan, Ann Arbor and Shanghai Jiaotong University in 2008 and an M.S. degree in Mechanical Engineering from University of California, Berkeley in 2010. He is currently a Ph.D. candidate in the Mechanical Engineering Department at the University of California, Berkeley. His research interests include ubiquitous wireless sensing for intelligent infrastructures and energy harvesting from ambient near-field electromagnetic fields.
Deployment of Wireless Stick-On Circuit Breaker PEM AC Sensors for the Smart Grid [BPN505]
The electric power consumption of the entire Berkeley campus ranges from 18 to 30 MW, of which the Electrical Engineering building (Cory Hall) load comprises from 3% to 5%. Presently, the power entering the building is metered monthly at the primary terminals of its 12.4 kilovolt distribution step-down transformer. In order to increase energy efficiency and to experiment with, and further develop, our miniature electrical sensors, we are in the process of installing proximity sub-metering of loads accessed through a standard circuit breaker panel to which miniature proximity-based current sensors have been attached. We have also made a two-minute video, available from the BSAC web site, demonstrating the sensors in action.
