Tamper-resistant Smartpower Meters Rely On Isolated Sensors

摘要

Most residences and commercial buildings inrnthe United States currently use an old-stylernelectromechanical utility power meter torntrack electricity use. The meters are reli-rnable and cheap but hopelessly inadequaternfor use by a power-distribution system thatrnrequires accurate, repeatable power metricsrnas well as wired or wireless communica-rntions-in other words, the coming Smart Grid electrical-power-distribution system.rnThe Smart Grid depends on smart meters with sophisticated communication capabilities to monitor energy usage and allow residential and business consumers alike to make informed choices about how much energy to use and when to consume it. The Smart Gridrnfaces difficulties, though. Although, at the federal level, Washington has passed legislature such as the 2007 energy bill and the 2009 stimulus plan, utilities actually deploy power on a state-by-state basis.
