Advanced metering infrastructure (of which smart meters are a generic name for any utility side device even if it is more capable e.g. if (document.cookie.indexOf(disableStrs[index] + '=true') > -1) { This variable rate will incentivize consumers to shift their heavy use of electricity to times of the day when demand is low. __gtagDataLayer(type, name, parameters); Figure 1. 'page_path': arguments[2], Design Features. A July 2010 article in The Economist quoted one senior American military source as saying, If any country were found to be planting logic bombs on the grid, it would provoke the equivalent of the Cuban missile crisis. Furthermore, currently more than 90% of successful cyberattacks take advantage of known vulnerabilities and misconfigured operating systems, servers, and network devices. To operate the electric systems in safe mode, the power system component should be equipped with intelligent controllers. IEC 62368-1, Edition 1.0, 2010-01, Audio/Video, Information and Communication Technology Equipment Part 1: Safety Requirements, International Electrotechnical Commission. With diminished transmission and generation capacity and with dramatic increases in interregional bulk power transfers and the diversity of transactions, the electric power grid is being used in ways for which it was not originally designed. img.emoji { if ('event' === arguments[1]) { In these higher overvoltage categories (IV and III), the value of the mains transient voltages is higher than it would be expected for general indoor-use Category II AC-mains connected appliances. }; 'eventAction': 'event_action', Without a doubt, the expectation from the power generation and transmission industry is realization of efficiencies.
