From eight words a minute to 13 terabits per second in 150 years

IEC first President Lord Kelvin was central to the success of the first fully working transatlantic telegraph cable

Given today’s low-cost or free crystal-clear voice calls and the real-time transfer between continents of vast volumes of data, including multimedia content, it’s easy to forget that just 150 years ago it took nearly two weeks for news from London to reach New York. The laying of the first fully working transatlantic telegraph cable from Ireland to Newfoundland cut that time to a few hours. IEC first President Lord Kelvin played a key role in the success of the project.

Standards support Smart Grid architecture

IEC International Standards will play critical role in Smart Grid power supply and distribution infrastructures

Information is gathered and decision making occurs at substation level in Smart Grids. The electricity-dispatching control centre deals with the strategic management of grid intelligence, while automated management handles transmission and distribution. An intelligent substation reports electricity consumption, switchboard operation, information gathering, and station decision making back to the electricity dispatching control centre. Generally, substations are unattended and rely on supervisory control and data acquisition (SCADA) for remote supervision and control.
