Nikola Tesla. The first radio link of all time.What James Clerk Maxwell discovered in 1864 and what was experimentally proven by Heinrich Hertz in 1888, remained unused for many years: the knowledge of the existence of radio waves. However, in 1893 Nikola Tesla amazed the scientific world with a demonstration: On one side of a stage—the sender side—stood an oil-filled 5 kVA supply transformer, connected to a series of capacitors made from Leidener bottles, a spark gap, a coil and a wire that led to the ceiling. A similar wire, Leidener bottles and a coil were located on the receiver side. Once the transformer was switched on, a clearly visible Corona developed around the Leidener bottles. However, what could not be seen was that an electromagnetic wave was being sent through space, which was completely new. Radio technology was born. |
Energy Data Management for the FutureThe German Energy Management Act (EnWG) and the German Gas Network Access Ordinance (GasNZV) are delivering a new legislative framework - and more clarity in the gas market. The structure and data model of BelVis GAS have stood the test of time in that BelVis has already been used to implement many of the guidelines issued by the Federal Network Agency. Existing users of BelVis are already finding energy data management easier, and potential users have the assurance that future market policies will also be integrated in BelVis, such as nominated shipping, network access management, reporting requirements or vendor switch. |
