Smart electric energy measurements in power distribution grids
IEEE Instrumentation & Measurement Magazine, 2015Smart Grid (SG) is an expression that has diffused worldwide. However, the meaning of this expression is not commonly shared, since there is not yet a totally defined or accepted idea of smartness. What is commonly recognized is that significant changes are occurring in electric systems, and traditional management and protection schemes will not be ...

Solid surface energy measured electrically
Journal of Physics D: Applied Physics, 1990A new method is described for determining the surface energy of conducting powders. The technique depends on the relation between surface energy and contact diameter of two smooth elastic spheres touching under zero external load. Since electrical conductivity through the contact is also a function of contact diameter, an equation relating conductivity

About the Validity of Measurements in an Electric Power System with Electric Energy Storages
Elektrichestvo, 2020The validity and completeness of data in an electric power system are achieved by state estimation, which is aimed at filtering measurement errors and calculating unmeasured operating parameters. Highquality estimates can be obtained if there are no gross errors in measurements, which are revealedand eliminated at the stage of detecting erroneous data,

A New Electronic Method for Electric Energy Measurement
IEEE Transactions on Instrumentation and Measurement, 1975A new electronic method for electric energy measurement is described. The suggested method makes possible the construction of watthour meters without directly employing an electronic multiplier. The method is based on the utilization of a V/F converter with an inverse F/V conversion in the feedback loop.

Measurement of the Energy Released in Nanosecond Electric Sparks
Combustion Science and Technology, 1972Abstract Ignition energy can be determined by means of electric sparks produced by a transmission-line method. The energy released in the spark discharge is calculated from recordings of the voltage pulses incident onto and reflected by the spark gap.
