The Rogowski coil is a traditional current-to-voltage transducer. To use it for high-accuracy measurement of low frequency AC current, it is necessary to have a very precise sensor geometry and very specific conditions, such as a stable temperature and a centered primary conductor in order to minimize errors. Conversely, it is also possible to compensate(More)
While differences in greenhouse gas (GHG) fluxes between ecosystems can be explained to a certain degree, variability of the same at the plot scale is still challenging. We investigated the spatial variability in soil-atmosphere fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) to find out what drives spatial variability on the plot(More)
Rogowski coils (RC) used for high-accuracy contactless current measurement ask for precise sensor geometry and specific conditions, such as a centered primary conductor. To relax these constraints, we propose here a recently patented continuous calibration system which features a reference conductor added coaxially to the primary conductor and a(More)
