<p>The invention relates to Current and/or voltage sensing device (1) with primary (2) and secondary circuits (3), for medium and/or high voltage AC - power grids, with design features, in order to cause a minimum phase error phase error and/or phase displacement and/or phase shift in the current and/or voltage sensing device, according to the preamble of claim 1. In order to realize a phase error compensation for current and/or voltage sensing device, which is much easier to design with lower constructional expense, the phase displacement/error/shift is improved or minimized by impedance matching element (6), which is connected to and/or within the secondary circuit of the current and/or voltage sensing device.</p> |
