| 摘要 |
The invention relates to a parameterizable merging unit for sensor-based measurement of current and voltage in high voltage networks or electrical grids operating with other voltage levels, according to the preamble of claim 1 and 14. In order to t enhance the electronical unit and the method to operate the same, in such, to result in a higher vulnerability of such systems to ambient disturbancy in an easy and constructively compact way, and to improve the measurement accuracy with that, the invention is, the aforesaid unit contains memory or storage means for coefficients for the correction of one and/or more basic characteristics of current and/or voltage sensors, with basic characteristics denoting static transfer-, temperature-, frequency-, load-, and position characteristics. |
