| 摘要 |
The invention relates to a method for determining the quality of the voltage (U) and/or current of an energy supply device, wherein parameters (UEFF, f, H3, H5, GHV) of the voltage and/or current are continuously detected and the quality of the voltage (U) and/or current is determined from the detected parameters (UEFF, f, H3, H5, GHV). To make it easier to determine the quality of the voltage (U) and/or current using such a method, disconnections (A) of the energy supply device carried out specifically are detected according to the method of the invention. Parameters (UEFF, f, H3, H5, GHV) detected over the duration of the disconnections (A) are explicitly indicated as such. The invention also relates to an arrangement (7) for determining the quality of the voltage (U) and/or current of an energy supply device. |
