| 摘要 |
The invention relates to a compensation circuit for the phase shift between a first input (3) for a voltage determination and a second input (4) for a current determination in electric meters for direct connection, whereby a DC-tolerant converter (5), for current transformation, is arranged before said second input (4) and a high pass filter (R1, C) is arranged before the first input (3), for a first equalisation of the non-frequency-dependant phase compensation. A further equalisation of the phase compensation occurs by means of a correction device (5) in a measuring chip (2), which is connected in series with the inputs (3, 4) for voltage determination and current determination. |
