En metod och ett don för spänningsmätning |
摘要 |
Measuring equipment for forming a measured value for voltage representing an ac voltage on a high-voltage conductor. The measuring equipment includes capacitor equipment with a known capacitance for connection between the high-voltage conductor and ground potential. The measuring equipment further includes a current-measurer for sensing a capacitor current flowing through the capacitor equipment and for forming the measured value for voltage in dependence on the capacitor current. |
