Abstract
An adaptive voltage divider for measuring a high voltage between a ground terminal (GND) and a measurement terminal (U). It comprises a first branch comprising a first set of impedance elements (Z, R) forming a voltage divider circuit connected between the ground terminals (GND) and the measurement terminal (U) and a voltage meter (AD2) configured to measure voltage on one of the impedance elements (Z, R) of the first branch. Furthermore, it comprises a second branch comprising a second set of impedance elements (Q, P) connected between the ground terminal (GND) and the measurement terminal (U) and switchable between a plurality of configurations, wherein in at least one configuration the second set of impedance elements (Q, P) forms a voltage divider circuit, and voltage meters (AD1, AD3) configured to measure voltage on at least one of the impedance elements (Q, P) of the second branch. Moreover, a control circuit (DCSS) is configured to consecutively switch the configuration of the second branch between the plurality of configurations thereof, such that the relationships between the values of impedance elements (Z, R) of the first branch and the values of impedance elements (Q, P) of the second branch can be determined for consecutive configurations of the second branch as a function of the outputs of the voltage meters (AD1, AD2, AD3) and the total transmittance of the voltage divider can be determined at any instance as a function of the outputs of the voltage meters (AD1, AD2, AD3).
