Patent attributes
A voltage measurement apparatus is provided that includes: a potential attenuator configured to be electrically connected between first and second conductors, which are electrically coupled to a source, wherein the potential attenuator includes a first impedance and a reference impedance arrangement in series with each other, wherein the reference impedance arrangement has an electrical characteristic that can be changed in a known fashion; and further including a processing arrangement configured to acquire at least one signal from the reference impedance arrangement, the at least one signal reflecting change of the electrical characteristic in the known fashion; and to determine a voltage between the first and second conductors in dependence on the fashion in which the electrical characteristic is changed being known and the at least one signal.
