Abstract
A combination of a conductor, such as a busbar, and a device for measuring the AC voltage in the conductor, which device includes: an insulation layer arranged on the conductor; a capacitor plate arranged on the insulation layer and configured to position the capacitor plate at a fixed distance from the conductor to form a first capacitor; a second capacitor arranged electrically between the capacitor plate and ground to provide a capacitive voltage divider with the first capacitor; and a voltage measurer for measuring the voltage at the capacitor plate, the voltage measurer including a frequency measurer for measuring the frequency of the voltage in the conductor and an AC voltage calculator for calculating the AC voltage in the conductor based on the capacities of the first and second capacitors, the measured voltage, and the measured frequency.
