...A capacitive voltage divider, which uses capacitance for impedance, is used to measure high AC voltage. A device that constantly monitors the voltage at each point in a power system is the PD (short for potential device, also known as a capacitor-type instrument transformer), which combines a capacitive voltage divider and a low-voltage measuring device. ... *Some of the terminology that mentions "potential device" is listed below.
