Abstract :
Capacitive-coupled amplifier-type voltage transformers are described that are used to measure voltages in metal-clad h.v. switchgear. The stack capacitor of an active voltage divider forms a part of the switchgear itself. Tests and long-term experience in substations show the accuracy and long-term stability to be better than 0.2%. Tests on the dynamic performance are discussed.
