Abstract :
Measurements of power-system three-phase transformer resonant frequencies under fault conditions are analyzed and related to the transient recovery voltage appearing across a fault-interrupting device. Frequencies and time-to-peak values are derived that can be used to establish test standards for interrupting devices.
