They originate in switching and fault clearing process.Ĥ. They are temporary over voltages of power frequency or its harmonic frequencies. Switching over voltages are highly damped short duration over voltages. Switching over voltages originate in the system itself by the connection and disconnection of circuit breaker contacts or due to initiation or interruption of faults. How are switching over voltages originated in a power system? What are the chief causes of over voltages in electric power system?ġ) Lightning over voltages (Natural causes)Ģ) Switching over voltages (system oriented causes)Ģ.
