Define:

a) SF6 Circuit Breaker

b) Ferranti effect

E

Expert

Verified

SF6 :

SF6 refers to Sulpher hexa Fluoride gas. If this gas is used as the arc quenching medium within the Circuit breaker it means SF6 CB.

Ferranti effect :

Output voltage is larger in comparison to the input voltage or accepting the end voltage is more than sending the end voltage.
