Modified Differential Protection of Generators

The most common schemes employed for the protection of a three-phase generator stator windings from earth faults phase-to-phase faults make use of circulating current principle.   In these protection schemes, currents at the two ends of the protected section are compared. Under normal conditions, these currents are equal became different on the occurrence of a …

SF6 Circuit Breaker

Hi friends, in this article, I am describing the SF6 circuit breaker construction and working principle. This article will increase your knowledge; I hope so. In the oil circuit breakers, air circuit breakers and low oil circuit breakers, arc extinction take place slowly after the moment of contact separation. Hence, the arc is usually extinguished …
