What is arc phenomenon in circuit breaker and how does arc produce?

March 20, 2017 by admin

Arc phenomenon When the contacts of a circuit breaker are separated, there is a luminous electric discharge between these two contacts known as ‘Arc’. This arc may continue until the discharge ceases. The production of arc may delay the current interruption process and generate emormous heat which may cause serious damage to system or to […]

What is circuit breaker and how does it work?

March 19, 2017 by admin

Introduction In earlier days, switches and fuses were placed in series to control (ON or OFF) the various circuits under both normal and abnormal (faulty) conditions. But the problem arises when fuse blows out it takes a considerable time to replace it and also not able to operate successfully under high voltage or have faults. […]
