High Frequency Arc in VacuumArc ModelWhen re-ignition occurs at reactor current interruption, high frequency current flows through the circuit breaker.In case of the interrupting the high frequency current, it is known the occurrence of the multiple re-ignition and voltage escalation.The high ...
The working of an SF6 circuit breaker is similar to theworking of a normal circuit breakerwe discussed in previous articles. In the closed position of the breaker, the contacts remain surrounded by sulphur hexafluoride gas (SF6) gas at a pressure of about 2.8 kg/cm2. When the breaker oper...

Effect of vacuum arc cathode spot distribution on breaking capacity of the arc-extinguishing chamber A DC circuit breaker performs a key function in breaking an intermediate-frequency (IF) current since breaking a pure IF current is equivalent to breaking a very small DC with a reverse IF current...
However, this isn’t the fault of the breaker and should be resolved by properly running the circuits.The bigger problem, and one I see very often is nuisance tripping from incompatible electronic devices. Devices like vacuum cleaners, hair dryers, treadmills, and many small appliances can ...
