SF6 circuit breaker: One of the recent developments in the field of high voltage switchgear is the SF6 circuit breaker. In this a gas called sulphur hexafluoride is used as…
Non Linear Resistance Shunts: Non Linear Resistance are especially suitable, both from space and reliability considerations for small shunt currents in conditions where wire-wound resistors tend to be less satisfactory…
Linear Resistance Damping: By introducing a linear resistance across the circuit breaker during interruption, the restriking transients are damped. Provision has to be made for subsequent interruption of the resistance…
Air Break Circuit Breaker: The arc interruption process of Air Break Circuit Breaker is based on the natural deionization of gases by a cooling action. The arc is resilient and…
Duties of circuit breaker diagram: Under different circumstances Duties of circuit breaker diagram may be subjected to widely varying stresses. First of all the current varies from a few amperes…
Current Chopping: When interrupting small inductive currents such as transformer excitation currents, circuit breakers tend to clear before the natural current zero is reached. This is because the low-current ionized…
Characteristics of Rate of Rise of Restriking Voltage: The important Characteristics of Rate of Rise of Restriking Voltage which affect the circuit breaker performance are: amplitude factor, rate of rise…
