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…
Restriking Voltage Transient: Electrically a power system is an oscillatory network so that it is logical to expect that the interruption of fault current will give rise to a transient,…
Circuit Breaker Rating: The ratings of a circuit breaker refer to the characteristic values that define the working conditions for which the circuit breaker is designed and built. Circuit breakers…
Coincidence Type Phase Comparator: The basic concept of phase comparison is simpler in that it is possible to deal with signals of equal strength whose coincidence (or noncoinecidence) is readily…
