The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch.
The main task of a circuit breaker is to interrupt fault currents and to isolate faulted parts of the system. A circuit breaker must also be able to interrupt a wide variety of other currents at system voltage such as capacitive currents, small inductive currents, and load currents. It is reliable in its operation.
to use low energy spring operating mechanisms for the operation of high voltage circuit breakers. Self blast type of circuit breakers have progressively replaced puffer types, from 72.5 kV up to 800 kV. For longer distances between electrodes, a higher voltage withstand is obtained with SF6. Vacuum is mainly used for MV circuit breakers.
A circuit breaker must also be able to interrupt a wide variety of other currents at system voltage such as capacitive currents, small inductive currents, and load currents. It is reliable in its operation. These circuit breakers are also called LIVE TANK as the chambers are at system potential. good seismic withstand.
Vacuum is mainly used for MV circuit breakers. A circuit breaker must have a short-circuit making current capability. The capability to make the rated short-circuit current demonstrated by performing the following closing operations. one with an asymmetrical current with the required peak current (IEC and IEEE).
IEEE application guide for AC high voltage circuit breakers rated on a symmetrical current basis IEEE std. C37010-1999. First step in carrying out short circuit studies is to determine system impedances with reference to the point of fault and current distribution for different kind of faults.
Circuit breakers to be used in cable systems are of class S1. Circuit breakers to be used in line systems are of class S2. A test circuit having the standard DC time constant (45 ms) would give the correct conditions for current interruption: peak and duration of the last major loop of current, slope of current (di/dt) and TRV.
