Web28 i =is +it = [ 2V/Z] sin ( t+ - ) + [ 2V/Z] sin ( - ) e(-R/L)t (2.9) Thus, is is the sinusoidal steady state current called as the symmetrical short circuit current and it is the unidirectional value called as the DC off-set current. This causes the total current to be unsymmetrical till the transient decays, as clearly shown in figure 2. WebJun 23, 2024 · is low enough to be thought of as essentially symmetrical. The symmetrical current test found in IEEE C37.09 for MV circuit breakers is called T100s and it is used to prove the Standard Operating Duty for a circuit breaker. The test requires 100% of the rms symmetrical current rating and indicates that the asymmetry should be less than 20%.
