The art of achieving selectivity between incoming .

07.10.2019 · Go back to Content Table ↑ 2. Three identical incoming feeders. An even better current selectivity is achieved in the case of a short circuit on an outgoing feeder using n = 3 parallel-connected transformers, since the characteristic displacement factor for the incoming feeder circuit-breakers Q1, Q2 and Q3 is then in the range 2 < K t-I ≤ 3 (for an idealized example, see Figure 2a).
