| Parameter | Description | Formula / Definition | Notes |
|---|---|---|---|
| Discrimination Selectivity Protection (DSP) | Ensures selective tripping of downstream MCCBs without affecting upstream breakers | N/A (Conceptual protection scheme) | Prevents unnecessary power outages by coordinating breakers |
| Time Selectivity | Downstream breaker trips before upstream breaker by time delay | Tupstream > Tdownstream + ΔT | ΔT = safety margin (typically 0.2 to 0.5 seconds) |
| Current Selectivity | Downstream breaker trips at lower fault current than upstream breaker | Itrip downstream < Itrip upstream | Ensures only closest breaker to fault trips |
| Energy Let-Through Coordination | Coordination of I²t values to prevent upstream breaker tripping | I2tupstream > I2tdownstream | Helps in discrimination during short-duration faults |
| Selectivity Ratio | Ratio of upstream to downstream breaking capacities | SR = Icu upstream / Icu downstream | Ideal SR > 1 for effective discrimination |
