13. MCCB2 Downstream Downstream Fault 1 Current Fig 2 Discrimination Using discrimination the system maximize the continuity of service While the fully rated method requires each circuit breaker must have higher breaking capacity than the prospective short circuit current at the point of installation the discrimination requires that as only the circuit breaker nearest the fault is opened to interrupt the fault the upstream breaker must have short time delay characteristic The upstream breaker must not be tripped and withstand against the thermal and electro dynamic stress passed through the breaker nearest the fault until the clearing it The disadvantage of discrimination compared to the cascading or the fully rated method is in the initial installation costs The cost for the total discrimination can be reduced to some extent by using partial discrimination There are different techniques to approach to implement this discrimination The Current discrimination is the technique using the difference between the trip thresholds of the breakers the Time discrimination using trip delaying and the Energy based discrimination using arc energy 1515 Electric Equipment 28 29 Current discrimination The Current discrimination is the technique using the difference between the instantaneous or short time current trip thresholds of the breakers in series The maximum trip thresholds of the downstream breaker should be less than the mini
