Faults Protection Systems and Transients in Power Systems

Using the attached graphs for fuses and circuit breakers (as required), design a suitable protection system for a 12 kW load. The installation is supplied from a 400 V source having a measured impedance of 0.040 W that can be assumed worst-case. Your design solution should comprehensively include:
* relevant design calculations,

* details of the chosen protection system,

* the design outcomes,

* the implications for the circuit cables to be used,

* any assumptions made.

Please mark the graphs to illustrate the final outcome. All workings must be clearly shown.
