An electrical system quality is very important to develop and maintain for distributing the electrical energy to consument. The 20 kV medium voltage distribution system provides electrical energy to supply to the consument. However, but in the practical applications, there are many disturbances to supply to consument. The impact of short circuit disturbance on distribution network is too large, that could broke the equipment in distribution network, the losses on consument who live upon the electrical system, and can harm the people and make fire. This research was to calculate the asymmetrical short circuit currents that could occurred on the feeders and then the results would be compared to the simulations. They would also be used to set an OCR relay, to protect the feeders. The asymmetrical short circuit current calculation results were lower than those the simulations, with 403.9 A (9.24%) average difference, for two phase and 48.4 (12.53%) for one phase faults. The different of relay working times between the calculation and simulation results were 0.1913 s (45.98%) for the two and 0.0997 s (35.68%) for the one phase faults, where the latters were longer than those the formers.
