Arua power system protection coordination study 
​(UGANDA)

​The project is a run-of-river type of hydro power generation. The power plant has a total installed capacity of 3.5 MW consisting of two units each rated at 1.75 MW. This resulted in the maloperations of the protective devices connected to the system for fault isolation and Reliability.
