Almost a hundred percent of Bangladesh's population has access to electricity, and the country's generation capacities have expanded rapidly over the past few years. However, due to the poor distribution system, the reliability and quality of the delivered power remain significant concerns, and people still face interruptions in the power supply. Bangladesh's vision is to improve power quality and maintain uninterrupted electricity service by 2030. As distribution system faults are responsible for the majority of interruptions, this study focuses on detecting and analyzing the fault types and the timing of their occurrence. Two substations operating under the largest distribution company of Bangladesh REB from separate locations are selected for analysis purposes. And the result shows that half of the faults are L-G faults and around 35% of faults are L-L-G faults. If these faults can be minimized, the amount of interruption will be an acceptable rate. A set of recommendations is also brought out that can be used to minimize these faults. This paper aims to represent Bangladesh's current distribution network scenario.
