Power distribution equipment systems (PDES) are critical for reliable electricity supply in Tanzania's rural areas. A randomized field trial was conducted to evaluate the reliability of PDES, employing statistical models to quantify risks. The trial results showed that PDES with redundancy features reduced power outages by approximately 20% compared to non-redundant systems. The study confirms the efficacy of incorporating redundancy in PDES for enhanced reliability and risk reduction. Implementing these findings could lead to more resilient power grids, reducing costs and improving service delivery in Tanzania's rural regions.
