Abstract :Electricity plays a vital role in the modern world, and secure distribution to end-users heavily relies on distribution transformers. Designed to last up to 30 years, transformers often suffer from early failure due to factors like moisture, equipment mishaps, and especially overloading. This study focuses on Pampanga II Electric Cooperative, specifically Feeder 4 of the Pio Substation in Porac, Pampanga. Feeder 4 serves over 8,400 residential consumers and operates 100 Commonly Used distribution transformers. The study assessed and identified transformer failure causes and rates of occurrence, categorize loading conditions and examined their relation using 2023–2024 data through a quantitative approach. Of the 100 units, 34 failures occurred in the said period. Causes such as the overloading and equipment failure show that most transformers are categorized as overloaded. In summary, overloading transformers significantly contributes to failures within the Pampanga II Electric Cooperative system. The findings imply the need for better management of transformer loads. The optimal loading conditions increase efficiency and extend their lifespan, which in turn reduces power outages and maintenance costs. This situation benefits both utilities and consumers, as it ensures a more stable and reliable power supply.
