Abstract

The Effect Of Loading On The Power Capacity Of A 1-Phase 50 Kva Distribution Transformer. The 50 kVA distribution transformer at the SNT04-109 substation plays an important role in distributing electrical energy to customers. However, increasing loads can accelerate the decline in transformer performance and lifespan. This study aims to analyze the effect of loading on transformer power capacity using a descriptive quantitative approach based on load current data from 2019 to 2023. The results show that the average nighttime load current increased from 96 A in 2019 to 131 A in 2023. Based on calculations, the actual power carried has reached 28.9 kVA or 72.2% of the maximum capacity. With an annual load growth trend of around 8.7%, it is estimated that transformers will experience overloading in the coming years. If load management or uprating is not carried out, the risk of damage and decreased operational efficiency will increase. Therefore, routine monitoring and capacity planning are essential to maintain the reliability of electricity distribution.

Abstract

This Study Aims To Analyze The Effect Of Loading On The Life-Time Of A 50 Kv Distribution Transformer at Penyulang LMS01, Tambakreja Village, ULP Cilacap Kota. Distribution transformers are critical components in power systems, and overloading can accelerate performance degradation and reduce their lifespan. The research method involves measuring current, voltage, and load power of a B&D transformer from 2019 to 2023. The analysis reveals that excessive loading, especially during nighttime, reduces the transformer's lifespan by 8 years and 9 months from the standard 20 years, with an error value of 44,25%. The remaining lifespan is estimated at only 11 years and 3 months. This study recommends regular monitoring and limiting loads to below 80% capacity to extend the transformer's operational life.
