Abstract

Proper rating of transformer is important in maximize the useful life and efficiency of the equipment. A higher or lower rating of the transformer can provide either a higher system loss or disconnection of consumer connectivity of electricity. In this study, assessment of residential transformer of a barangay was considered. The percent loading of each transformer was evaluated by the used of the standard set by National Electrification Administration (NEA). Software used in the study is Microsoft Excel 2016 for determining the percent loading of each residential transformers. After the percent loading was identified, clustering of transformers was made according to the loading conditions.  Changing of Rating were also performed to corrected the percent loading of the transformer. From 2017 to 2019, 13 transformers or 48.14 % were underloaded while 6 or 22.22% were found to be overloaded. Changing of the rating of the transformer in the barangay, the percent loading of the 6 overloaded transformers were corrected. For the 13 underloaded, 12 of which were corrected. Also, in the underloaded there is still a unit RT19 that is in underloaded even changing the rating due to the available lowest rating of the transformer was reach. Installing the proper rating of the transformer can save 303,955.30 Php by comparing the old rating to the new rating. The researchers recommend to use load centering to minimize the number of the transformer. Another is the monitoring of kWHr of consumer in a daily basis by the use of Automated Mapping/Facility Management/ Geographical Information System or AM/FM/GIS to identify the peak load of each transformer, compare to the monthly kWhr.
