Enhancement of Selective Coordination for Samar State University Electrical Power System
Keywords:
Enhancement, Coordination, Samar State University, Power SystemAbstract
The main purpose of this study was to assess the selective coordination of (3)- three phase electrical power system of Samar State University main campus. The study employed quantitative descriptive research design. Quantitative since the study aimed to identify and calculate extent of actual operational capabilities of existing Samar State University electrical power system in terms of selective coordination of protective devices, service entrance, feeder conductors, its respective rating and capacity if subjected overloading. Power consumption of the university increased in the last eight (8) years starting from year 2010 up to 2017. The maximum connected load utilized is equivalent to 2,767, 689 kW-Hr; average is 345, 960 kW-Hr and the lowest is 287, 600 kW-Hr. Overloading is the core problem in Samar State university electrical power system for the past eight (8) years. Administration replaced the damage transformer, the potential cost of damage was Php 278,250.00. The power loading of the electrical system reached up to 1,070. 565 kW in total. The increase of energy consumption of the university should be considered as one of the indicators for electrical system enhancement. Electrical overloading is a recurring problem in the electrical system as a result of load expansion. Electrical system is in a state of active failure. For the recommendation, enhancement of Samar State University electrical power system is needed starting from the first private pole, transformer up to branch feeder circuit supplying per building.
