Abstract

Primary voltage uprating is done bi using a higher voltage in the primary distribution system. This is usually done to improve the overall performance of the distribution system. This study aims to analyze the primary voltage uprating of the electric cooperatives in the Philippines done by the National Electrification Administration through a standardized model. This model has the specifications of the electric cooperatives and follows the NEA Engineering Bulletin. The study focused on the evaluation of voltage drop of primary distribution, load reach, power capacity, system loss, and investment cost as the voltage is uprated from 13.2/7.62kV Y-grounded to 23/13.2kV Y-grounded. Results show that voltage drop and load reach governed by Ohm's law and losses governed by square of the current times resistance decreased as the current were reduced by a factor f V2/V1 (V1 is the existing voltage and V2 is the uprated voltage). On the other hand the power capacity of the system, given constant ampacity, increased by a factor of V2/V1. However, when primary voltage uprating is applied, the investment cost increases since transformers are needed to be changed. Given the evaluated electrical parameters, the primary voltage uprating will surely help the not profit-oriented electric cooperatives to improve their existing system. Thus, the electric cooperatives can save money and the consumers can be charged with appropriate rates.
