Abstract

The electric performance and the economics of four supply options for a specific 12.5-kV radial distribution feeder were examined. Options included upgrading to 34.5 kV and/or sectionalizing. Feeder losses, voltage regulation, and system voltage dips due to feeder faults were analyzed. It was found that distribution transformer losses were a significant component in the total feeder loss and an important factor in the loss comparison of the two voltage levels. In this case, sectionalizing the existing feeder at 12.5 kV was the preferred option based upon cost, system voltage dip performance and ease of back feed.
