Abstract

This study used a DC voltage as source for SWER distribution system to further characterize the Lipa Soil Series. The line distance, depth of the grounding rods, resistance of the control load and the supply DC voltage were the independent variables considered in the study. The voltage drop on the line wire, the voltage drop on the load and the current passing through the system were determined in order to solve for the voltage drop on the soil by subtracting the line voltage and the load voltage from the voltage supply and perform an analysis on the voltage drop on the Lipa Soil Series. After all the data have been gathered and data transformations have been performed, statistical analysis was done. The researcher arrived at a best model under inverse power linear transformation which could explain 87.30% of the variance on the dependent variable VSOIL, was selected based on the highest value of the adjusted R2 equal to 0.8730. Test on normal distribution and residuals were conducted to confirm the validity of the best generated model. Through inspection of the equation and the graphs in the appendix, it can be deduced that VSOIL has a direct relationship with the VSOURCE and Distance and an inverse relationship Depth and RLOAD.
