Abstract
This research aims to find out how much influence the neutral current of the transformer at the
distribution substation has on losses and to find out how much influence the neutral current of the transformer at the
distribution substation has on losses.
This research used the literature study methods, survey methods and quantitative methods. The data analysis used
is the analysis requirements test, data normality test, data homogeneity test and data analysis techniques using single
regression analysis and coefficient of determination.
The results of this research show that the influence of the neutral current of the transformer, thereby increasing
the value of losses produced before load equalization, obtained at count = 8,611, a Sig value of <0.001 and a t tabel value
(df = 30-2, namely: to sides/0.025) obtained 1,701 (Appendix 5. T-tabel page 136) so that 8,611 & 1,701 and the
significance is < 0.001<0.05, while the result of analysis of the influence of the transformer neutral current thereby
increasing the value of losses produced after load equalization obtained a value of t = 5,374, the value Sig. <0.001 and the
t table value (df = 30-2, namely two sides /0.025) is 1,701 (Appendix 5. T-table page 136) so that 5,374 & 1,701 and the
significance is < 0.001< 0.05, so it can be concluded that there is an influence of current neutral transformer against
losses before and after load equalization. The result of the analysis of how much influence the transformer neutral current
has so that it increases the value of the losses produced before and after equalizing the load, it is obtained that the
coefficient of determination (R Square) is 0.726 and 0.508 and is interpreted as a percentage of the value of the neutral
current affecting the losses (power losses) before equalization. The load is 72.6% and 50.8% after load equalization and
remaining 27.4% and 49.2% are influenced by other variables.
