PT PLN (Persero) assign (SPLN 1: 1995) which states that the tolerance limit allowed for a rated voltage is + 5% and -10% of their nominal value. The greater the demand load and load conditions are unstable and the distance between the location of the center load distribution channeling much lead to problems in the distribution of electrical power, especially voltage drop problem. In this final project discussed voltage drop occurs in Department A Distribution Substation DB108G and improvements with the construction of substations inserts using v.16.0.0 ETAP simulation applications. From the results of inspections of tip voltage obtained percent voltage drop of 9.90%, which is already close to the limit of tolerance SPLN 1 : 1995 which amounted to + 5% and -10%. After simuating repairs using the ETAP application, the voltage quality becomes more optimal and still within the tolerance limit of SPLN 1 : 1995, which is + 5% and -10%.} }
