PT. PLN (Persero) will always strive for the maintenance of existing network equipment in the distribution network of electric power that can operate optimally. The problem is that they often do the shutdown for maintenance, repair, and network expansion. Mechanical work like this is a problem, because it causes harm to consumers and the power company itself. For consumers losses incurred is not continuity of service distribution of electricity, while for PLN kWh produced no bias channeled. The method used in the maintenance of the air duct in a state voltage using touch labor, working methods within and working methods of potential. Before doing work in a state-voltage, first need to do a feasibility study of investment-voltage equipment, one of the economical aspects. The method used is NET Present Value, Internal Rate Of Return and Net Benefit Cost Ratio, so it can be a large degree of benefit obtained with the maintenance voltage. With the PDKB, PT PLN (Persero) Rayon Kuta can save rupiah amounting Rp.8.941.763.694 kWh per year. SAIDI is pressed is 991.8122431 minutes / customer / year, for SAIFI is 14.60000046 minutes / customer / year. the number of jobs between direct touch method and is, from a total of 575 189 jobs within the job using the method and 386 using the touch method directly. Net Present Value positive value of Rp.27.347.312.169 means cash inflows greater than the cost of investment, Internal Rate Of Return obtained amounted to 18.111% greater than the desired rate of return, Net Benefit Cost Ratio is greater than 1. Thus voltage maintenance work is technically and economically profitable so it is feasible.
