Abstract :
To ensure continuity and reliability of electricity distribution, maintenance is carried out.
However, this maintenance is still often done blackouts. The maintenance system or
substation revision carried out by PT. PLN (Persero) UP3 Marunda Area which was
carried out by extinguishing distribution substations which resulted in blackouts to
customers during the maintenance work. This is a concern because customers feel
blackouts which will have an impact on kWh sales, an increase in ENS (Energy Not
Suplied) and an increase in the SAIDI (System Average Interuption Duration Index) value
which will be even greater. To reduce this, PT. PLN (Persero) UP3 Marunda Area applies
a maintenance system with a non-extinguishing method or by carrying out work in a
voltage state (PDKB) by moving the load of the substation that will be carried out for
maintenance to the Mobile Substation Unit (UGB) or Mobile Transformer Unit (UTB).
The research was conducted using quantitative methods, namely research procedures that
produce data in the form of numbers that can be analyzed. In the calculation of the energy
saved at the BK196 substation is 61.83 kWh, at the PK165 substation it is 141.98 kWh
and at the CK190 substation 63.25 kWh. The minimum extinguishing method at the
BK196 substation is 46.37, at the PK165 substation it is 106.48 and at the CK190
substation 47.38 kWh. This proves that the application of maintenance with the nonextinguishing method can save energy that is not channeled by 66,772 kWh with a rupiah
rotation of Rp. 97,954.52/month. The SAIDI value is smaller when implementing a
maintenance system with a minimal outage method of 03 minutes/customer/year than a
total outage of 1.2 minutes/customer/year.
