Abstract :
In the electric power operating system we always optimize the quality of service to customers. One of PLN's main performance indicators in the distribution sector is losses. At PT.PLN (Persero) Ampenan Customer Service Unit as one of the ULP in UP3 Mataram has a fairly large percentage of losses, which is 11.45%. The percentage of losses experienced is still above the standard (SPLN No. 10-1A: 1996, the tolerance for large losses is less and more than 10%). The cause of the high shrinkage is due to the length of the House Channel or SR that exceeds 5 house pulls, the load imbalance in each JTR phase where Line A (North) has a load imbalance of 18.6% and Line C (South) has a load imbalance of 18.6%. load imbalance of 36%, and the value of grounding on the neutral of the transformer which is still far above the PLN standard of 5%. Therefore, it is necessary to make improvements using the SR repair method that has exceeded 5 customer pulls, load balancing is done by moving some customer pulls to another phase, and improving the grounding value by adding a new groundrod on the transformer neutral and JTR pole
