Abstract

This study aims to analyze the effectiveness of kWh meter maintenance as an effort to reduce non-technical losses in the electricity distribution system at PT. PLN (Persero) ULP Panarukan. Non-technical losses, which are often caused by meter inaccuracy, recording errors, and illegal usage, have a direct impact on the company's revenue. Using a quantitative descriptive approach, this study compares the level of non-technical losses before and after the implementation of a structured kWh meter maintenance and replacement program. Data were collected through field observations, interviews, and documentation from PLN's internal systems (ACMT, AP2T, EIS). The results show that maintenance activities successfully improved measurement accuracy, which led to a decrease in unrecorded energy. Thus, non-technical losses were reduced and resulted in significant financial savings. In addition, the study proposes an age-based meter replacement Operational Target (TO) as a strategic framework for determining maintenance action priorities. It is concluded that optimizing the maintenance program for aging kWh meters is a crucial operational step in controlling non-technical losses and securing PT. PLN's revenue.

Abstract

Electricity is a vital component in supporting activities across various sectors, particularly in industry. The reliability of the power distribution system is crucial to maintaining the continuity of energy supply. However, during the distribution process, power losses (technical losses) frequently occur, primarily due to load imbalance in distribution transformers. This study aims to analyze transformer loading on the JN 05 feeder at ULP Janarata by calculating the load percentage, phase current imbalance, and power losses caused by neutral current. A quantitative approach was used, based on field measurements of 16 transformers under Peak Load Conditions (WBP) and Off-Peak Load Conditions (LWBP). Prior to load balancing, total power losses due to neutral current reached 10,190.37 kWh during LWBP and 3,733.41 kWh during WBP each month. After load balancing was performed between phases, technical losses were reduced by 13,923.77 kWh per month. These results indicate that load balancing is an effective method to reduce power losses and improve the efficiency of the distribution system.
