The increasing demand for reliable, efficient, and accurate electrical energy distribution has driven the adoption of more advanced monitoring and control technologies. This study aims to analyze the impact of replacing conventional transducers with digital power meters on the validity of energy measurement data, particularly focusing on the kWh meter used as a reference. An empirical study was conducted on distribution transformers by comparing two data samples using the statistical Z-test method—load profile data from the kWh meter and log sheet data from SCADA. The research also examines SCADA data before and after integration with digital power meters and smart kWh meters to evaluate differences in measurement accuracy. Furthermore, the study assesses the effectiveness of real-time data acquisition, improvements in data processing accuracy, and system interoperability. The results indicate that integrating SCADA with smart meters significantly enhances telemetering accuracy and eliminates deviation from actual energy measurements recorded by the kWh meter. This integration supports the development of a more modern, efficient, and digitally based electrical distribution system. Therefore, the study provides a meaningful contribution to the advancement of smart grid infrastructure in Indonesia and strengthens the implementation of digital energy monitoring systems within the power distribution network..
