Analysis on Fault Failure of Automatic Meter Reading System on Hardware Devices

Abstract

The Automatic Meter Reading (AMR) system is an indirect measurement system used by PT PLN (Persero) to facilitate the monitoring of customer electricity usage. Electricity usage measurements determine the revenue of electricity providers. Manual data reading errors and device malfunctions are the main complaints customers have against electricity providers. The AMR system has been implemented for many customers, and its presence can reduce irregularities. Irregularities that occur in AMR can generally be divided into two types, namely irregularities due to serial communication failures that need to be repaired, and technical irregularities where energy is not measured optimally. The use of the FMEA analysis method is expected to identify, determine, reduce, and eliminate failures and potential failures from the process before these failures reach customers. Based on the FMEA analysis results, corrective actions in the form of hardware replacement on components with the highest Risk Priority Number (RPN) proved effective in reducing the RPN value after the repairs were made, thereby increasing the reliability of the AMR system and minimizing the potential for electricity reading disruptions.
