Efektivitas Penormalan Modem Automatic Meter Reading (AMR) pada kWh Meter 3 Fasa

Abstract

     Abstract

The implementation of an AMR system on three-phase kWh meters can improve the efficiency of monitoring, recording, and managing customers’ electricity consumption data automatically, transmitting it from the kWh meter to a server through a specific communication network, namely the internet. However, during implementation, error disturbances are still found in the AMR modem, which can cause measurement inaccuracies in the AMR system. This may result in inaccurate electricity billing for customers and erroneous reporting, leading to losses for the company. The normalization process is carried out in several stages, starting from fault notification through to the commissioning test stage. Physical inspection of the modem, measurement of the supply voltage, signal quality checking, SIM card inspection, network connection testing, reconfiguration of communication parameters, device reset, and replacement of damaged components—along with the restoration of smooth communication between the kWh meter and the AMR device system as indicators of the successful normalization of the AMR modem for various causes of disturbance. The research results show that the effectiveness of the AMR modem normalization process reached 92.3% out of 220 fault cases that occurred during the research period. AMR modem faults were mostly caused by modem damage, SIM card problems, modem configuration errors, and environmental factors. The normalization process is considered successful when the AMR system can obtain various measurement data from the customer’s kWh meter, including voltage, current, electricity consumption, and other variables such as customer ID, location point, modem type, SIM card number and type, and IP address.

Abstrak

Penerapan sistem AMR pada kWh meter 3 fasa dapat meningkatkan efisiensi monitoring, pencatatan, dan pengelolaan data konsumsi energi listrik pelanggan secara otomatis dari kWh meter ke server melalui jaringan komunikasi tertentu yaitu internet. Namun, dalam pelaksanaannya masih ditemukan gangguan error pada modem AMR yang dapat menimbulkan ketidakakuratan pengukuran pada sistem AMR sehingga dapat  berdampak  pada  biaya tagihan Listrik yang tidak akurat kepada pelanggan serta pelaporan salah yang menyebabkan kerugian bagi perusahaan. Proses penormalan dilakukan dengan beberapa tahapan yang dimulai dari notifikasi gangguan sampai pada tahapan commissioning test. Pemeriksaan kondisi fisik modem, pengukuran tegangan suplai, pengecekan kualitas sinyal, pemeriksaan kartu SIM, pengujian koneksi jaringan, konfigurasi ulang parameter komunikasi, reset perangkat, penggantian komponen yang mengalami kerusakan serta kelancaran komunikasi antara kWh meter dan sistem perangkat AMR dapat kembali berfungsi normal menjadi indikator keberhasilan proses penormalan modem AMR dari berbagai penyebab gangguan. Hasil penelitian menunjukkan efektivitas tingkat keberhasilan penormalan modem AMR mencapai 92,3% dari 220 kasus gangguan yang terjadi selama proses penelitian. Gangguan modem AMR banyak disebabkan oleh kerusakan modem, permasalahan pada karu SIM, kesalahan konfigurasi moden, dan faktor lingkungan. Sedangkan proses penormalan dinyatakan berhasil apabila sistem AMR dapat memperoleh berbagai data pengukuran dari kWh meter pelanggan yang meliputi besar tegangan, arus, pemakaian daya listrik serta variabel lainnya seperti id pelanggan, titik Lokasi, jenis modem, nomor dan jenis kartu SIM dan ip address.
