Abstract
Gangguan kelistrikan pada sistem transmisi dan transformator daya di gardu induk dapat menyebabkan pemadaman luas dan kerugian ekonomi yang signifikan. Di Kota Medan, Sumatera Utara, Gardu Induk 150 kV dan 275 kV menjadi bagian vital dalam penyaluran energi listrik sehingga proses pemantauan kondisi abnormal perlu dilakukan secara cepat dan terukur. Penelitian ini merancang dan mengimplementasikan sistem telemetering berbasis Internet of Things (IoT) sebagai lapisan pendukung monitoring 1-fasa untuk mempercepat penyampaian informasi gangguan. Sistem yang dikembangkan memanfaatkan sensor tegangan, arus, suhu, dan komputasi Total Harmonic Distortion (THD), mikrokontroler ESP32, protokol MQTT, Node-RED, InfluxDB, Grafana, serta notifikasi pesan instan. Penelitian dilakukan melalui studi literatur, survei sistem eksisting, perancangan prototipe, implementasi perangkat keras dan perangkat lunak, serta pengujian kinerja berdasarkan latensi, keandalan transmisi, waktu deteksi, waktu notifikasi, peningkatan kecepatan penyampaian informasi, dan akurasi komputasi THD. Hasil pengujian menunjukkan latensi pengiriman data sebesar 124-128 ms, keandalan transmisi 100%, waktu deteksi kondisi abnormal 1 detik, dan waktu pengiriman notifikasi 2 detik. Dibandingkan baseline simulasi operasional 5 menit pada pendekatan konvensional, sistem menghasilkan peningkatan kecepatan penyampaian informasi sebesar 99,33%. Validasi komputasi THD tegangan menunjukkan rata-rata error 1,52% dibandingkan Fourier Analysis pada Microsoft Excel. Hasil tersebut membuktikan bahwa prototipe telemetering IoT 1-fasa yang dikembangkan mampu meningkatkan responsivitas monitoring, mempercepat peringatan dini, dan menyediakan data kualitas daya secara lebih terintegrasi.

Electrical disturbances in transmission systems and power transformers at substations may cause widespread outages and significant economic losses. In Medan City, North Sumatra, 150 kV and 275 kV substations are vital parts of the electricity supply network; therefore, abnormal-condition monitoring needs to be fast and measurable. This study designs and implements an Internet of Things (IoT)-based telemetry system as a supporting layer for single-phase monitoring to accelerate disturbance-information delivery. The developed system integrates voltage, current, and temperature sensors; Total Harmonic Distortion (THD) computation; an ESP32 microcontroller; MQTT communication; Node-RED; InfluxDB; Grafana; and instant-message notifications. The research was conducted through literature study, survey of the existing system, prototype design, hardware and software implementation, and performance testing based on latency, transmission reliability, detection time, notification time, information delivery speed improvement, and THD-computation accuracy. The test results show a data-transmission latency of 124-128 ms, 100% transmission reliability, 1 second abnormal-condition detection time, and 2 seconds notification delivery time. Compared with a 5-minute operational-simulation baseline in the conventional approach, the system improves information-delivery speed by 99.33%. The validation of voltage THD computation shows an average error of 1.52% compared with Fourier Analysis in Microsoft Excel. These results demonstrate that the developed single-phase IoT telemetry prototype improves monitoring responsiveness, accelerates early warning, and provides more integrated power-quality data.
