Rancang Bangun Sistem Kendali pada Panel Hubung Bagi Tegangan Rendah

Abstract

The rapid development of technology has become an integral part of human life, bringing us into the digital era with significant impacts on various sectors, including the electric power distribution system. The Low Voltage Distribution Panel (PHB-TR) is an essential component in the electric power distribution system, responsible for controlling and distributing low voltage to end consumers. However, this equipment is vulnerable to technical disturbances and human sabotage, which can lead to prolonged problem resolution and material losses. This study explores the design of a monitoring and control system for PHB-TR based on ESP32, integrating Internet of Things (IoT) technology. The system uses Limit Switches and PIR sensors to detect disturbances and provide real-time notifications via Telegram. The Limit Switch is installed in Normally Closed (NC) mode to detect status changes when the panel door is opened, while the PIR sensor detects movement and activates a buzzer as a warning signal. System testing includes network connectivity, Limit Switch functionality, and Telegram notification delivery, as well as PIR sensor functionality and control through the Blynk application. The test results show that the control system on PHB-TR works well, with Telegram notifications successfully sent when the panel door is opened and the PIR sensor effectively detecting movement. The application of this system improves the reliability of power distribution with a quick response to disturbances, thus minimizing losses and ensuring a reliable power supply
