Monitoring Pengunaan Daya 3 Phase Dengan Notifikasi Berbasis Telegram

Voltage Monitoring, current, and power on the panel are a must because this monitoring can see the magnitude of the voltage, current, cos phi, and power on the load.  One of these monitoring is to determine the quality of electricity, such as drop voltage, low cos phi. In this era of technology, monitoring can be viewed using mobile, so users don't need to come to the panel and see the measurement results, users look at the smartphone device. In this research, a researcher will make a tool that can monitor electrical measurements in 3 phase panel using mobile on a microcontroller.  Data will process from the current transformer at 3 phase panel by the ESP8266 microcontroller to convert into three-phase voltage, current, and power figures.  The ESP8266 microcontroller which is equipped with wifi can be used for remote monitoring.  An android smartphone with a telegram software application will function as communicate via wifi with the ESP8266 microcontroller so that all measurement data can also be monitored on the smartphone. The reading of the electric power monitoring tool has an accuracy of 97.39%. This shows that the tool can function very well.
