Internet Voltage-Based Voltage Protection Design (IoT) Using ESP32: A Comprehensive Guide

Introduction

The Internet of Things (IoT) has revolutionized the way we live and work, and its applications in the field of electrical engineering are no exception. One of the most critical aspects of electrical engineering is voltage protection, which ensures the stability and safety of the electricity system. In this article, we will discuss the design of an IoT-based voltage protection relay using the ESP32 module, which offers innovative solutions in maintaining the stability of the electricity system.

Voltage Protection Relay Work System

The voltage protection relay utilizes the ESP32 module as the main microcontroller for data processing and communication with the Blynk application on mobile and Arduino Promini. Arduino is used to read the phase and voltage sequence data from the ZMPT101B sensor. After the data is processed, ESP32 will send the trip command to the release control module if certain conditions are met. In other words, if there is an excess condition or voltage deficiency, this system will automatically cut off electricity to prevent damage to the equipment.

The system works as follows:

The ESP32 module reads the input voltage from the ZMPT101B sensor and compares it with the regulated voltage.
If the input voltage is within the specified limit, the relay remains active, and the electricity continues to the load.
If the input voltage exceeds the specified limit, the ESP32 module sends a trip command to the release control module, which cuts off the electricity to prevent damage to the equipment.

Features and Ease of Settings

One of the advantages of this design is its ability to set up through the TFT LCD screen or through the BLYNK application on mobile phones. Users can adjust the voltage limits, delay time, and the percentage of voltage imbalance easily and quickly. In addition, users can also monitor the voltage between phases, phase-netral voltage, and graph of the voltage reading in real time.

The features of this design include:

Easy setup through TFT LCD screen or BLYNK application on mobile phones
Adjustable voltage limits, delay time, and percentage of voltage imbalance

In this relay design, the reading tolerance reaches ± 5% in accordance with the practice of IEEE recommendations for monitoring the quality of electrical energy. Data shows that the error rate in the delay is 3.62%. This shows that although there is a possibility of error in measurement, this system can still function properly and provide the protection needed in various electricity situations.

The accuracy and tolerance of this design are as follows:

Reading tolerance: ± 5%
