Abstract
This project represents the automated and manual watering system for substation earthing using sensors for electric safety. This project describes about the safety precautions for earthing. This project consists of various types of sensors used in the project that is rain sensor, float sensor, moisture or capacitive sensor.
The ESP 32 Microprocessor used in this project consists of high-resolution system that has large capacity code storage. It has wifi connectivity system. This makes it more reliable than ATmega 32 microcontroller. This microcontroller consists of IOT (internet of things) that is more reliable. Project has seven segment display to improve manual control for watering. The earthing is the most important factor in the electrical system. In this project main focus is earthing in a 33/11 kV substation.
ESP 32 Microprocessor consists of power supply that is SMPS switch mode power supply. The project consists four earth pits used for earthing. The main purpose of our project is to maintain the earth resistance. The earthing resistance must be less than 5 ohms. So, in this project we maintain the earthing resistance via soil moisture sensor and also float sensor.
