AIM:
The main aim of this project is to use the RF technology to continuously monitor and control the distribution transformer or any other power transformer from burning due to the overload, over temperature and high input voltages.
PURPOSE:
Normally most of the transformers are burning because of over load; hence by incorporating monitoring and control circuits, correspondingly increasing the life time of the transformer
DESCRIPTION:
In this project we designed a system in such a way that it will monitor and control the load of the substation continuously and that information is transferred to the control room using RF Technology. In the main station these parameters are displayed on the PC. In PC we can view the continuous information of transformer i.e. due to what reason the transformer has been failed, when the power is resumed etc.,. With the help of this kind of system, the maintenance staff of the department can have a continuous vigilance over the transformer.
In this project work, for the demonstration purpose a small step-down transformer of 12V, 1 amps rating at secondary is considered and small bulbs are connected as a load. In this project we are using CT transformer for measuring load current, voltage sensor and temperature sensor. All these parameters are converted into digital value by using ADC. If the parameters of the transformer regain the limited range values then Transformer will automatically shutdown. Microcontroller near the transformer section will continuously transmit all the parameters of the transformer to control room and it will be displayed on PC.
