Return to ProjectsRemote Monitoring System Implementation on Power Transformers
Posted Jan 17, 2012 at 9:16 pm
Project Summary
The aim of the project work is to protect the distribution transformer or any other power transformer, burning due to the overload, over temperature and input high voltage. Normally most of the transformers are burning because of these three reasons; hence by incorporating this type of monitoring and control circuits, life of the transformer can be increased. In addition to the monitoring and control, information about these three parameters can be transmitted to the nearest electrical office where the maintenance staff of the electrical department can monitor the transformer continuously without going nearer to the transformer. For this purpose, radio communication is utilized in this project work, so that, due to what reason the transformer has been failed, at what time, when the power is resumed etc., can be monitored and this information can be stored in a computer at the receiving station. With the help of this kind of system, the maintenance staff of the department can have a continuous vigilance over the transformer.
Project Description
This is a innovative project work introduced in the field of wireless communication, in this project work micro-controller is used at the transmitting side, and computer is utilized at the receiving end. The advantage of using micro-controller is, efficient control of each parameter can be achieved. Similarly the advantage of using computer is, the received information can be stored effectively.
In this project work, for the demonstration purpose a small step-down transformer of 12V, 2amps rating at secondary is considered and these three parameters are carried over this small transformer. This transformer is known as TUT (Transformer under Test).
The transducers used in this project work is for monitoring the various parameters are, a) CT (Current transformer) is used for measuring the load current at transformer secondary. b) PT (potential transmitter) for measuring the line voltage at transformer primary. c) SL100 (semiconductor) is used as a temperature sensor for measuring the transformer body temperature or oil temperature.
The micro-controller used in this project work is INTEL/ATMEL 89C51 chip, which functions according to the program written and stored in it. The program is made in assembly language. Similarly at the receiving end, for the computer, the program is written in ‘C’ language and with the help of associated hardware, the information received through the A/D converter can be stored and facilitates the display of failure parameter at the transmitting end. The output of the computer, through the latch is used to drive the alarm, which energizes automatically, whenever the receiver receives failure information.
