Computerised temperature rise test for low power transformer using solid state devices / Nizar Khan Sar Khan

The usage of computer provides indispensable factor in minimising labour. This project will study on how the computer can be used in implementing the temperature rise test on a typical dry type transformer. The purpose of this project is to design the hardware and develop a computer software to conduct a temperature rise test on a dry type transformer. In this part of the project, the developed circuit which consist of temperature sensor will detect temperature winding and send it to the computer through interfacing. The software has been programmed to receive the signal from the hardware and plot a suitable graph, finally the computer will cut off the power to transformer if the requirement of the test have been satisfied, and gives temperature rise result The software has been develop using Borland C++. This will allow the users to easily understand the operation of the software and make any changes or upgrade the whole system.
