It is foreseen that service and personal care wireless mechatronic systems will become more and more ubiquitous at home in the near future and will be very useful in assistive healthcare particularly for the elderly and disabled people. This paper describes the design and implementation of the micro controller-based system for protecting power. Transformer. The system includes facilities for discrimination between internal fault current and magnetizing imush current, differential protection, over current protection, over voltage protection and under voltage protection. In this paper, software and hardware of micro controller based system have been explained and designed. The design implementation and testing of the system are also presented.
