Abstract  The paper deals with experimental monitoring system, developed by the authors, by using a microcontroller within the 8051 family, Dallas DS87C550. This micro-system has two main parts: the acquiring and transfer module and the user interface developed using the facilities specific to Graphic User Interface of Matlab®. The achievement such a way implies designing a hardware structure that meets the proposed … Continuă lectura Modern Techniques for Monitoring Circuit Breakers by using Microcontroller System
