Microprocessor Semantic Scholar An interrupt driven overcurrent relay for power systems using the 8085 microprocessor is presented. the relay requests processing time from the microprocessor only when a fault occurs. Pdf | this work presents the design and implementation of a versatile digital overcurrent (o c) relay using a single microprocessor.
Figure 2 From Microprocessor Based Overcurrent Relays Semantic Scholar Abstract: the authors describe the design of a microprocessor based overcurrent relay that is suitable for protecting distribution and subtransmission networks. This paper presents electromechanical and microcontroller based over current protective relays for electric distribution feeders. the objective is to determine the reliability of the system by comparing the performance of electromechanical and. In section 2 of this paper the authors have critically examined the usage of overcurrent relays, accentuating the circumstances in which each type of relay should be used. Current is taken from c.t. and given to i to v converter because many electronics circuit require voltage signal for operation. the a.c. voltage is converted into d.c. voltage by using rectifier. this d.c. voltage is proportional to load current only. the output of rectifier is given to multiplexer.

Leveraging this paradigm shift, we propose a novel approach that integrates iot capabilities with microprocessor based over current relays. this fusion of technologies aims to enhance the efficacy and versatility of power system protection mechanisms. There are two types of overcurrent relay depends on the types of the relay which are: delayed or instantaneous type the delay type may be time inversely proportional to the magnitude of a current or fixed time. figure 1 shows the different types of overcurrent characteristics [3]. This work presents the design and implementation of a versatile digital overcurrent (o c) relay using a single microprocessor. the relay is implemented by a combination of a look up table and a counter. The aim of this research is to test the feasibility and performance of microprocessor based ocr with fuzzy logic control in setting tms values, and compare it with the international standard iec 60255.
