Arduino-Based Overcurrent Relay Design with Very Inverse Type
Journal Title: International Journal of Current Science Research and Review - Year 2024, Vol 7, Issue 11
Abstract
The protection system is a very important system in the electric power system, because this protection system functions as a safety for electrical equipment from abnormal events or disturbances. In this study ever current relay is used as a protection system, over current relay works based on the current value measured by the PZEM-004T current sensor. The value of the current sensor will be output from the arduino to the relay module, so that the relay will work according to the current limit setting that will be progammed on the UNO arduino as a command to the relay module to break or connect the current in the circuit. The current value and the state of the overcurrent relay will be displayed on the LCD that receives input from the arduino Uno. Very inverse type overcurrent relay (OCR) is one type of OCR that has a longer trip delay time for smaller fault currents and faster at large currents. This allows the system to aperate again faster after a small disturbance. This research aims to design and build dan Arduino-based very inverse type OCR. The system uses PZEM-004T current sensor to detect the current and Arduino Uno microcontroller to process the data and control the relay. The characteristics of the trip delay time of the very inverse type OCR are programmed according to the IEEE C37.122 Standard. With TMS values ranging from 0.01 to 13 seconds. The programme is given setting current value of 2 Amperes and a TMS value of 0.05 seconds. In the test carried out, it was found that the current and trip time were directly proportional to the simulation experiments in ETAP although there was still a slight difference in the tiime difference in current disconnection based on the comparison curve.
