DESIGN OF AN ARDUINO BASED RFID LINE SWITCHING USING SOLID STATE RELAY WITH INDIVIDUAL PHASE SELECTION

Abstract

The use of line switching in the power system cannot be over emphasized. When fault is detected on a distribution line, the line is disconnected/isolated due to the presence of this fault and switched over to another distribution line by a line switching system. In this paper, a simple and reliable line switching system for distribution lines is presented so as to achieve the basic objectives of power system protection which are continuity of power supply and safety of personnel and equipment. The design includes the utilization of numerous modules/units such as the radio frequency module (RF module), a microcontroller, and a Radio Frequency Identifier (RFID) reader. The RFID card is swiped across the sensor and the experimental result shows the phase selected and the output of phase(s) available upon selection.
