THREE PHASE FAULT ANALYSIS AND LOCATION DETECTOR WITH AUTO RESET ON TEMPORARY FAULT AND PERMANENT TRIP OTHERWISE

Abstract

Abstract: Failure of any phase in a three-phase system will result in a loss in operating voltage, causing either the device to stop working or a three-phase motor to run at lower voltages, reducing speed and increasing vibration. Our technology is not only designed to cure this issue, but also to protect the appliance from further damage. When a phase fails, the load is immediately turned off; if the phase returns before 5 seconds, the load is switched on because the failure was detected as temporary; however, if the time of failure exceeds 5 seconds, it is treated as a permanent failure because it can cause a problem in the load connected, so it is cut off for a long time until the user presses the reset button; only when the user presses the reset button is it turned back on. As a result, in the event of a transient defect, the project's output resets, while in the event of a persistent fault, it obtains a permanent trip condition.The project employs the usual concept of Ohms law, which states that when a low DC voltage is provided at the feeder end via a series resistor (Cable lines), the current will be determined by the location of the cable fault. The voltage across seriesresistors fluctuates as a result of a short circuit (Line to Ground). This is then passed into the Adriano board's built-in ADC, which generates exact digital data for display in kilometers..Keywords - Adriano, Relays, Resistors, permanent fault, temporary, etc.
