Three Phase Fault Analysis with Auto Reset on Temporary Fault and Permanent Trip

Phase Failure in three phase systems are quite common faults experienced by three phase devices, failure of any phase will cause drop in operating voltage which will cause either device to stop working or three phase motor to run at lower voltages thus reducing the speed and increasing vibration due to it. Our system is designed to solve this problem and hence saving the appliance from damage. Using combination of timer ICs we measure the time, when the phase fails then the load is turned off immediately, if the phase returns before 8-10seconds then the load is switched on since the failure is detected as temporary, but if the time of failure exceeds 8-10 seconds then it is treated as permanent failure as it can cause a problem in the load connected so this time it is switched off permanently, only when the user presses the reset button again the system restarts. Hence, in case of a temporary fault the output of the project resets and in case of permanent fault it acquires permanent trip condition. This three-phase fault analysis system automatically differentiates between a temporary disturbance and a permanent fault and appropriately cuts the supply for a short duration or long duration respectively.
