hi could someone please explain the attached circuit to me in detail. From what i understand: the open circuit caused by the opened switch in series with the resistance causes a fault current in the system. This higher than normal current across the 200 ohm resistor causes a high voltage to flow through the mosfet and into the inverting input. the input is then compared to a reference( using a schmitt trigger config Threshold values set to 1 an 5V. ) when input increases past the high threshold value set the output is low, when input is below high threshold output is high. The low output will turn the mosfet off and the high output will turn it on. When the mosfet turns on, a voltage is sent to the switch closing the switch. This switch should not close until the fault current is cleared and the switch doesnt re-open unless reset. based on what i explain is my design correct. Think of what i am doing as a way to clear a fault current using a schmitt trigger configuration+ a mosfet+ a mechnical switch please help.
