    hello guys i really need ur help in making circuit that can sense the current fault using the di/dt technique and then it indicate the fault by turning on led then i use timer to reset back the led off if the current returned back to its value plz help me guys

    That is hard to understand. Do you mean to detect a lamp failure by monitoring current? Or is this to detect a short circuit?

    What is the "overhead transmission line" carrying? Is it a signal or does it transmit high voltage power?
