i have a circuit containing an inductor,a coil of insulated copper wire of 664 turns.The source voltage is 50 vdc and the coil has a resistance of 0.7 ohms.The coil is energised and de energised by a split ring,carbon brush swithc arrangement.I find there is heavy arcing at the switch especially when the switch is opening.One expected this from an inductive circuit.However,the puzzle is that i have applied all the techniques to quench the arcing,or at least reduce it considerably but to no avail.
I have used the quencharc,the metal oxide varistor,the capacitor-resistor arrangement etc.
Nothing seems to be working.I will be extremely grateful if any member can assist me to quench this arc which is ruining the switch all the time.
