how to kill ac inductive load spiking is there a fast n dirty way to kill the line spiking that occurs when an inductive load is turned on sometime other than at zero crossing of the ac cycle a capacitor kludged in somehow etc i ve got a microcontroller that is running a bunch of valves and pumps in a big instrument washer and almost everything is being switched with zero crossing solid state relays so that stuff stays quiet ac wise but there s one steam valve that gets turned on by a mechanical relay in the water tank fill thermostat system and it s not under control of my ssrs and it does sometimes generate radiate a spike that resets one of my peripheral chips my software times out and tries again but i d love to just tack in a magic spike killing fix that would avoid having to do some major rewiring redesign a varistor would help but might not be sufficient ideas paul marxhausen university of nebraska lincoln grace happens
