Re: [time-nuts] Transformer inrush current and transformer simulation

Don't let the start of the simulation be the power on time. Best to set up the AC mains volts at zero volts for a half second then go up to 120 VAC. So you actually simulate the power switch. The time before the start of the run is not defined Also you should Google "spice transformer model"
