Re: "I would suggest that you should calculate the capacitive reactance of your .0085 mfd cap--I get about 312K ohms at 60 Hz. Not sure if you use 50 or 60 Hz power, but the point is that would result in a current draw of 48 milliamps on your 15,000 volt transformer and it is rated at 30 milliamps, per your comments above. " NEGATIVE!!! Since the transformer reactance is positive and the capacitor reactance is negative, the effective reactance will be 500,000 - 312,000 or 188,000 and the available current is 15000/188000 or about 80 mils, which could raise the terminal voltage to well over 20 kV rms!! Will work fine, if gap length is kept within safe values. Ed Phillips
