Actually my first post was incomplete, this is the calculations for
resonant cap for 12kV-at-60mA NST
22/10/2544 14:52:13
NST Voltage Rating 12000
Transformer Current Rating 60 mA
Firing Voltage 16970.52
Desired capacitance value 13.2629 nF (Resonant)
Strings Caps/String Cap Voltage Temp C V Rating T
Rating Life expectancy
2 15 13.3 24,000 3.82 Good
Excellent 45750.85 weeks
