Re: Bleeder Resistors

Bleeder resistors are used to drain remaining charge from the capacitors in the tank circuit. If the remaining voltage after shutdown of the NST is too low to make the spark gap fire, the cap will not discharge into the primary and will hold a potentially lethal charge. A bleeder resistor across every single capacitor in the MMC will consume this charge turning it into heat which is better than having several kilovolts across the capacitors being available to shock you if you make adjustments to your system without shorting out every single cap. Furthermore a capacitor can regain charge from dielectric memory. The resulting voltage can exceed several hundreds of volts since there are so many capacitors in series in an MMC.

Bleeder resistor is not necessary unless you are running DC on this cap.

I am using a .03 uF / 35,000 v Maxwell capacitor on a 15/60 NST powered static gap coil. Can a bleeder resistor be used on this type of cap? If so, what type of resistor is needed? I'd appreciate specs, brand, part number. Thanks. Dennis Hopkinton, MA
