Exploding Capacitor (Show and Tell ONLY!) (5C30.20)
/Exploding_Capacitor_(5C30.20).jpg)
Three 1500 mF capacitors are connected in parallel and charged to 400 volts. A discharge bar shows the stored energy could melt and vaporize metals. This configuration is no longer used or charged due to safety concerns.
None. Show the capacitor bank and discharge bar to the class.
Warning: Most electrolytic capacitors are not rated for pulse discharge applications. They have a higher Equivalent Series Resistance (ESR) or Inductance (ESL) and can explode under high current pulses.
