Creating an Electrical Wire Corona: Voltage, Amps & Cameras

Click For Summary
SUMMARY

To create a corona around an electrical wire, a voltage of at least 10,000 volts is typically required, with the current depending on the wire's material and diameter. Common materials include copper and aluminum, which influence the corona discharge characteristics. High-speed cameras, such as the Phantom series, are recommended for capturing the phenomenon due to their ability to record at high frame rates. This process is crucial for visualizing electrical discharges and understanding their behavior in various applications.

PREREQUISITES
  • Understanding of electrical principles, specifically corona discharge.
  • Familiarity with wire materials, particularly copper and aluminum.
  • Knowledge of high-voltage safety protocols.
  • Experience with high-speed photography techniques.
NEXT STEPS
  • Research the properties of corona discharge in different materials.
  • Explore high-speed camera options, focusing on the Phantom series.
  • Investigate safety measures for working with high-voltage electricity.
  • Learn about the effects of wire diameter on corona formation.
USEFUL FOR

Electrical engineers, physicists, photographers interested in high-speed imaging, and hobbyists experimenting with electrical phenomena.

Does anyone know what current voltage, amps would be required
to produce a corona around an electrical wire? I gather that this
would also be dependent upon the wire material and size. I have
seen photos of this and would like to do reproduce the process.
What type of camera may these have be filmed with??
