  • Engineers must account for corona discharges to prevent energy loss in electrical systems.

Examples

  • The sparks are moving all around the wire and this now the stringers are starting to go away and it's just turning into kind of a corona glow.

  • With the help of this microphone we can hear this corona discharge as it starts as the voltage is raised.

  • I'm still losing a lot of charge due to corona discharge.

  • Higher voltages create corona discharges into the surrounding environment, causing power loss and possible cable and system damage.

Etymology

Corona comes from the Latin corona, meaning 'crown', because the faint glow around a high-voltage wire looks like a glowing 'crown'. So, engineers call that ring of light a corona.
