When lightning strikes, a phenomenon called ' corona discharge ', in which small blue sparks are generated from the tips of plants growing around the impact point, may be confirmed. A research team at ...

The phenomenon of corona discharge involves the ionisation of air surrounding high-voltage conductors, leading to energy losses and the generation of audible noise. This process is highly sensitive to ...

MIT scientists have found that wind enhances St. Elmo's Fire on the ground, but tames it in the air. The "corona discharge" skims harmlessly over airplanes, trees, and tall buildings. A controlled ...

The electrical phenomenon known as St. Elmo’s fire manifests during strong thunderstorms as a flash of blue light, usually at the tips of electrically conductive structures like cell phone towers, ...

THE form of the d.c. corona discharge in air differs according to the polarity of the electrode near which it occurs. In an electrode system comprising a wire and a coaxially mounted ring, the ...

Research conducted by the Electric Power Research Institute (EPRI) has confirmed that corona discharges can degrade certain 115-kV and 138 kV polymer transmission line insulators and that it has ...

New research examines the removal of harmful organic substances, such as pharmaceutical residues, energy efficiently from wastewater using only electricity. According to practical tests, pulsed corona ...

A sharp conductor on the Van de Graaff generator will emit electrons via corona discharge and prevent arcing to an adjacent grounded tower. A shard of GaAs on a Van de Graaff generator will also ...
