High Voltage Glossary

The High Voltage glossary at provides definitions for
such terms as corona, dielectric withstanding voltage and creepage
distance. Other terms with particular meanings for high voltage
applications include:

FLASHOVER (A disruptive discharge of electricity through an
insulator, normally characterized by a voltage drop. Also, a
discharge around or over a liquid or solid material. This can be a
single event, intermittent or continuous. Same as Arc)

TRACKING (Marks made on a surface that experienced flashover)

CORONA INCEPTION VOLTAGE: The lowest voltage at which continuous
corona of specified pulse amplitude occurs as the applied voltage is
gradually increased.
