Abstract
Explosion-proof electrical equipment must be tested with the spark test apparatus (STA). This discharge was important for electrical explosion-proof safety. This study aimed to investigate the effect of field emission on the contact spark of the STA. Results show that the primary discharge modes were field emission and electron impact ionization. The gap width was estimated to be 6–8 μm. The distribution of the ions and radicals were revealed under the different field emissions. The impact of radicals on ignition was also discussed.
