We have discussed about the internal arc fault in switchgears which has the most severe effects in the power systems and is directly related to the safety of the operators and the installed base of the equipment.

Discussion includes the reasons causing the generation of an internal arc fault within the switchgears, the effects of an arc flash on the surrounding environment. In the last part of the video discussion is on the internal arc classification for switchgear under IEC 62271-200.
