Characterization of arc for domestic electrical system

Undesired arcing in domestic electrical system can be caused by worn or broken insulator, loose connections, or static electricity. The arc heat energy is a fire hazard. In electrical equipment, an arc with enough energy can melt insulator or even cause fire. The present protection system in Malaysi...
