Tracking resistance

Tracking is a phenomenon in which dust or moisture adheres between electrically insulated (electrically isolated) conductors, causing a short circuit that can lead to ignition or dielectric breakdown due to a large short-circuit current. A common example is when dust accumulated in an electrical outlet causes a short circuit and develops into an electrical fire. The term refers to resistance to this type of tracking. To improve tracking resistance, methods include adopting a structure that prevents dust accumulation, using materials that are less likely to generate static electricity, and implementing a waterproof structure.
