lackisolierter
lackisolierter is a German term that literally translates to “paint‑insulated.” It refers to a condition in which a metallic component that is normally grounded or insulated is covered in paint or varnish that has become a conductive medium, thus compromising the intended electrical isolation. The phenomenon is typically observed in older electrical and electronic equipment where paint was applied for aesthetic or protective reasons but inadvertently formed a continuous path of conductivity between live parts.
The origin of lackisolierter is traced back to the early 20th century, particularly in electro‑mechanical devices
In contemporary engineering texts, lackisolierter is cited as a classic example of dielectric failure. It is
