päämaadoituksessa
Päämaadoitus refers to the main grounding connection within an electrical system. It is a critical safety measure designed to protect both people and equipment from electrical hazards. The primary function of päämaadoitus is to provide a low-resistance path for fault current to flow to the earth. This prevents dangerous voltages from accumulating on conductive surfaces that are not normally energized, such as metal casings of appliances or electrical enclosures.
In a properly grounded system, if a live wire accidentally touches a metal part, the fault current
The concept of päämaadoitus is fundamental in electrical installations, especially in buildings and industrial settings. It
