maajohtimed
Maajohtimet are electrical conductors designed to connect electrical systems to the earth. Their primary function is to provide a low-resistance path for fault currents to flow to the ground, thereby preventing dangerous voltage buildup on conductive surfaces. This is crucial for electrical safety, as it helps to protect people from electric shock and reduces the risk of fire caused by electrical faults.
In a typical electrical installation, maajohtimet are part of the earthing system. This system usually consists
The effectiveness of a maajohdin relies on a robust connection to the earth itself. This is achieved
