suojamaadoitusjärjestelyt
Suojamaadoitusjärjestelyt refer to the grounding arrangements designed to ensure safety in electrical installations. The primary purpose of a protective earth system is to prevent electric shock by ensuring that exposed conductive parts of electrical equipment are connected to the earth electrode. This connection provides a low-impedance path for fault current to flow to the ground, thereby activating protective devices like circuit breakers or fuses.
In a typical suojamaadoitusjärjestely, a protective conductor (PE) connects the metallic casing of electrical appliances and
Different earthing systems exist, such as TN, TT, and IT systems, each with specific configurations of power
