maandussüsteemi

Maandussüsteemi, often translated as "grounding system" or "earthing system," refers to the practice of intentionally connecting electrical equipment and systems to the Earth. This connection serves a critical safety function by providing a low-resistance path for fault currents to flow to the ground, rather than through people or sensitive components. Without a proper maandussüsteemi, a fault that causes a live wire to touch the metal casing of an appliance could energize that casing, posing a severe shock hazard to anyone who touches it.

The primary purpose of a maandussüsteemi is to protect against electric shock and to prevent damage to electrical and electronic equipment. It also plays a role in stabilizing voltage levels within the electrical system and can help to dissipate static electricity and protect against lightning strikes. In a typical residential or industrial setting, the maandussüsteemi involves a grounding electrode, usually a rod driven into the earth, connected to the main electrical panel by a grounding conductor. All accessible metal parts of electrical equipment are then bonded to this grounding system.

The effectiveness of a maandussüsteemi is dependent on the resistance of the earth connection. Lower resistance ensures that fault currents can be safely diverted. Regulations and standards, such as those found in electrical codes, dictate the specific requirements for installing and maintaining grounding systems to ensure their reliability and safety. Regular testing and inspection are often recommended to verify the integrity of the maandussüsteemi.
