Maandusüsteemite

Maandusüsteemite, often translated as grounding systems, are essential electrical safety features. Their primary purpose is to protect both people and equipment from electrical hazards. A grounding system connects the non-current-carrying metal parts of electrical equipment, such as appliance casings and electrical boxes, to the earth. This connection is typically made through a ground wire that runs from the equipment to a grounding electrode buried in the soil.

The key principle behind a grounding system is to provide a low-resistance path for electricity to flow to the ground in the event of a fault. If a live wire accidentally touches the metal casing of an appliance, the casing would become energized. Without a proper grounding system, anyone touching the appliance could receive a dangerous electric shock as current seeks a path to ground through their body. However, with a grounding system in place, the fault current has a much easier path through the ground wire to the earth. This significantly reduces the voltage on the metal casing.

This large fault current will then activate a protective device, such as a circuit breaker or fuse, which will interrupt the flow of electricity, thereby preventing further danger. Grounding systems also help to stabilize voltage levels within an electrical system and can mitigate the effects of lightning strikes by providing a path for the electrical charge to dissipate into the ground. Proper installation and maintenance of grounding systems are critical for their effectiveness.
