Maandusvõrgu

Maandusvõrgu, often translated as grounding grid or earthing grid, refers to a system of interconnected conductors installed underground. Its primary purpose is to provide a low-impedance path for electrical current to dissipate into the earth. This is crucial for safety and operational reliability in various electrical installations.

The construction of a Maandus Võrgu typically involves a network of buried conductors, often made of copper or galvanized steel. These conductors are laid out in a grid pattern, sometimes forming squares or rectangles, and are connected at various points. The size and configuration of the grid depend on factors such as the expected fault currents, soil resistivity, and the specific requirements of the installation.

The main functions of a Maandus Võrgu include protecting personnel and equipment from electric shock by preventing dangerous voltage rises during fault conditions. It also helps to stabilize voltages and improve the performance of electrical systems. In substations and power generation facilities, a robust Maandus Võrgu is essential for dissipating lightning strikes and surges. It plays a vital role in ensuring the safety and integrity of the entire electrical infrastructure.
