Metal Oxide Surge Arresters (MOSAs) are critical electrical devices used in power systems to protect sensitive equipment and installations from surges or transient voltage spikes. These arresters are widely used in substations, power plants, and industrial facilities, as well as in commercial and residential electrical installations. They help safeguard electrical infrastructure by diverting excess voltage to the ground, thus preventing damage to transformers, switchgear, and other components from lightning strikes, switching surges, or other transient electrical disturbances.

Metal Oxide Surge Arrester

Metal Oxide Surge Arresters are widely preferred due to their superior performance compared to traditional silicon carbide surge arresters. MOSAs are designed to provide high energy absorption, low residual voltage, and excellent protection against voltage surges. These arresters are based on zinc oxide (ZnO) varistors, which have a non-linear voltage-current characteristic, making them highly effective at clamping overvoltage conditions.

The primary advantage of MOSAs is their ability to operate at high efficiency, with lower energy losses and longer service life. They are designed to handle both fast transients and slower, prolonged surges, making them highly effective for a range of surge protection applications. MOSAs are also more compact and require less maintenance compared to traditional arresters, which makes them an attractive option for many industries.

In addition to their use in power systems, MOSAs are also used in telecommunication networks, railway systems, and renewable energy systems like wind and solar farms. The high reliability of MOSAs, combined with their ability to protect delicate electronic components, makes them a key element in preventing costly equipment damage.
