Surge Arrestors

Strong electromagnetic fields and discharge currents generated by lightning strikes cause significant damages to the civil and industrial buildings, electrical grids and power network equipment connected to grid. Effects of the electromagnetic fields remain significant at very large distances (10 km) from the place of lightning strike, each thunder storm activate protections and quits running a large number of medium voltage lines and receivers.

Protection against atmospheric and transient overvoltage is made using specially designed equipment (spark gaps, gas tube dischargers, varistors, limiting diodes) that are mounted at the entrance of the main and distribution switchboards, distribution panels, plugs, coaxial and data cables.
