Equipotential bonding in lightning protection is an essential measure of internal lightning protection to equalise differences in potential between the lightning currents outside and the energy and IT supply systems inside the building.
While our experts connect passive elements such as metal pipes and cable shields directly to the equipotential bonding, they implement surge protection devices for the sensitive electronic operating systems within the building at the transition from outside to inside in order to reduce the energetic disturbances to a tolerable level.
Our experienced engineering and installation specialists also consistently include the information technology cables brought in from outside in the potential equalisation with surge protection. For their protective circuit, we determine a suitable combination of surge-limiting components that adequately protect the information technology systems. Technical parameters such as the maximum operating voltage, the maximum possible operating current and the signal frequency of the IT system form part of the special requirements that our expert planners take into account in their calculations.
Within thunderstorm cells there are areas with positive and negative charges. If the voltage differences are too great, an electrical discharge occurs. It is not only the direct impact that has consequences.
Structural installations and electrical systems are nevertheless at high risk due to the electromagnetic pulse fields emitted by lightning currents. These generate surges of several thousand volts through induction, which can trigger fires and explosions or attack electrical and electronic supply systems in the surrounding area – with enormous immaterial and material consequences. Professionally planned and installed surge protection provides a remedy.
