Weighbridge Lightning Protection is vital due to the fact that weighbridges technology is vulnerable to lightning strikes, the consequences of which can be very expensive to repair, not to mention the knock-on effects of the weighbridge being out of order.
There are various types of lightning strike, but the one that concerns us is the dramatic forked lightning. A weighbridge, by nature, is very unlikely to be the tallest structure in its locality and so will rarely be directly struck by lightning. If it does receive a direct hit then no weighbridge in the world could withstand the electrical energy that would strike it and then pass through its load cells as the easiest route to earth.
CWCSA approach the problem of lightning protection from the point of view of preventing damage from this dissipated energy.
Protection is provided by,
- Inductive lightning protection within each load-cell,
- Copper straps connecting the platform steel structure to the base plates, thus bypassing each load-cell,
- Copper cables connecting each platform to an earthed spike and the instrumentation to one of the earthed spikes.
- A Data protection device will be provided and installed.
- A Surge protection device will be provided but not installed; the customers appointed electrician must do this into the Distribution Board.
