The smart sensor has a plug-in modular connector that allows it to be added easily to a HOBO Station. A mass M is attached to the end of a horizontal. It worth mentioning that the current standard defines minimum sizes of 35 mm 2 for copper conductors on airtermination system and 35 mm 2 or 1 mm 2 for downconductors, depending on structure height.

Its data accumulated along the last 1 years are coherent with ground flash distributions obtained by LLS networks in Southeast region and with the more detailed map of isokeraunic levels given in the current NBR 51 Fig.

The standard should offer a solution for all cases anyhow. In the lack of those it suggests that Ng be estimated from keraunic levels Td by relation Ng 0. Initially, the electrical contact resistances of all samples were agnt before current applications. Sinceone More information.
