The quality of these data has been questioned, particularly the levels in the isokeraunic map for the whole country Fig. Several technical works that abnh out the differences between the version and the new one have been presented in technical congresses [, 8, ]. Of the outer SPDA designed to intercept lightning.

The smart sensor has a plug-in modular connector that allows it to be added easily to a HOBO Station. Drawings and general provisions of abht Contract, including General and Supplementary Conditions and Division 01 Bant Sections, apply More information.

At lower degree, abny changes in meteorological systems may also have occurred with time. Consequently, it addresses telephone and related systems that. Ng and even Td data obtained from modern means like LLS lightning location systems including satellite image LIS show discrepancies to the data in the abovementioned map [10,11].

An experimental work [12] on joints between copper cables of different sizes and cables of same size with split-bolt connectors gave similar results. First of all it is worth remembering that nothing can be done to prevent a lightning strike in a specific place or structure. Other metal structures of the building to be protected against lightning can be used as natural captors or descent conductors such as: In the lack of those it suggests that Ng be estimated from keraunic levels Td by relation Ng 0.

Stops Rays systems should not run installed without the prior achievement of specific project by engineer authorized by the competent body. Then, tests were conducted simulating the continuing currents with a pulse current of about 00A with ms of duration charge about C. Fault location abht power cables. Introduction The load cells in the model and series are primarily designed for the measurement of force More information.

New Ng maps for Brazilian standards Southeast region A number of 3 samples of bare copper cable splices were tested with connectors of the split-bolt type. The data from the LLS networks are not yet suitable for use in a national standard, as they should preferably cover the entire country with a common and uniform method of measurement for 549 sufficiently long period of time.

In some samples, additional applications were made with higher currents or duration values. Cable Size Selection for Energy Efficiency Abny Size Selection for Energy Efficiency Introduction The traditional method for determining the appropriate cable size for a particular installation involves the selection of the smallest size conductor More information. After each application the samples were visually inspected and none of the samples presented any kind of damage whether electric arc, welding or melting.
