>standards

Implementing rules for an effective person and property protection system:

-  UNE21186:2011:Lightning protection - Lightning rods with priming device.

-  NF C 17-102:2011:Early streamer emission lightning protection systems.

 - NP 4426:2013:Lightning protection - systems with non-radioactive ionization device.

In addition to these,there may be legislation or rules of each country or rules of each country that must be taken into account.

> risk index calculation

Annex A(risk analysis) of the UNE 21186:2011 determines the need or not to install external lightning protection and the level of protection applied to reduce the risk of damage caused by lightning.

> protection radius calculation

Lightning rods with an early streamer emission priming device(ESE),have a protection radius depending on the necessaary protective level to be obtained by performing tests in accordance with UNE 21186:2011 or NF C 17102: 2011,and must be certified by an accredited high voltage laboratory.

Table 1-Early Streamer AT(ms)RY

ESE lightning rods

UNE2118:2011(paragraph C.2.2) indicates that a ESE lightning rod must obtain an early streamer emission

AT＞10ms minimum.

Also,the maximum permissible value is 60ms although tests were obtained with superior results.

The area to be protected by a ESE arrester is delimited by a surface of revolution that is defined by the radius

Of the corresponding protection to different heights(h)considered,whose axis is the same ESE arrester.

►example radius protection calculation Rp(model REAZY RY-PDC 3.1):

To calculate the different radius of protection of a ESE lightning rod,we must know the variables involved in the

Formulation:

﹒REAZY PDC3.1 model has AT=15 ms and thus A=15 m.

﹒Apply level Ⅱprotection,the notional sphere radius corresponds to r=30m.

﹒Consider the height h=20m.

Each Rpn radu are calculated,for each reference point,using the formula:

For the given model the radu are shown in table 3:

The total volume of protection can be represented graphically(See Pig.3).

Once each radius is calculated Rp,verify that the building remains within the lightning rod protection radius(see pig.4).
