External Protection

The main purpose of a LPS (Lightning protection system) is to provide security at an structure against lightning damage and physical injury to living beings due to touch voltages and step voltages

 

The main missions of a LPS (Lightning protection system) external type are:
1. Atmospheric intercept a direct download on the structure.
2. Lead current safely to ground.
3. Disperse the discharge current in the ground.

 

According to the types of devices, external protection can be:
1 .- EXTERNAL ACTIVE PROTECTION

It is offered by collectors with primer (ESE), which emit a stream of ions directed into the clouds (tracer).

The positive electrical charge of these ions attracts the rays (negative charge), which increases the probability that the discharge is occurring on the sensor.


SPCR_ACTIVA

2 .- EXTERNAL PASSIVE PROTECTION

It is offered systems (type 'Faraday cage') that have no effect for the abstraction of the ray (preventive action). These systems may use elements of the structure to protect the discharge of current to earth.

SPCR_PASIVA

3 .- EXTERNAL MIXED PROTECTION

External protection systems can be combined active and passive, and must be chosen according to the characteristics of the building to be protected.

It is offered by collectors with primer (ESE), which emit a stream of ions directed into the clouds (tracer).

The positive electrical charge of these ions attracts the rays (negative charge), which increases the probability that the discharge is occurring on the sensor.
