This document provides information on Aplicaciones Tecnologicas's lightning protection systems and products. It discusses [1] the need for lightning protection on structures, [2] how lightning is formed, [3] the destructive effects of lightning, [4] how to assess lightning risk, [5] international standards for lightning protection, and [6] guidelines for designing a system using early streamer emission air terminals. The company offers complete lightning protection solutions including interception systems, downconductors, earthing components, and exothermic welding.
There are many advantages of using exothermic welding. The most important one being that the process produces a molecular joint and not just a mechanical one in between the conductors.
In this way, Apliweld® guarantees all types of common joints, not only copper cable unions but also to weld tapes, brass metallic pieces, stainless steel, steel ground rods covered with copper, etc…
Overvoltages are an increase of voltage on the electric line, measure between two conductors, which can produce damage on the installations
and the electric equipments.
There are two different types: transient and permanent.
Permanent or power frequency overvoltages are characterized by relatively long duration (several cycles) There are usually caused by:
- Defect connection of the neutral.
- Power consumption lowered.
Transient overvoltages are very short duration increases in voltage
between two conductors or between a conductor and the ground. They
can be on account of atmospheric electrical discharges (lightning), by
switching or by electrical faults (contact with earth or short circuit).

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

4. IMPORTANCE OF A SUITABLE EARTHING
A well designed earthing system is basic for any electrical installation to avoid the
danger associated with fault currents, as established in the main earthing standards:
Spain: RBT2002 “Low Voltage Electrotechnical Regulation”. ITC-18 “Earthing
systems”.
Great Britain: BS 7430 “Code of practice for Earthing”.
France: NF C 15-100 “Low Voltage Electrical Installations”.
Germany: DIN VDE 0100 Part 540 “Earthing arrangements, protective
conductors, equipotential bonding conductors”
USA: UL 467 “Grounding and bonding equipment”.
A Low Voltage Earth Termination System
is aimed:
To provide security for persons
by limiting the touch voltage.
To protect installations and equipment
by providing a low impedance path.
To improve the quality of the signal
by minimizing the electromagnetic noise.
To fix a reference voltage for the
system equipotentialization.
A low Earth Resistance is essential for obtaining an efficient Earthing. Conductors
with an accurate section should be used in order to carry the expected current.
Besides, they must be durable against corrosion.
The value of the electrical resistance must be measured at the Lightning
Protection Earthing, isolated from any other conductive element. Therefore, it is
necessary to use disconnectors in order to separate the Earthing from the rest of
the installation during the measurements.
Other determining factors for designing the
Earth Termination System are the following:
The resistance should be measured regularly
so it is necessary to place an inspection pit.
The soil humidity will reduce the earthing resistance.
Earthing enhancing compounds
reduce the soil resistivity.
Buried electricity and gas installations
should be known in order to respect the
security distances for each case.
Buried pipes and water tanks should be
known in order to bond them equipotentially
with the earth termination.
In low-conductivity soils, enhanced electrodes, deep electrodes or ring
conductors should be used in order to obtain a suitable earth resistance.
252 EARTHING
5. SPECIFIC CONSIDERATIONS FOR LIGHTNING PROTECTION
Particularly, the Earth Termination System is essential for Lightning Protection,
since the lightning current should disperse there. Each down-conductor must
have an Earth Termination System, formed by conductive elements in contact
with the soil and able to disperse the lightning current in it.
Good earthings of Lightning Protection Systems shall be able
to withstand lightning currents and to disperse them quick and
safely.
In order to accomplish with these requirements, standards set as a first
specification that the resistance of the LPS earthing should be lower than 10Ω.
On another side, it should be noticed that lightning current is an impulse and
therefore it is not advisable to use a single, very long element. The employ of
deep electrodes is interesting if the resistivity is very high at surface but there are
lower layers with much more humidity. Configurations in triangle or “goose-foot”
are suitable for a good lightning current dispersion.
These considerations for improving the impedance should be taken into account
when the earthing is made, since normally the measures are made afterwards
with a conventional Earth Meter which does not register the impedance but
only the earthing resistance, that is, its performance in case the current were
continuous. A high inductance would not be measured by this type of Earth
Meters and however it is a big obstacle for the current flowing when its waveshape
is, such as lightning, an impulse.
In general it is recommended to bond the Lightning Protection Earth System
with the earthings of the installation in order to avoid surges and dangerous step
voltages.

GROUND ENHANCING PRODUCTS
CONDUCTIVER PLUS is a non corrosive ground enhancing gel with low solubility but is very hygroscopic. It is made of an electrolyte base, which
contributes to the conductivity of the mixture.
The conductivity of the ground is almost exclusively of an electrolytic nature due to the salts dispersed in the water which impregnate it and which concentrate
on the surface due to an adhesive phenomenon of the sand grains and clay in the ground.
Therefore, it is possible to increase the conductivity of the ground, improving its absorption power, retention of water and increasing its richness in soluble salts.
It would be very easy to achieve this effect using a simple method, impregnating it with any electrolyte, such as common salt (NaCl) or sodium carbonate
(Na2CO3), but the high solubility of these salts, as well as their low absorption in the ground mean that they are very quickly swept away by the infiltration waters,
making their action very short term. Another inconvenience of common salt is its corrosive effects on the earthing electrodes.
The components of the CONDUCTIVER PLUS ® gel have been selected according to their solubility, in order to obtain from the soluble components, a low
soluble product, which will provide us with a long lasting conductor product deposit. The main advantage of this product is that a conductor gel is formed
below the soil near the electrode.
In summary, the CONDUCTIVER PLUS® gel is characterised by:
Having the capacity to create partially ionized electrolytes, with a high charge and a high capacity to retain water and to form gels.
Remaining in the ground for a long time, thanks to the formation of links with the particles.
Increasing conductivity (approximately 200%) of the ground during one year and rainfall of 700 litres/m2.
Not causing corrosion of the earth electrodes.
Being totally ecological.
METHOD OF APPLICATION
1. The ground can be dry, no previous preparation is necessary.
2. Prepare a mixture of the YELLOW product in 5 litres of water using the measuring recipient.
3. Empty the first solution to the ground and add another 5 litres of water.
4. Leave the product to disappear into the ground.
5. Clean the recipient before continuing with the next product.
6. Prepare a second solution with the WHITE product and 5 litres of water. Empty this mixture evenly on the ground. Add another 5 litres of water. Leave to
filter until complete absorption.
7. Once the second product has filtered, you can then take the earth resistance measurement.
