1. Introduction – Legislative
The use of modern sophisticated equipment,
consumer electronics and control systems
places high demands on their electromagnetic
compatibility. Modern electronic control
systems provided with circuits with a very high
integration level are becoming more and more
sensitive to electromagnetic disturbance and
overvoltage. The installation of surge protections
according to effective legal standards will
reduce the danger of their being damaged to a
minimum.
Technical designs are defined by standards
harmonised with EU standards:
a) Protective bonding to the same potential
including the conductor cross section for the
main and additional bonding is defined by
standards EN 50310 ed. 2. , IEC 60364-5-54,
IEC 60364-4-41
b) Lightning protection is specified in the
EN 62305 collection of new standards,
harmonised with European standards.
EN 62305 – 1 deals with general principles.

LPL First short discharge
LPL I 200 kA
LPL II 150 kA
LPL III 100 kA
LPL IV 100 kA
IEC/EN 62305 – 2 – deals with the risk
assessment for buildings or engineering
networks struck by lightning.
IEC/EN 62305 – 3 – deals with the proposal
for external lightning protection (lightning
conductor).
IEC/EN 62305 – 4 – deals with protective
measures resulting in the reduction of failures
of electrical and electronic systems inside the
building (zone protection)
c) Classification of protections is set forth in
standard EN 61643-11.
Devices are classified into three basic categories:
SPD type 1 – lightning current arresters
d) Classification of low-voltage distribution
into impulse resistance categories, including
specification of the maximum allowed
overvoltage is determined in standard
EN 60664-1
Protection against lightning and overvoltage
Rated impulse for equipment (acc. to EN 60664-1) or Impulse-withstand voltage.
Lightning protection zones
The standard EN 62305-4 defines lightning
protection zones LPZ in view of the direct and
indirect (electromagnetic pulse – LEMP) lightning
effect:
LPZ 0A – free area (possibility of a direct
lightning strike, non-attenuated LEMP)
LPZ 0B – lightning conductor receiver
protection area (direct lightning strike
protection, non-attenuated LEMP)
LPZ 1 – inside a building (direct lightning strike
is eliminated, attenuated LEMP – depending
upon shielding)
LPZ 2 – inside a room – e.g. a server room with
a conductive floor, FeAl floors and wall lining
(further attenuation of LEMP in connection with
a higher shielding level)
LPZ 3 – inside a metal box (e.g. 19“ RACK)

4. Principle of SPD backing
For the design of an SPD back-up, it is important if we consider the protection priority principle, found in most installations, or the supply priority principle.
Example of an SPD FLP-B+C MAXI V back-up in different supply networks.
The catalogue value of the maximum back-up for FLP-B+C MAXI V is 250 A, for a“V”connection it is 125 A.

5. Principles for positioning and connecting of lightning and surge arresters
Surge protection devices and lightning current arresters cannot be positioned in the distribution board at random. It should be noted that protection
should be located in the closest proximity to the entry feed cable of the distribution board to minimize the area of the induction loop, see the image below.
Examples of SPDs located in a distribution board.
overhead, PEN (PE) at the bottom overhead, PEN (PE) at the top bottom supply, PEN (PE) at the bottom bottom supply, PEN (PE) at the top
Another important condition for connecting the SPD is to minimize the impedance of connecting conductors. Stranded conductors or strip lines are
preferentially used for connecting SPD type 1. It is also important that the length of the connecting conductors is as small as possible – see IEC 60364-5-534
(the total length of connecting conductors must not exceed 1 m). The cross-section of the connecting conductors should be as large as possible – maximum
up to the cross-section according to the type of connector. In SPD type 1 (lightning arresters) the connecting conductors are an integral part of the main
bonding – as determined by the IEC60364-4-41 standard, while minimum cross-sections of the connecting conductors are specified in IEC60364-5-54.
If SPDs are located in circuits where residual current devices are installed, the SPD should be positioned before the residual current device (not in the
residual current device circuit), to prevent spontaneous overload tripping of the RCD affected by surge arresters or lightning current arresters.
Should an overvoltage protection be located in the residual current devices circuit, RCD type S or G should be used. Even in this case it should be noted that
the resistance of these residual current devices is not high (5 to 8 kA in wave 8/20 μs) which makes it impossible to use any SPD in the circuit of the residual
current device. If you want to prevent a residual current device type S or G responding to surge protection by overload tripping, only a protection SPD type
3 can be used in the circuit of the residual current device.
Example of SPD FLP-12,5 V back-up in different supply networks.
The catalogue value of the maximum back-up for FLP-12,5 V is F2 =160 A.

6. SPD dimensioning
Dimensioning is only provided for SPD type 1. The basis for that is the calculation of the lightning protection level (LPL) for the down conductor (LPS).
The table below is taken from CLC/TS 61643-12 and shows the minimum value of the current withstand per pole according to the lightning protection level
(LPL) structure classification.

7. Reducing overvoltage using LPZ zones
The principle of reducing overvoltage using zones lies in the progressive reduction of the overvoltage level to a safe value that will not damage
the specific equipment or technology. To obtain a safe overvoltage value, the whole structure is divided into individual zones and an SPD is installed
at the boundary between the zones..

Examples of SPD applications
Modern family houses feature more and more electronic equipment. If the owner of the structure wants to watch TV, be in contact with the world via the
Internet, control the heating in the structure automatically, use various electronic equipment without any trouble, it is necessary to protect such equipment
against atmospheric events. Lightning strikes hitting the structure or near the structure and overvoltage in the mains can destroy or damage such electronic
devices or otherwise make use of such sensitive appliances uncomfortable.
Internal protection against lightning and overvoltage must be considered as an integrated system. For most family houses it is OK to install SPD type 1 and
2 at the line entry in the structure (the main distribution board where the circuit breakers for the whole house are located), i.e. FLP-B+C MAXI V(S)/3 for the
wiring connected in TN-C or TN-C-S, or FLP-B+C MAXI V(S)/4 for the wiring in the TN-S network. For sensitive appliances inside the structure, it is sufficient to
use overvoltage protection - SPD type 3, in combination with respective data protection.
It should further be noted that antenna down conductors at the structure entry must also be considered. For such cases, we use the FX-090 F75 T current
arrester.
If the structure has ESS, EPS, or electronics to control the heating system, overvoltage protection SPD type 3 with vf filter type DA-275 DF 6 will be used to
protect the supply 230 V AC, which will be installed in close proximity to the protected equipment.
If the structure has photovoltaic panels installed on the roof, you need to protect the panels as well as the DC/AC inverter. Protection for photovoltaic
equipment, e.g. the SLP-PV500 V/U type, is used to protect the DC part.
The following examples show various options for connecting the structure to the distribution network.
