Chapter The internal lightning protection system
.
In addition, systems, surge protection for in-
formation and communication technology recom-
mended. To
prevent loss investments, relevant insurance-related
questions need considered.2.2.
Using surge protection devices reduces downtimes of
devices and systems. Surge
protection measures should taken for the following
devices and systems:
Antenna systems
• Cable connection
• Antennas
• E. TVs, videos and DVD recorders, stereos
Telephone systems
• Analogue
• ISDN NTBA
• telephony systems
Construction engineering/installations
• Heating controls
• Solar and photovoltaic systems
• Building automation
Terminals
• Computer
• Household appliances, burglar alarm systems, etc.
If new system connected electrical sys-
tem, surge protection (type the side re-
quired according IEC 60364-4-44 and 60364-7-
712. Only protected
system can withstand these loads and reliably pro-
duce electricity.3 Residential and industrial applications
Transient surges resulting from lightning strikes and
switching operations cause the failure and destruction
of electronic devices.4. The German Supplementary Sheet the light-
ning protection standard IEC 62305-3 also requires –
to protect the inverter the installation surge pro-
tection the side.4 systems
Surge voltages can lead the failure systems
and hence failure achieve the expected yields.
