Chapter The internal lightning protection system
.32 specifies: "Surge protection devices must
meet IEC 61643.
(Source: Luminaires 60598-1)
Installation location Description Protection device Item no."
If there direct lightning strike the mast lumin-
aire, large portion the lightning current will flow
directly into the earth, creating potential difference to
the supply cable.
The luminaire standard "Fpr 60598-1: 2012-11 Lu-
minaires Part General Requirements and Tests",
Point 4.
According the testing standard, each protection
device must have thermal monitoring and must be
isolated safely there defect. Powerful lightning current combin-
ation arrestors can arrest the energy-rich currents.
Surge protection devices must
correspond IEC 61643
