DC spark-over voltage V
This value is determined by applying
a dc voltage with a low rate of rise
dv/dt = 100 V/s (Fig. 17).
Nominal dc spark-over voltage
V
This is a rated value used to desig-
nate a surge arrester. The operating
characteristics and tolerances as well
as limit and test values are referred
to V
values of the dc spark-over voltage,
which are subject to statistical
variations due to the physical
phenomena of gas discharge.
Tolerance of V
The tolerance is generally specified
as a percentage of V
specifications take into account
individual and batch variations in
arrester production.

Impulse spark-over voltage v
The impulse spark-over voltage
characterizes the dynamic behavior
of a surge arrester. The values
specified in the product part refer to a
voltage rise rate of dv/dt = 100 V/µs
and 1 kV/µs (Fig. 17).Complete v
distribution data is available upon
request.

Requirements of ITU-T and DIN VDE:
10 discharges at intervals of:
ITU-T: no accumulation of the DUT
temperature.
DIN VDE: 1 min
Nominal alternating discharge
current I
Rated rms value of an ac current

Requirements of:
ITU-T: 10 discharges (no accumula-
tion of the DUT temperature).

Maximum single-impulse
discharge current

wave (Fig. 18).
AC discharge current
RMS value of ac current for 9 cycles
at 50 Hz (in accordance with RUS
PE-80 11 cycles at 60 Hz).
Maximum follow-on current
For the type series L71-… we specify
this performance feature as the
maximum permissible current which
may flow from the supply current
source through the arrester in the
interval between the decay of
the surge and the following zero
crossing of the ac voltage. This
discharge may be repeated ten
times during an interval of 30 s.
