Testing an SPD module with RFID system (LifeCheck)
Regular testing of installed SPDs
Multiple discharges with values beyond the specification of the device
affected can overload surge arresters in telecommunications and signalling
networks. To ensure a high system reliability, it is therefore recommendable
to subject SPDs to systematic tests.
IEC 62305-3 Ed. 1.0 [see Table] defines maintenance tests and test intervals
for lightning protection systems. The maintenance programme should
include the testing of SPDs designed for lightning equipotential bonding:
Protection level Complete inspection Visual inspection
I and II 2 years 1 year
III, IV 4 years 2 years
This table shall be considered generally a recommendation for lightning
protection systems. For individual cases, however, these values can differ
from the requirements of critical systems and specific directives (e.g.
Regulations of the Nuclear Power Committee (KTA) for Lightning
Protection of Nuclear Power Installations).
Easy testing with LifeCheck
Pluggable SPDs and corresponding test adapters can only be tested in a
time-consuming way, as the SPD modules have to be removed, tested and
then plugged in again. Moreover, the signal circuit is unprotected during
the test. LifeCheck allows for quick and easy SPD testing. Removing the
module is no longer required. Being integrated into the SPDs, the RFID
system used requires no batteries or power supply. The proper condition
of the SPD is constantly controlled. An extreme thermal or electrical load
is detected reliably and can be registered with DEHNrecord DRC LC M1
reader in a second and without contacting.
Signal before damage
The control device of the SPD is designed to generate a signal as soon as
the SPD is threatened to be overloaded. This helps to take precautionary
measures to avoid standstills within the installation.
The control indicator system consists of two operating units:
1. RFID Reader:
This consists of a hand-held device with indicator and antenna. The
reader transmits energy to the RFID transmission unit (transponder)
within the SPD without contacting. This reads out the operating state
and displays the same.
2. Control unit within the SPD:
This controls the protective circuit for impermissible overloads by
thermal (overheating) or electrical (impulse currents) incidents. The
control unit is connected directly with the transponder. If an overload
is detected, the affected protection module has to be replaced.

In order to provide a simple and clear indication, the LifeCheck circuit
within the SPD was designed to ensure that the communication is interrupted
whenever an overload has been detected. The actual indication is
performed by DEHNrecord DRC LC M1 test device.

Lightning Current / Surge Arrester
The LifeCheck circuit within the SPD detects two types of overloads:
1. Thermal overloads
If the discharge elements are working in the critical temperature
range, thermal fuse elements interrupt the RFID communication permanently.
2. Electrical overloads
If construction elements are threatened to be destroyed by peak
overloads, the transponder interrupts the communication permanently.

Overloaded SPD modules have to be replaced as soon as possible in
order not to threaten the availability of the installation.
