Testing The Guardian Plus Terminal; Testing The Hvsc Plus Downconductor - Lightning Protection International GUARDIAN PLUS Installation Manual

∆
Check finial tip for excessive pitting
∆
Check all rigging, mast mounts, saddles and conductor fixings are secure and tight
∆
Ensure that no dirt or other matter is sitting in the air gap between the finial tip and the
surrounding panel edges
∆
If conventional downconductors are used, check that all conductors are securely fixed
and not damaged
∆
Check for damage to the LPI HVSC Plus. The downconductor should not be able to be
accessed by non authorised people or machinery
∆
All warning labels must still be in place
∆
Check LSR1 for secure installation and record number of strikes

Testing the Guardian Plus Terminal

LPI manufactures and supplies a terminal spark-over tester suitable for testing the Guardian
Plus range of terminals. Contact your local distributor for further details.

Testing the HVSC Plus Downconductor

The HVSC Plus downconductor can be tested at various stages of its preparation for service.
These stages and the tests that can be performed are summarised below.
1. Before upper or lower terminations are made (raw cable):
∆
Use a digital multimeter or, preferably, a Megger to measure the continuity between the
inner and outer conductors of the HVSC Plus downconductor. The measurement should be
"open circuit" (exceeding 1 M Ω )
2. After the upper termination is made but before the lower termination is made:
∆
Use a digital multimeter or, preferably, a Megger to measure the continuity between the
inner conductor at the top (upper termination) and the shield (outer copper tape conductor)
at the bottom of the cable. The measurement should give a resistance greater than about
3 k Ω and no more than about 15 k Ω
3. After the upper termination and lower termination are first made:
∆
Use a digital multimeter or, preferably, a Megger to measure the continuity between the
inner conductor at the top (upper termination) and the shield (outer copper tape conductor)
at the bottom of the cable. The measurement should be a "short circuit" (less than 1 Ω ,
excluding the resistance of the leads, the exact value depending on the length of HVSC Plus)
