1 Executive SummaryHubbell Power Systems (HPS) qualifies the seismic capability of its surge arresters to IEEE
693-2005. This report qualifies that standard HPS SVNH arresters, up to the size of the unit
in this report, meet the High Performance Level as demonstrated by a shake table test on a
test stand. An amplification factor of 2.0 was used for Performance Level testing according
to the provisions within IEEE 693-2005. With inclusion of the 2.0 amplification factor, the
sample was tested to a 1.0g ZPA level.
Seismic tests in accordance with IEEE 693-2005 were performed on an SVNH arrester with
a mass of 910 pounds (the measured mass includes 25 pounds added to simulate the line
end terminal connection per the standard), a height of 161.5 inches and a center of gravity
(COG) of 80.8 inches above the base. The arrester was mounted on a 96 inch test stand,
which was mounted to the shake-table interface plate.
To be qualified to the High Seismic Performance Level, IEEE 693-2005 requires that the
tested surge arrester survives the shake test with no structural damage and that it remains
functional. Functionality is demonstrated by successfully passing routine production tests
after the shake table test. These tests consist of measurement of Reference Voltage, Watts-
loss, Discharge Voltage, Partial Discharge and Seal Leak Rate.
The tested surge arrester met all requirements identified above for the High Seismic
Performance Level (1.0g ZPA). Thus, all SVNH surge arresters which do not exceed the
height, mass and COG of the test sample are also qualified to the High Seismic
Performance Level of IEEE 693-2005.

2 Key Information and Results
2.1 Description of Equipment to be Tested and Critical Load LimitsTo accommodate the existing attachment points, a base plate was used to attach the UUT
onto the shake table using (16) 1” -8 threaded studs. The UUT pedestal was bolted directly
to the base plate using (3) 1” Grade 5 bolts and (1) 1” Grade 5 strain bolt. The surge
arrester was bolted directly to the top of the pedestal using (3) ¾” Grade 5 strain bolts. A
summary of the UUT is provided below. Data and calculations supporting the summary of
results and determination of controlling variables are provided in Appendix C.

MCOV, the unit passes this test if it exhibits a PD level of 10pC or less.
3. Reference Voltage – Voltage at which arrester conducts 17 mA of peak resistive current.
Acceptable ranges are given below.
4. Power Frequency (PF) Test – PF Voltage applied at 1.2 x MCOV. Power loss (Watts Loss) limit
given below.
5. Leakage Check – Seal integrity verified by Helium Mass-Spectrometer.

M14-07-66 Composite Polymer Shed Seal Test- IEEE 693-2005 Section A.4.4 on part-
PSESVNXUAG5126
The cantilever/ dye portion of this test was performed at an external lab then shipped to
Wadsworth for sample dissection.
Sample as received:
The sample was first cut approx. 2” above the lower end fitting across the fiberglass core and
then locations were marked for vertical cuts and location on the tested fitting/ core.
Photos of the post cut part:
Photos of end fitting sections showing no presence of dye:
Photos of fiberglass core showing no presence of dye:
No dye was found within 2mm of the fiberglass core after testing and dissection.
