PDV/PVR DISTRIBUTION ARRESTERS
Installation Instructions: 17-5122
Introduction
Hubbell Power Systems surge arresters are designed to limit
surge voltage by conducting the surge current to ground,
and thus avoiding equipment damage. The arresters are of
single pole design, suitable for outdoor use, and designed in
accordance with the latest revision of industry standard IEEE
C62.11 and/or IEC 60099-4.
Each PDV and PVR distribution arrester contain a number of
vertically stacked zinc oxide valve elements overwrapped with
an epoxy-impregnated fiberglass filament wrap, contained within
ESP® polymer weathershed housing(s).
Application
Packaging
PDV and PVR arresters are typically packaged in sturdy
cardboard boxes and stacked on a wooden pallet. Some
arresters may be packed in wooden crates or multi-cell
containers. Hardware and mounting accessories will be
assembled to the arrester or contained within the box or crate.
Initial Inspection
Rough handling can result in damage to the surge arrester.
Arresters should be carefully removed from the carton or
container for inspection. If damage is apparent, do not install
the arrester. Claims for shipping damage should be registered
immediately with the common carrier.
The arrester model number, rated voltage (Ur for IEC arresters),
and MCOV (Uc for IEC arresters) are identified on the arrester
nameplate. The nameplate information should be checked
against the shipping memorandum.
The drawing below shows the typical information contained on
the nameplate. The nameplate information is found on the top
metal plate of the arrester. Additional nameplate formats are
used for customer specific requests.
Installation
Install the arrester electrically as close as practicable to the
equipment to be protected. Keep the arrester connections short
and direct.
The arrester insulating bracket should not be modified or
tampered with as this could result in impaired operation of the
ground lead disconnector. Additionally, the top and bottom
sealing bolts of the arrester should not be loosened or otherwise
modified as this may compromise the arrester seal integrity.
For arresters with mounting brackets, such as transformer or
NEMA crossarm brackets, the following illustration shows the
recommended arrangement for fastening the optional bracket to
the insulating bracket of the arrester. A star washer or serrated
washer should not be used in conjunction with the insulating
bracket as this can cause damage to the assembly.
!
CAUTION
The equipment covered by these instructions should be installed and serviced only by competent personnel familiar with
good safety practices. This instruction is written for such personnel and is not intended as a substitute for adequate training
and experience in safe procedures.
!
WARNING
Prior to installing this product, check the nameplate information to verify that it is the correct product for the
application. Verify that the nameplate information corresponds to the information provided on the outline drawing.
!
WARNING
PDV and PVR Distribution arresters must be applied
where the continuous phase-to-ground voltage at
the arrester location does not exceed the arrester
continuous voltage capability as indicated on the
nameplate. Arrester physical size may not determine
the voltage rating. Do not install arrester if type, rated
voltage (Ur for IEC arresters) and maximum continuous
operating voltage (Uc for IEC arresters) are not exactly
the same on the nameplate and packaging labels.
