Electrical test to meet compliance standards
September 1st 2007 Advanced electrical test
instrumentation from Clare
Instruments is helping
Domnick Hunter meet international
compliance standards across a
diverse range of industrial
products. Domnick Hunter
restructured manufacturing
activities at its Industrial Operations
division by amalgamating the
production lines for its PNEUDRI
series of compressed air dryers
with those for its nitrogen and
hydrogen gas generator
equipment ranges.
Clare Instruments supplied and
installed four new stand-alone
electrical test systems based on its
Hal Combi multi purpose tester.
The Hal Combi performs the
complete suite of standard
electrical safety tests and allows
full traceability of test results and
records via internal test data
memory storage.
The new tester performs post
production earth bond, AC/DC hi
pot (flash) and insulation testing on
the compressed air dryers and gas
generators to ensure the
compatibility of products with UL
technical and performance
standards. At Domnick Hunter, the
Hal Combi testers are trolley
mounted to allow ease of mobility
around different production areas.
The testers incorporate preconfigured
test sequences for the
complete range of products, which
are triggered automatically for
repetitive multi-test routines when
product serial numbers are input.
Individual test specifications for
different product groups are also
password protected and operator
safety is maintained by the need to
push two switches concurrently to
run the test sequence, as well as
an auto cut-out facility and isolated
outputs. The test instruments are
accompanied by high visibility
warning beacons, with a green
lamp indicating that the instrument
is energised and ready to apply the
tests, a red lamp is illuminated
while the electrical tests are active. More articles from Clare Instruments C/o Seaward Electronics Ltd: |
