DESCRIPTION

Operators of electric tools and other electrical equipment
must be protected from potentially dangerous flaws in
workmanship or wear and tear. The PAT450 is designed to
test portable electrical equipment for safe operation. The
tests conform to the latest editions of European regulations
and standards including VDE0701-0702 and the Code
of Practice for the In-Service Inspection and Testing of
Electrical Equipment in the UK.

The PAT450 has a memory capacity for storing up to 10,000
test results, and also 10 A and 25 A earth bond testing.
The unit also includes 1.5 kV and 3 kV flash testing, ideal
for tool rental outlets and service workshops where flash
testing is routine. It has a high duty cycle, with the design
tailored to fast testing, easy operation, and all-day use.

The PAT450 features a unique restart, so that when moving
the tester from one room to another, it restarts instantly
from the same menu where it was unplugged. This is a
significant timesaver, allowing more tests per day.

USB communication provides convenient download to a
standard USB memory stick. An on-board 10,000 record
memory provides interruption-free testing for improved
efficiency, with a large QWERTY keypad for fast data
entry. The instrument is capable of working with standard
barcode scanners and a thermal transfer barcode label
printer operating directly from the USB port. Thermal
transfer labels are highly resistant, stable and easily
available.

Five soft-keys give direct access to frequently-used
functions, accelerating navigation through menus and
increasing productivity. Both standard and customer
configurable test groups are available for fast, flexible asset
testing.

Accessories supplied include a combined earth-bond and
insulation test lead, an adapter for testing 120 V extension
leads, a laptop power supply adapter, and a carry case for
convenient product and lead storage. All instruments also
include download manager software, to enable data to be
converted into a CSV format which can be read directly on
a PC using Microsoft

TYPE OF TESTS

Earth Bond and Continuity Tests

To verify the integrity of exposed metalwork on grounded
(Class I) appliances. Test current of 25 A is passed via a
remote probe, returning through the Ground pin of the
power plug.

Test currents of 10 A and 25 A are available for bond
testing. Where sensitive electronic equipment may be
damaged by high currents, 200 mA is selectable.

Insulation Test

To check that equipment conductors are isolated from
ground - 500 V dc; the live and neutral conductors are
linked; and the test voltage is applied between this link and
the ground pin. Where an appliance does not have an earth
connection (Class II), the remote probe is used to contact
anywhere on the external case of the equipment.

Where 500 V may damage sensitive equipment, the
PAT450 provides alternative methods of verifying insulation
integrity. A lower voltage of 250 V dc is selectable, or
alternatives such as a touch current test or substitute
leakage test can be performed.

Portable Appliance Tester

Touch Current Test

This test powers the asset at the supply voltage as if it were
in use. The current passing down the earth conductor is
displayed. For Class II, the remote probe is used to contact
any accessible conductive parts.

Differential Leakage Test

Similar to the touch current test, during operation the
difference in current between the live and neutral conductor
is measured.

Substitute/Alternative Leakage Test

This test is performed in the same method as the insulation
test, i.e. between the earth conductor and linked live/
neutral. For Class II, the remote probe is used to contact any
accessible conductive parts of the asset.

An ac voltage ac voltage (nominal 40 V at supply frequency)
is applied and the leakage current measured. As this is at the
same frequency as the supply, the impedance of any leakage
path is the same as that when the asset is in operation.

Functional Load Test

Operational test to ensure that the asset works as it should.
Supply voltage is applied to the asset when in use.

Simultaneously, the VA value is displayed as an additional
check that the current drawn by the asset is as expected.

Extension and IEC Power Cords

Standard insulation and earth-bond tests are performed, with
an additional polarity test, to ensure that the lead is wired
correctly.

Hi-pot/Flash Test

Where the application requires a hi-pot/flash test, a high
voltage is applied to any exposed conductive parts via a
probe. The leakage current between the linked live/neutral
conducters and the probe is monitored, and any electrical
breakdown indicated. For Class I, the test voltage is 1.5 kV
ac; for Class II it is 3 kV ac.

APPLICATIONS

While the USA does not have the level of regulation found
in the UK, we are far more litigious. Implementing a regular
inspection program that includes PAT testing of electrical
equipment and appliances will help protect personnel from
shock hazards, facilities from electrically induced fires and
businesses from litigation. For businesses that manufacture
and ship electrical products to the European Union, PAT
testing at the factory will ensure that products shipped will
pass import testing and not become a costly problem.

Ideal for portable appliance testing in locations like service
workshops, hotels, schools, hospitals, prisons, long term
care facilities, construction sites, offices, restaurants and
sport facilities, the PAT450 can store up to 10,000 test results.
It features 10 A and 25 A bond tests with high duty-cycle
designed for fast testing, easy operation and all-day use.
The PAT’s 250 V and 500 V insulation tests protect sensitive
electronics.
