Portable Appliance Tester

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® Excel.

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.

FEATURES AND BENEFITS

Large 5.7” ¼ VGA backlit color screen for clear results

200mA; 10A and 25A bond test with high duty cycle for

repetitive testing

250V and 500V insulation tests protect sensitive electronics

Selectable PASS/FAIL limits provide instant indication of a

faulty asset

120 V 60 Hz operation for industrial, commercial and

residential applications

Simplified menus for easy intuitive operation

Instant restart for faster testing across multiple rooms

Adjustable test times allow faster testing

Tests for standard and anti-surge extension leads

Operational test including VA display for a complete testing

range

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.
