PrimeTest 350 Operating Instructions
- 55 -
During this test, a nominal voltage of 40V a.c. rms is
applied between the earth pin and both the live and
neutral pins of the appliance mains supply plug.
The tester measures the current that flows and scales
the result to display a guide to the current that would
flow if the test voltage had been the nominal mains
supply voltage. See 10.1.5 Sub Leakage scale factor.
The Tester displays the result in milliamps (mA).
This test can prove useful in situations where neither
conventional insulation nor flash tests are acceptable
methods of testing the insulation of the appliance.
Please note that values for substitute leakage may
differ substantially from that of conventional earth
leakage tests because of the way that the test is
performed (e.g. it will be affected by the presence of
Neutral-to-Earth suppression capacitors).
11.4 Protective Earth (PE) Conductor Current
Refer to Fig 5
This test is applicable on Class I
Equipment.
The Protective Earth (PE) Conductor Current Test
displays the current flowing in the earth conductor of
the EUT. This is measured by looking at the difference
in current flowing in the live and neutral conductors.
The Tester displays the result in milliamps (mA).
In the top left area of the screen, the tester also
displays the EUT load in kVA.
Warning: Always test the earth continuity
and insulation resistance before performing
a PE Conductor Current test.
Warning: Always check that an appliance
with moving parts (e.g. an electric drill) is
safely mounted to avoid risk of damage to
equipment or personnel.
