Appendix A Purpose of Tests
48
Leakage Test
The Leakage Test shows the current being lost through Leakage as
the difference in the currents flowing in the Live and the Neutral
conductors. This difference is the total leakage away from the
appliance, and is generally equivalent to the current flow through the
Earth lead of the appliance, and displays the result in milliamps
(mA).
This differential method of determining leakage will show the full
leakage of an appliance in-situ, so if the appliance has an extra
Earth point, i.e. water pipe, then the Tester will show the full and
true appliance leakage. This is also known as Enclosure or
Differential Leakage.
Power Test
The Power test supplies the equipment under test, connected to the
power outlet test socket, with the rated voltage of that socket.
The Tester measures the power used by the appliance and displays
the reading in kVA. There is no test duration limit on the Power
tests. Once supplied with power, the appliance will be supplied until
the operation is cancelled. This will allow appliances with slow start-
up speeds the time to ramp up to their working state.
