LEAKAGE TEST
LOAD TESTS
leakage Test
Warning
Mains voltage applied to appliance
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.
Touch leakage Test
Warning
Mains voltage applied to appliance
The Touch Test displays the current that would flow if the appliance was
touched by a person. This is based on a ‘body model’ of 2kΩ.
The Tester detects any current flowing in the Earth Bond Lead (attached to
an appropriate point on the appliance) and indicates the potential leakage
through a metal panel. The Tester displays the result in milliamps (mA).
load Test
Warning
Mains voltage applied to appliance
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 test is
cancelled. This will allow appliances with slow start-up speeds the time to
ramp up to their working state.
