Notes:
Consider any displayed warning before starting measurement!
Substitute leakage current may differ substantially from that of conventional
leakage current test because of the way the test is performed. For example, the
difference in both leakage measurements will be affected by the presence of
neutral to earth noise suppression capacitors.
6.4 Leakage current and power
The purpose of this test is to determine the sum of all leakages flowing from the live
conductor to the earth. Because the differential method for determining leakage current
is used the full and true appliance leakage current is always measured, although there
can exist parallel current paths to ground.
Also the apparent power is measured. By checking the power an efficient functional test
can be performed.
