Measuring Earth Leakage Current

Figure 17. Leakage Current Main Menu
Note
The display shown in Figure 17 is the main leakage current menu when AAMI is the selected standard.
All leakage currents, with the exception of Lead Isolation (Mains on Applied parts), are displayed in one of three ways: AC+DC, AC Only, or DC only. The initial result is displayed in the appropriate parameter based on the standard selected. To change the displayed parameter, press Gor H. The present measurement method is displayed to the right of the current measurement while leakage current tests are conducted.
Note
The Ground Wire (Earth) Leakage test is available for AAMI, 60601, and not IEC 62353.
To measure the current flowing in the DUT’s protective earth circuit, press the softkey labeled Ground Wire (pending the standard) from the leakage current main menu. Figure 18 shows the electrical connections between the Analyzer and the DUT during a Ground Wire Leakage Current Test.
Within the Ground Wire Leakage Current test there are a few combination measurements that can be performed. Pressing Pswitches the polarity of the mains voltage applied to the Analyzer’s test receptacle between Normal, Off, Reverse, and Off. Pressing Nopens and closes the neutral connection to the Analyzer’s test receptacle. There is no need to open up the test receptacle earth (ground), since this is done internally during the measurement.
The following outlet conditions apply when performing this test:
•Normal Polarity
•Normal Polarity, Open Neutral
•Reversed Polarity
•Reversed Polarity, Open Neutral
