Earth leakage testing device
WebOct 7, 2024 · Earth leakage is electric current that finds its way to earth via an unintended path. There are two categories: unintentional earth leakage, which results from faulty insulation or equipment, and intentional earth leakage, which is a consequence of the way equipment is designed. It seems strange to “design in” earth leakage, but it’s ... WebThe first way of testing an earth leakage is to adopt an isolated power system (IPS). An IPS is typically combined with insulation monitoring devices that differentiate the imbalance between neutral and line conductors. The IPS method is a less frequently used method of conducting earth leakage testing.

WebAny leakage current flowing in the green safety ground wire would be seen as a non-zero reading at position #2, and any leakage current from the load to earth would show a non-zero reading at positions #2 or #3. Since the green wire is included in the test at position #3, only the ground current is registered as leakage in that case.
