How To Test Neutral Earth Fault. That the protection operates on the occurrence of an earth fault it is necessary to calculate the earth fault loop impedance Z s and ensure that the fault. Somewhere in between it will be necessary to do something to prevent the earth faultshort circuit and a nice round figure of 1 MĪ© is probably as good as any.
Line voltage leakage tests are typically required on all medical products as a production test. That the protection operates on the occurrence of an earth fault it is necessary to calculate the earth fault loop impedance Z s and ensure that the fault. The Earth Fault Loop test sequence.
This is a live test so extra care is advised.
Locate the furthest point on the circuit to be tested such as the furthest socket Step 2. The neutral and the earthed parts are only connected together via an electrode system back to the source earth and neutral. As Chris says it is the change that is of most interest. Somewhere in between it will be necessary to do something to prevent the earth faultshort circuit and a nice round figure of 1 MĪ© is probably as good as any.
