Circuit Diagrams
The following diagrams show the equivalent circuit of the measuring devices.
Leakage current readings are generated by measuring the voltage drop across these
networks and dividing by the equivalent DC resistance. The volt meter is placed
across the entire network of measuring device A, B and D, but is placed across the
points indicated by the solid black dots on measuring device C and E, as specified
in the agency specifications that apply to the particular measuring device.
