Charging Current Calculation
From Figure 1:

 Ic=(IG)²-(IR) ²
5.3 Test Results
All components that are operating during testing contribute to the test results. This includes the contribution of
thesurge-protectivecapacitorwhich,asmentionedpreviously,canbequitesignicant.Assuch,thetestresults
shouldbemodiedtoincludeallsurge-protectivecapacitorsnotinoperationduringtesting.
The resulting value should be used to determine a minimum current for ground fault alarming. Set the resistor
taps(seesection2)sothatthefaultcurrentisslightlygreaterthanIC.
NOTE: The temporary disconnect switch and current limiting fuse associated with the phase to be grounded are not
included with the PulserPlus Pro™. A portable ammeter can be included as an option with the PulserPlus Pro™.
