CT inputs neutral side
Figure 17 shows DGPR CT connections for the neutral side. AH1, AH3, and AH5 are for
current inputs, while AH2, AH4, and AH6 are for common return. AH7 and AH8 are used for
INR in the DGP, but they are used for 51G or GPM connection in the DGPR.

Voltage inputs
Figure 18 shows DGPR VT connections for WYE and Open Delta connected VTs. The DGPR
phase voltage inputs and Vx are derived from the generator terminal voltage and
generator neutral ground transformer, respectively.
The jumpers for both VT connection types are labeled and provided with the DGPR unit.
Verify the VT connection type and fix the jumpers accordingly.
