Figure 9.2-5 PF sign matched with the sign of the P value (i.e., [PF sign]=AP)
AP+PR setting
(ii)
When the plus or minus sign of the PF value is required to be in conjunction with the states of
the leading current (i.e., supplying power) and the ragging current (i.e., absorbing power), the
user should set AP+RP for the set [PF_sign]. Note that the plus or minus signs of the P and Q
values cause the difference from the sign of the PF value; thus, the user should figure out the
correspondences between the settings [Power] and [Current] of Figure 9.2-6.
