ZG logic
(ii)
Figure 2.1-45 to Figure 2.1-50 to shows the ZG logics and corresponding SOTF logics. All logic
operations (Z1G, Z1GX, Z2G, Z3G, Z4G, and Z5G) can be selected using the scheme switches.
Scheme switch [Z*G-EFL] is used to select the EFL element for the detection of earth faults;
when the EFL element operates, detection of the PSB is canceled.
Scheme switch [Z*G-LPBlk] is used to enable blocking of the operation of the leading-
phase-block function. The ARC_BLOCK signals allow the Z*G element to perform final three-
phase tripping for all faults. The Z*G_3PTP configures the Z*G element to perform the three-
phase trip.
