The equation above also implies that each individual binary output corresponds actually to one
integer, which is presented in the input ZONCONI and can be defined by:
CZ
×2
6
or
ZONEx
×2
x-1
, (1≤x≤6).
Refer to Table 47 for the description of such representations.
Table 47: Integer representations for the binary outputs of BCTZCONN

ZONE1 BOOLEAN Bay is connected to Z1 0 1
ZONE2 BOOLEAN Bay is connected to Z2 0 2
ZONE3 BOOLEAN Bay is connected to Z3 0 4
ZONE4 BOOLEAN Bay is connected to Z4 0 8
ZONE5 BOOLEAN Bay is connected to Z5 0 16
ZONE6 BOOLEAN Bay is connected to Z6 0 32
CZ BOOLEAN Supervision status of the check zone
on differential zones (Valid only for
feeder bays)
0 64
Figure 194 shows an example how to use BCTZCONN to facilitate the recording of the zone
connection information from one bay, say feeder 01, to a disturbance recorder in ACT for any
six-zone busbar differential protection application.
