connection between the BIO module and trip coil circuit is made at the IED
terminals. For more information w.r.t the BO circuit concerning the Element ID
(Data ID), see Chapter
§Note: ARC (Chapter 2.22) and CBF (Chapter 2.12) functions are discussed separately.
‡Note: For information of recording, see
Command for tripping CB and signal to block reclosing CB
2.23.1
The TRC logic is designed to issue a three-pole trip command for any fault. Table 2.23-1 shows
the receipt of trip signals from the protection functions, which are identified by 'Protection
function identification numbers ('
is also provided along with the trip signal; the three-pole trip command 'TRIP-COMMAND' is
generated even if a single-phase fault occurs.
