3.1.8 Description of 1 ph package B31
SEMOD129275-58 v8
One-phase version of the IED with two low-impedance differential protection zones and
twenty-four CT inputs B31.
• The IED is intended for busbar protection applications in big substations where dynamic
Zone Selection, quite large number of binary inputs and outputs and many CT inputs are
needed. The IED includes two differential zones and twenty-four CT inputs. Note that
binary inputs can be shared between phases by including the LDCM communication
module. This simplifies panel wiring and saves IO boards.
