Table 5-35. 2 Winding Through Fault Register Definition For The Tpu2000/Tpu2000R - ABB TPU2000 Technical Manual

TPU2000/2000R Modbus/Modbus Plus/ Modbus TCP/IP Automation Guide
Thirty two through faults are stored within the TPU2000/2000R. A through-fault is stored on any overcurrent trip
output or whenever the Disturbance-2 pickup setting is exceeded. Within the TPU2000 and TPU2000R the two
Winding Through Fault buffer described in Table 5-35 allows the user to obtain the fault information. In a
TPU2000R Three Winding Unit, additional fault information may be retrieved describing the fault conditions for the
third winding.
