PACiS GTW gateway
Suppression (Automatic) A binary information belonging to a bay in SBMC mode will be
automatically suppressed for the remote control. However
changes of state will be signalled locally, at SCP.
Suppression (Manual) A binary information can be suppressed by an order issued from
an operator. No subsequent change of state on a “ suppressed
information ” can trigger any action such as display, alarm and
transmission.

T-BUS Telecontrol Bus
Generic name of networks and protocols used to communicate
between PACIS Gateway or MiCOM C264 Telecontrol Interface
function and the RCP. Networks are based on RS232, 485, or
ethernet (T104). Protocols are IEC 60850-5-101 (T101), IEC
60850-5-104 (T104), Modbus MODICON, OPC, IEC 61850,
DNP3.0 Level3
TIU Transformer Input Unit
Topological interlocking
Interlocking algorithm, based on evaluation of topological
information of the switchgear arrangement in the HV network,
the switchgear kind and position, and defined rules for
controling this kind of switch (e.g. continuity of power supply)
TPI Tap Position Indication (for transformers).
Frequently acquired via a Digital Measurement
UCA
Utility Communications Architecture
Communication standard (mainly US) used for PACIS SBUS
communication
UPI Unit Per Impulse
Parameter of counter to convert number of pulse to
Measurement value. Both data (interger and scaled float) are in
common class UCA2 Accumulator.
UTC Universal Time Coordinates (or Universal Time Code)
Naming that replace GMT (but it is the same)
VDEW
Term used for IEC60870-5-103 protocol
Voltage level
Set of bays whose plants and devices are dealing with the same
voltage (e.g. 275kV, 400 kV).
VT
Voltage Transformer
Basically the electric device connected to process and
extracting a voltage measurement. By extension part of a
device (MiCOM C264) that receives this AC value and convert it
to numerical measurement value. VT are wired in parallele.
WYE Voltage Transformer connection: 3 neutral values.
