SNTP
See Simple Network Time Protocol.
SOE
See Sequence of Events.
SP
See Single-Point Indication.
SPC
IEC 61850 data type: Single Point Control
SPS
IEC 61850 data type: Single point status
SST
See System Interface.
Station Description
A station description is an IEC 61850-compliant file for data exchange between the system configurator and
the IED configurator. The station description contains information on the network structure of a substation.
The station description contains for example, information on the assignment of the devices to the primary
equipment, as well as on the station-internal communication.
System Interface
Device interface for linking to the control and protection system via various communication protocols
TC
Tap-position command – see Transformer Tap Position Command
TCP
See Transmission Control Protocol.
Time jump
A step change in the device clock due to user action (setting the time) or automatically (GPS time synchroniza-
tion unit). A time jump may occur, for example, in the event of a failure when changing the time synchroniza-
tion source.
Time stamp
A time stamp is a value in a defined format. The time stamp assigns a point in time to an event, for example,
in a log file. Time stamps ensure that events can be found again.
Topological view
The Topological View is oriented to the objects of a system (for example, switchgear) and their relation to one
another. The Topological View describes the structured layout of the system in hierarchical form.
Transmission Control Protocol
The Transmission Control Protocol (TCP) is a transmission protocol for transport services in the Internet. TCP is
based on IP and ensures connection of the participants during the data transmission. TCP ensures the correct-
ness of the data and the correct sequence of the data packets.
