Temperature Supervision
Overview of Functions
6.47.1
The Temperature supervision function checks the thermal state of:
•
Motors
•
Generators
•
Transformers
In rotating machines, it also checks bearing temperatures for a limit violation.
The temperatures are measured at various locations of the protected object using temperature sensors (RTD =
Resistance Temperature Detector) and are sent to the device via one or more RTD units.
The Temperature supervision function receives its measured temperature values via the RTD unit Ether. or
RTD unit serial functions from the Analog units function group.
Structure of the Function
6.47.2
The Temperature supervision function can work in all protection function groups. A maximum of 48 tempera-
ture supervision locations can operate simultaneously in the Temperature supervision function function.
Each temperature supervision location has 2 threshold stages.
