Circuit breaker condition monitoring SSCBR

Identification

Function description IEC 61850 Identifica-
tion
Circuit breaker condi- SSCBR
tion monitoring

Functionality

The circuit breaker condition monitoring function SSCBR is used to monitor different
parameters of the circuit breaker. The breaker requires maintenance when the number
of operations has reached a predefined value. The energy is calculated from the measured
input currents as a sum of I
exceed the threshold settings.
The function contains a blocking functionality. It is possible to block the function outputs,
if desired.

Operation Principle

The circuit breaker condition monitoring function includes different metering and mon-
itoring sub-functions. The functions can be enabled and by blocking signal in application.
The operation of the functions can be described with a module diagram. All the modules
in the diagram are explained in the next sections.
