Context of Application
An installation is designed with specific circuit breaker settings, calculated to optimize the protection of the installation. However, throughout the life cycle of the installation, these settings may not be applied correctly or may be modified (for example during maintenance, product replacement, or due to nuisance tripping).
An incorrect setting may lead to:
-
Nuisance tripping if the threshold is too low
-
The tripping of an upstream circuit breaker instead of the local circuit breaker if the selectivity is ineffective
-
Device destruction, fire outbreak, and/or personal injury if the coordination between products is not correct
Problem to Solve
The facility manager needs to:
-
Be confident that electrical protection devices are able to fulfill their function.
-
Help prevent issues due to inappropriate or poorly coordinated circuit breaker settings.
Purpose of the Application
Manually or automatically generate a report summarizing settings of LV circuit breakers:
-
Easily compare commissioned settings with designed settings to establish a validated baseline
-
Compare actual circuit breaker settings with commissioned settings
-
Periodically detect inappropriate setting modifications
-
Provide information for capacity planning
This report helps to identify settings or coordination issues and to find the root cause of any settings or coordination problems.
