Operation principle
The circuit breaker condition monitoring function includes a number of metering and
monitoring subfunctions. The functions can be enabled and disabled with the Operation
setting. The corresponding parameter values are Enable and Disable. The operation
counters are cleared when Operation is set to Disabled.
The operation of the functions can be described by using a module diagram. All the
modules in the diagram are explained in the next sections.
