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 “On” and “Off”. The
operation counters are cleared when
Operation
is set to “Off”.
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.
