action
Check the configuration.
Maximum load
Description Device working at full load
Corrective
action

Low load Power Factor
Description
The power factor value measured is less than 0.7, which might indicate a connection error in the
measuring transformers, where the voltage phases do not correspond to the current phases.
Corrective
action
Confirm that the connections are correct.
Reverse power
Description The power value measured is negative (generated power), which might indicate that the transformers
