Motor current analysis can be performed with the
EVAM vibration analysis technique using a current
clamp(e.g.Flukei1000s)orapermanentlyinstalled
current tranformer connected to the VIB input.
This feature is used for troubleshooting, primarily
onelectricalmotorswithatleast70%workload.
NOTE: It is important to follow safety precau-
tions and that the measurement is performed
by authorized personnel.
In order to use a current clamp, a user defined
transducer is to be set up. Fluke i1000s is the type
of current clamp used in this example.
