Example of Power Quality setup using the Wizard
Current Probe
Select the current probes you are going to use from the list. If you are using LEMFlex make sure the
probe and list match exactly. Full scale current should not exceed probe rating and nominal current
should not be less than 10% of full scale.
Scale Factors
Set Scale factors if working with the secondary of PTs or CTs. If your Probe is in the list and selected,
Amps Scale Factor should be 1 if not connected to a secondary of another CT.
Circuit Type
Select the circuit type. If you see a mismatch while connected you may not be connected properly or
your current probes are reading <10% of full scale or could be V or I imbalance. You can choose to
override and monitor anyway although not recommended if connection is wrong.
Nominal Values
If connected the unit will show values it is reading. If you are not connected, then you can set your values
by pressing the blue bordered box.
