Power (Energy) Meter

The Power Meter displays Total, Forward and Reverse energy through the switchgear in kilowatt hours.

It can be displayed in WSOS by selecting the Display Power Measurement button on the Measurement page.

These readings are not displayed on the setVUE O.I. but can be found on the flexVUE O.I. at:

Engineer Menu > Measurements Menu > Energy.

Depending on the Signed/Unsigned setting, the Total (kWh) represents either the net energy flow or the total accumulated energy flow.

If Power is signed and equal amounts of energy flow through the switchgear in each direction, they would cancel each other out and the total would be zero.

If Power is unsigned, Total would read the accumulated energy flow irrespective of the flow direction.

The integrated real energy flow in both the forward and reverse directions are also measured independently.

Power Meter measurements can be reset to zero with the WSOS Erase Settings and History command.

They can also be reset with the appropriate communications protocol command.

All three values are available for Configurable History logging.
