ION Setup User Guide Configuring ION Setup

Conventions tab

Phasor Rotation: This option lets you select the phasor rotation for real-time

phasor display. You can set the display to rotate clockwise (90 degrees at the 6

o’clock position) or counterclockwise (90 degrees at the 12 o’clock position).

This allows you to alter the phasor display angle so indicators are visible. (See

“Phasor Viewer” on page 103.)

Delta Vector Display: This lets you select how vector diagrams are displayed in

ION Setup for meters in Delta mode:

 Instrument: Vectors appear 60 degrees apart, showing the actual voltage and

current values that the meter is measuring.

 System: Vectors appear 120 degrees apart, showing true system operation

even though IB and VCA are calculated values.

PF Convention: This sets the power factor sign convention.

 IEEE (Lead+/Lag-/0 to 100%: Use for IEEE meters. The sign of the power

factor is converted to lead or lag, and the power factor value is expressed as a

percentage.

 IEC (+/-/0 to 1.000): Use for IEC meters. The power factor sign is not

interpreted, and the power factor value is expressed as a decimal fraction of

one.
