Fig 7.3
I1 is the reference and the range is 0-360°. The num-
ber of degrees that voltage (V) is displaced ahead of I1
appears on the display.
Example

Phase displacement caused by an inductive load.
Voltage lies 60° ahead of current. 60° appears on the
display.
7.12 Measuring Z, P, R, X, S,
Q and power factor (cos
ϕ
)
When INGVAR's voltmeter is activated you can meas-
ure impedance (Z), active power (P), resistance (R),
reactance (X), virtual power (S), reactive power (Q)
and power factor (cos
ϕ
).
Scroll through these quantities by pressing the
ESC
button several times. Scrolling is possible even if the
measurement is frozen.
