Formula for calculating the inductive voltage drop:
U
r
Ohmic resistance load in Ω/km
U
x
Inductive resistance load in Ω/km
I
N
Nominal current (amps) of selected current-trans-
former connection on device:0.2 A; 1 A; 5 A
k
CT
Current transformer ratio
k
VT
Voltage transformer ratio
r Ohmic resistance load in Ω/km per phase
x Inductive resistance load in Ω/km per phase
L Length of line in km
K Nominal current factor
Setting the ohmic voltage drop Vr
You can use this parameter to set the ohmic voltage drop (ohmic resistance
load).
If you do not want to use line drop compensation, you have to set the value
0.0 V.
To set the ohmic voltage drop Vr, proceed as follows:
1. > Parameter > Compensation.
ð Vr line drop compensation.
2. Press to highlight the position.
ð The desired position is highlighted and the value can be changed.
3. Press to increase the value or to reduce it.
4. Press .
ð The ohmic voltage drop Vr is set.
Setting the inductive voltage drop Vx
You can use this parameter to set the inductive voltage drop (inductive re-
sistance load). The compensation effect can be rotated by 180° in the dis-
play using a plus or minus sign.
