Counter Value Scaling
Scaling
The scaling of the metered measurands, which are derived from measured values, refers to:
60 000 impulses per hour for V = V
V
prim
I
prim
Example
The following is configured in the parameter set:
I
= 1000 A and V
prim
60 000 impulses correspond so that:
1 h * 1000 A * 400 kV *
NOTE
•
The type of the update (cyclic, with or without deletion) and the update interval must be programmed for
the metered measurands with the parametrization software DIGSI 4.
•
The scaling of the metered measurands at binary inputs Wp(puls) and Wq(puls) depends on the externally
connected pulse generator.
