Scaling of Measured Values

3.3 Counter-Value Scaling

3.3 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
where:
V

I

Example:
The following is configured in the parameter set:
I = 1000 A and V
prim
60 000 impulses correspond to the following:
1 h ⋅ 1000 A ⋅ 400 kV = 692.82 MWh

•
For the metered measurands, the type of the update (cyclic, with or without deletion) and the update
interval must be set with DIGSI 4.
•
The scaling of the metered measurands at binary inputs Wp(puls) and Wq(puls) depends on the
externally connected pulse generator.
