4.3.14.10.21 Oversampling buffer
4.3.14.10.21.1 General information
A Sample Line contains the present values for currents (4 channels) and voltages (3 channels), as well as a
consecutive number and the network time when transferred from the transformer. These values are recorded in
an interval of 125 µs * prescaler.
The user must then scale the values to respective physical values:
Voltage:
Vrms = (INT32)Vs * 4 / Sqrt(2)
Current:
Irms = (INT32)Is * 4 / Sqrt(2)
