Waveform recorder data structure (WFR log)
The waveform recorder data contains the values of the secondary side. The voltage
data returned is 10 times of the actual secondary voltage and the current data is
1,000 times of the actual secondary current. The voltage and current values of the
primary side are calculated as follows:
U
primary
= U
secondary
x voltage transformer transformation ratio/10
I
primary
= I
secondary
x CT transformation ratio/1,000
