EQUATIONS: Vsa = KrFrIpa
NOTES:
Fr << SRF
1. Output Voltage is proportional to the derivative (di/dt) of the input current based on the
Rogowski Coil principle.
2. All current and voltages assumed to be sinusoidal waveforms at Fr, the constant rated
frequency in Hz, measured as RMS values.
3. Accuracy Class per IEC 60044-1 Table 11 where:
⢠Percentage current error = ((Krâ¢Frâ¢Ipa - Vout) / Vout) x 100
⢠Phase displacement = the difference between the primary current (Ipa) phase vector and
the (secondary voltage (Vout) phase vector minus 90 degrees), in minutes
4. Kr = Rated transformation constant
5. Ls = Secondary winding inductance
6. Rs = Secondary winding resistance
7. SRF = Self Resonate Frequency
8. Ipa = Actual primary current
9. Vsa = Actual secondary output voltage
