EQUATIONS: Vsa = KrF Ipa
Fr << SRFr
NOTES:
Low Frequency Equivalent Circuit
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:
