| SAFETY | |
| Electrical safety | EN61010-1, EN61010-031, EN61010-2-031, EN61010-2-032 standards |
| (1) Conditions of reference | 23 °C ± 2 °C, 20% to 75% RH Position of conductor measured: centred in the measurement coil Shape of measurement coil: quasi-circular Measurement instrument input impedance (oscilloscope) ≥ 1 MΩ Frequency and form of signal measured: 40 to 400 Hz sinusoidal |
| (2) Output levels | The Rogowski coil output is proportional to the rate of change of current. The calculation formula is: Ampere rms x Hertz x K x 10-6, where K depends on manufacturing. The K value is 2 for 100 mV model and 0.8 for 40 mV model. |
