Table 7

Inom is the measured current when the output from the current sensor is 1V.

Pnom and Snom are the active and apparent powers for V = 1,000 V, I = Inom, and PF = 1.

Qnom is the reactive power for V = 1,000 V, I = Inom, and sin ϕ = 1.

The intrinsic uncertainty of the current inputs is specied for an isolated voltage input of 1V, corresponding to Inom. The intrinsic

uncertainty of the current sensor used must be added to it to determine the total uncertainty of the measurement system. With

the AmpFlex® and MiniFlex® current sensors, the intrinsic uncertainty given in Table 20 must be used.

If there is no current sensor, the intrinsic uncertainty on the neutral current is the sum of the intrinsic uncertainties on I1, I2, and I3.

If there is no current sensor, the intrinsic uncertainty on the neutral current is the sum of the intrinsic uncertainties on I1, I2, and I3.

With the AmpFlex® and MiniFlex® current sensors, the maximum current is limited to 60% Inom at 50/60Hz.
