6.2.4.3. Intrinsic uncertainty
The intrinsic uncertainties of the current measurements and of the phase must be added to the intrinsic uncertainties of the
instrument for the quantity concerned: power, energies, power factors, tan
Φ
, etc.
The following characteristics are given for the reference conditions of the current sensors.
