Operational Measured Values and Statistical Values
The following applies to the tolerances of currents and voltages:
•
The values apply both to the RMS values and the absolute value and phase angle of the fundamental
components.
•
The values were determined for pure sinusoidal signals – without harmonics.
•
All measured values have an additional tolerance of 1 DIGIT.
