EMR-5000
IM02602012E
Frequency measurement
Nominal frequency:
50 Hz / 60 Hz
Precision:
±0.05% of fn within the range of 40-70 Hz at voltages >50 V
Voltage dependency:
frequency acquisition from 0.15 x Vn
Energy measurement*
Energy counter error
1.5% of measured energy or 1.5% Sn*1h
Power Measurement*
VA, W, VAr:
<±1% of the measured value or 0.1% Sn (for fundamental)
<±2% of the measured value or 0.1% Sn (for RMS)
Power Factor Measurement*
PF:
±0.01 of measured power factor or 1°
I > 30% In and S >2% Sn
*)Tolerance at 0.8 … 1.2 x Vn (with Vn=100V) , |PF|>0.5, symmetrically feeded
Sn=1.73 * VT rating * CT rating
