Measuring range: see V RMS and A RMS measurement
Power errors are calculated by adding the errors of voltage and current.
Additional error due to power factor PF:
Specified error x (1-IPFI)
Maximum Range with Voltage range 830 V delta-connection and 3000 A
current range is 2.490 MW
Intrinsic error: ± (0.7 % of m.v. +15 dig)
Resolution: 1 kW
Operating error: ± (1.5 % of m.v. + 20 dig)
Typical Range with Voltage range 230 V Wye-connection and 150 A current
range is 34.50 kW
Intrinsic error: ± (0.7 % of m.v. +15 dig)
Resolution: 1 W to 10 W
Operating error: ± (1.5 % of m.v. + 20 dig)
The errors of the current sensors themselves have not been considered.
Energy Measurement (kWh, KVAh, kVARh)
Intrinsic error: ± (0.7 % of m.v.+ F variation error*
+15 dig)
Resolution: 1 W to 10 W
Operating error: ± (1.5 % of m.v. + F variation error* +
20 dig)
* Frequency variation error ± 2 % m.v. + 2*(% maximum frequency
deviation)
