Metering Features - Eaton Power Xpert Release PXR 10 Manual

1.2 Metering features

The following table shows the electrical system information which is metered by the trip
unit. It is available for viewing in PXPM, on the display (if equipped) or for reading via
communication channels.

1.2.1 Metered data specifications
Metered data accuracy is as follows:
metered value Range of conditions (units)
5 to 10 % of In (A)
Current (I)
10 to 120 % of In (A)
60 to 102 (V)
Voltage (V) 102 to 690 (V)
690 to 750 (V)
5% to 10% of In (A)
102 to 690 (V)
Power factor = 1
Power (kW)
Energy (kWh)
10 to 120 % of In (A)
102 to 690 V
Power factor = 1
10 to 20 % of In (A)
102 to 690 (V)
PF = 0.5 inductive or 0.8 capacitive
Power (kW)
Energy (kWh)
20 to 120 % of In (A)
102 to 690 (V)
PF = 0.5 inductive or 0.8 capacitive
Note: Accuracy is expressed as % of reading, currents are RMS, voltages are line-to-line.
