Sensed Currents
Phase Current — Individual Phase Currents:
Range: 1 A to 10,000 A for 500:1 CTs
2 A to 20,000 A for 1000:1 CTs
4 A to 40,000 A for 2000:1 CTs
Accuracy: ± 1 mA from 10 mA to 125 mA
0.8% from 125 mA to 1600 mA
(Control only – does not include sensor
tolerance.)
Ground Current — Vector Sum of Three-Phase
Currents:
Range: 1 A to 5,000 A for 500:1 CTs
2 A to 10,000 A for 1000:1 CTs
4 A to 20,000 A for 2000:1 CTs
Accuracy: ± 3 mA from 10 mA to 125 mA
2.4% from 125 mA to 1600 mA
(Control only – does not include sensor tol-
erance, but does include the phase current
summing process.)
