Phase current input characteristics are as follows:
o
Measurement range
Phase currents 0…250 ARMS
Coarse residual current 0…150ARMS
Fine residual current 0…75ARMS
o
Angle measurement accuracy less than ± 0.5 degrees with nominal current.
o
Frequency measurement range of the phase current inputs is in range from 6 Hz to
1800 Hz with standard hardware.
o
Quantization of the measurement signal is applied with 18 bit AD converters and the
sample rate of the signal shall be 64 samples / power cycle in system frequency
range of 6 Hz to 75 Hz.
