It is possible to calibrate the measuring function above to get better then class 0.5
presentation. This is accomplished by angle and amplitude compensation at 5, 30 and
100% of rated current and at 100% of rated voltage.
The power system quantities provided, depends on the actual
hardware, (TRM) and the logic configuration made in PCM600.
The measuring functions CMSQI and VMSQI provide sequence component
quantities:
• I: sequence currents (positive, zero, negative sequence, amplitude and angle)
• U: sequence voltages (positive, zero and negative sequence, amplitude and
angle).
