  • Page 45 As the images above show, the scaling selection does not affect how primary and secondary currents are displayed (as actual values). The only effect is that the per-unit system in the relay is scaled either to the CT nominal or to the object nominal, making the settings input straightforward. © Arcteq Relays Ltd...

    Measurement sampling can be set to the frequency tracking mode or to the xed user- de ned frequency sampling mode. The bene t of frequency tracking is that the measurements are within a pre-de ned accuracy range even when the fundamental frequency of the power system changes. © Arcteq Relays Ltd...
  • Page 55 This has been achieved by adjusting the sample rate of the measurement channels according to the measured system frequency; this way the FFT calculation always has a whole power cycle in the buffer. The measurement accuracy is further improved by Arcteq's patented calibration algorithms that calibrate the analog channels against eight (8) system frequency points for both magnitude and angle.
