  • Page 78: Measurements

    6.0 MEASUREMENTS Basic measurement quantities are calculated and updated every 100 ms. These quantities include RMS Amperes and RMS Volts, Watts, VARs, VAs, Power Factor, all harmonic-based measurements (such as fundamental-only quantities), Energy, and Frequency, and Phase Angle. Note: For all of the following measurements, it is important to keep in mind that the specific protocol used to access the data may affect the data that is available, or the format of that data.

  • Page 79: Voltage Channels

    6.3 Voltage Channels All voltage inputs are measured relative to a common reference level (essentially panel ground). See Appendix 1 for input connection information. Common mode signals can be removed by signal processing algorithms, instead of the more traditional difference amplifier approach. This greatly simplifies the external analog circuitry, increases the accuracy, and allows measurement of the Neutral-to-Ground voltage at the panel.

  • Page 80: Geometric Va Calculations

    true Watts. The per-element VAs are calculated from the product of the per-element Volts and Amps. The per-element VARs are calculated from fundamental VARs. In any connection type, the Total Watts and Total VARs is the arithmetic sum of the per-element Watts and VARs.

  • Page 82: Compensated Watts And Vars (Line And Transformer Loss Compensation)

    6.7 Compensated Watts and VARs (Line and Transformer Loss Compensation) The total Watt and Var losses can be calculated using five user entered parameters and measured current and voltage values. These losses are added or subtracted to/from the measured Total Watts and Total Vars when accumulating Energy.   ...

  • Page 83: Energy

    B, C, and D. Users who do not intend to use system losses should simply set E equal to zero. A detailed application note on loss compensation in the 50 Series can be found in the documentation library of the Novatech website, www.novatechweb.com. 6.8 Energy Separate values are maintained for both positive and negative Watt-hours, positive and negative VAR-hours, and VA-hours, for each feeder.

  • Page 84: Frequency

    6.9 Frequency The M650 monitors the change in Phase Angle per unit time using the Phase Angle measurement for the fundamental generated by the FFT. The System Frequency is the frequency of the input used for synchronizing the sampling rate. 6.10 Demand Measurements The traditional thermal demand meter displays a value that represents the logarithmic response of a heating element in the instrument driven by the applied signal.

    are set equal to the Present Total Watt, VAR, and VA Demand values. A demand reset does not change the value of the Present Total Watt, VAR, and VA Demands. 6.10.4 Demand Resets The demand values are reset in 3 groups: current, voltage, and power. This can be accomplished via the front display or from a web browser.

    Alternatively, Current Harmonic Distortion can be  measured as Demand Distortion, as defined by IEEE-519/519A. Demand Distortion differs from    traditional Harmonic Distortion in that the denominator of the distortion equation is a fixed value. This fixed Equation 3 - Current TDD denominator value is defined as the average monthly peak demand.

  • Page 88: Fundamental Voltage

    6.11.4 Fundamental Voltage Fundamental Volts are the nominal component (50/60Hz) of the waveform. The M650 measures the magnitude of the fundamental phase-to-neutral and phase-to-phase volts. These measurements can be used in conjunction with the distortion measurements to obtain the magnitudes of harmonics, in other words, convert from percent to volts.

    6.11.7 Phase Angles The M65x measures the Fundamental Phase Angles for all Currents, Line-to-Neutral Voltages, and Line-to-Line Voltages. The Phase Angles are in degrees, and all are referenced to the V Voltage, which places all Phase Angles in a common reference system.

    6.15 Instantaneous Measurement Principles The M650 measures all signals at an effective rate of 64 samples/cycle, accommodating fundamental signal frequencies from 45 to 65Hz depending on model. Samples of all bus signals are taken using a 16-Bit A/D converter, effectively creating 64 "snapshots"...

    APPENDIX A1 CT/VT Connection Diagrams Please note that there is an option on the Settings/Input page to invert the CT Polarity (see screen shot clip below). This option is the equivalent of swapping the connections in the connection diagrams below at the HI and LO terminals for each CT input, that is, swapping 7 and 10, 8 and 11, 9 and 12.
