2.1 Installation WARNING - INSTALLATION AND MAINTENANCE SHOULD ONLY BE PERFORMED BY PROPERLY TRAINED OR QUALIFIED PERSONNEL. 2.2 Initial Inspection Bitronics instruments are carefully checked and "burned in" at the factory before shipment. Damage can occur however, so please check the instrument for shipping damage as it is unpacked.
Page 34: Overcurrent Protection - Aux Pwr (Universal - High Range Power Supply)
2.4.3 Overcurrent Protection – AUX PWR (Universal - High Range Power Supply) To maintain the safety features of this product an external fuse shall be provided at the AUX PWR supply input and must be connected in series with the ungrounded/non- earthed (hot) side of the supply input terminals prior to installation.
Page 35: Connections & Wiring
3.0 CONNECTIONS & WIRING The connection view of the PPX II is shown in figure 3. See Appendix A1 for detailed wiring diagrams covering the CT/VT measurement inputs. 3.1 Auxiliary Power The PPX II is powered by connections to L1(+) and L2(-). A green LED Power (PWR) indicator is provided on the front panel to indicate that the unit is powered ON.
Page 36: Vt Inputs - Va, Vb, Vc, Vn (See Appendix A1 And Section 1.3)
3.2 VT Inputs – VA, VB, VC, VN (See Appendix A1 and Section 1.3) The PPX II is capable of monitoring two voltage buses, designated as Bus 1 (Terminals 3-6) and Bus 2 (Terminals 7-10). Voltage signals are measured using a 12.06Mohm (12Mohm/60.3Kohm) resistor divider with a continuous voltage rating of 7kV.
Page 37: Network Settings
PPX II is offered with dual standard Ethernet 10/100 Megabit (Mb) RJ45 (copper) interfaces (10BASE-T and 100BASE-TX) which automatically selects the most appropriate operating conditions via auto-negotiation. This interface is capable of operating either as half-duplex (compatible with all Ethernet infrastructure) or full- duplex interfaces (which allow a potential doubling of network traffic).
Page 38 Determining the IP Address if unknown: Bitronics has created a utility program to request the IP address for a specific MAC address on an Ethernet network. This program can be used with the PPX II. The program is available on the company website http://www.novatechweb.com/downloads/inarp/ The program uses the Inverse Address Recognition Protocol to perform the lookup and thus is called inarp.

Page 49: Optional Irig-B Port
3.7 Optional IRIG-B Port The IRIG-B option allows PPX II system time to be regulated by an IRIG-B clock source. If the clock source is synchronized by GPS, PPX II system time can be aligned with other devices with great precision. Unmodulated IRIG-B input allows system time regulation to 1us, IRIG-B 1kHz modulated input allows system time regulation to 1ms.
Page 50: Irig-B Electrical Specifications (Option)
Valid decoded IRIG-B information is passed to the PPX II system time process. The system time process uses the highest precision valid input to regulate system time. There are no configurable parameters for IRIG-B (signal propagation delay will need to be added).

Page 86: Measurements
5.0 MEASUREMENTS Basic measurement quantities are calculated and updated every cycle. 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 87: Voltage Channels
5.3 Voltage Channels The PPX II uses a unique voltage connection method, which is combined with simultaneous sampling to provide an extremely flexible voltage measurement system. All voltage inputs are measured relative to a common reference level (essentially panel ground). See Appendix 1 for input connection information. Because all signals are sampled at the same instant in time, common mode signals can be removed by subtraction of samples in the DSP, instead of the more traditional difference amplifier approach.
Page 88: Power Factor
5.5 Power Factor The per-phase Power Factor measurement is calculated using the "Power Triangle", or the per-phase WATTS divided by the per-phase VAs. The Total PF is similar, but uses the Total WATTS and Total VAs instead. The sign convention for Power Factor is shown in Figure 12.
Page 89 For example, on a system with a lagging load on one phase and an equal leading load on another phase, the Geometric VA result will be reduced relative to a balanced system, but the Total Power Factor will still be "1".

Page 90: Compensated Watts And Vars (Line And Transformer Loss Compensation)
5.7 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. ...

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 PPX II can be found in the documentation library of the Novatech website, www.novatechweb.com. 5.8 Energy Separate values are maintained for both positive and negative Watt-hours, positive and negative VAR-hours, and VA-hours, for each feeder.

reset. All values are reset simultaneously. Refer to the appropriate protocol manual for details. 5.9 Frequency Frequency is calculated every cycle for every input. The PPX II monitors the change in Phase Angle per unit time using the Phase Angle measurement for the fundamental generated by the FFT.

Page 94: Demand Resets
5.10.4 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. 5.10.5 Demand Interval The PPX II uses 900 seconds (15 minutes) as the default demand interval for current. The default for average volts and average power measurements is 60 seconds.

peak demand. By creating a measurement that is based on a fixed value, TDD is a "better" measure of distortion problems. Traditional THD is determined on the ratio of harmonics to the fundamental. While this is acceptable for voltage measurements, where the fundamental only varies slightly, it is ineffective for current measurements since the fundamental varies over a wide range.
Page 96: K-Factor
Fundamental Volts for that phase (which is the denominator), and the result will be the actual RMS magnitude of the selected harmonic. Fundamental Volts and Amps can be used in conjunction to obtain Fundamental VAs, and when used with Displacement Power Factor can yield Fundamental Watts and Fundamental VARs.
Page 97: Slip Frequency (1-Cycle Update)
In addition, the Phase Angle is calculated for the Bus 1 to Bus 2 per-phase Fundamental Voltages and Fundamental Voltage to Fundamental Current. It is the Bus 1 Fundamental Voltage angle minus either the Bus 1 Fundamental Current or Bus 2 Fundamental Voltage angle for a given phase.
