    The SureStart feature briefly reports its findings in four groups of information. These are:  Identify System – after analyzing all the voltage and current inputs, PowerSight identifies what type of system is connected.  Error Summary – after analyzing connections, the number of possible errors detected is displayed, appearing for one second, each 6 seconds.

  • Page 46: Error Summary

    The bottom line of the display tells the specific voltage type of the general system that has been detected. For instance, a typical display is “277 / 480 V (p-n, p-p)”. This means the nominal voltages present are 277 Vrms phase-neutral and 480 Vrms phase-phase.

Although assuming that the voltage connections are not rotated identifies the phases incorrectly, the total power will be correct and the individual readings will be correct. The phases will be mislabeled. Another thing to consider is that in some cases, several possible explanations for the same error are listed as separate errors.

    A measure that changes continuously is of limited use. A far more useful measurement is RMS current, wherein a single number is generated to describe a continuously varying current. The beauty of RMS current is that in power calculations, it makes a contribution to power roughly equivalent to a DC current of the same magnitude.

    Finally, in measuring high voltages, if you use a high voltage probe, enter the ratio of the probe (for instance, 100 : 1) and record the actual voltage being measured. Using these techniques, you can measure anything with PowerSight.

    Voltage & Current Waveforms Introduction Waveforms are very different from logs and other graphs. A waveform is the most basic direct measurement. It displays the instantaneous levels of voltage and current as they continually vary, as you see on an oscilloscope. All other measurements are derived from them.

New measurements are generated each second that replace old measurements. Old measurements are discarded. These are the “present” values that are displayed as you press various keys.

    This is the act of recording summarizing information once every logging period. With PowerSight, the logging period is set by the user, whereas the measurement updating period is always once per second.

    Setting the Data Logging Period One of the most important settings is the choice of logging period. This is the length of time between the creation of data records. This has no effect on the measurement rate or the sampling rate.
