If two time intervals are chosen, it will report the percent change and the actual change between the two intervals.
  • Page 57 The instantaneous current is simply the current passing through a point at an instant of time. When the current is graphed over time, the graph is called the current waveform. The peak current, is the highest instantaneous current over a period of time. A measure that changes continuously is of limited use.

    When we speak of a current transient, we are speaking of an instantaneous current that exceeds a trigger level. An absolute trigger level is an instantaneous level that includes the underlying periodic waveform. A relative trigger level is an instantaneous level that has the underlying periodic waveform removed.

    When measuring DC current, the RMS value is the same as the DC value. To set PowerSight for reading DC currents, refer to the section on Setting Measurement Modes. Remember that you need to have a DC current probe (DC2000 or DC600) in order to read DC current.

  • Page 121: Monitoring Swell/Dip/Inrush

    Monitoring Swell/Dip/Inrush Introduction The three general areas of power quality analysis are in investigating on-going harmonic content, analyzing temporary changes in RMS voltage and current levels, and in analyzing instantaneous high-speed (non-RMS) voltage and current transients. Swells (also known as surges), dips (also known as sags), and current inrushes are temporary changes in RMS values that are outside of a norm.

  • Page 122: Swell/Dip Event Log

    If thresholds are set, swell/dip monitoring begins when consumption monitoring begins and continues without interruption. While monitoring is in progress, a green “Monitoring” box is seen at the bottom right corner of the display. It will flash on and off each second to assure you that monitoring is in progress.

    The waveforms can be graphed in order to better understand the swell/dip event. Important information is at the top. The signal name, the timestamp of when the event occurred, the magnitude of the event, and the duration of the event are listed. In addition, moving the cursor over the graph results in the voltage (or current) of that point being displayed in the heading.
  • Page 126 The second type of triggering is Fixed Trigger Level. This is where the user applies the values for voltage and/or current for the meter to trigger on. This is also the only mode that will look for current events as you will manually tell the meter what threshold to trigger on.

  • Page 127: Monitoring High-Speed Transient Events

    It should be noted that you generally will not want to select the neutral current, I , if you are also triggering on other currents. This is because the neutral current is typically much smaller than the other phase currents and needs to have different trigger thresholds.

  • Page 128: Transient Event Log

    There are two types of recordings of high-speed transient events:  Transient Event Logs  Transient Event waveforms. Each of these recordings will be discussed at length in next two sections. The fact that the PS5000 evaluates the high-speed transients every 8 µsecs on every input channel means that no transients lasting more than 8 µsec are missed and precise measurement of their characteristics is available.
