    The listed standards most frequently recommend Subgrouped harmonic. Note Fluke recommends the Subgrouped setting unless there are special circumstances why the other methods are applicable for the required test. A change to this grouping method could lead to inconsistent results when making comparisons of other measurements made at the same or other locations.

  • Page 56 3 Phase Power Quality Analyzer Glossary On polyphase systems, a voltage interruption begins when the voltages of all channels fall below the voltage interruption threshold and ends when the voltage on any one channel is equal to, or greater than, the voltage interruption threshold plus the hysteresis. Note On polyphase systems, the event is still classified as a dip when the voltage of only one or two phases falls below the interruption limit.
  • Page 57 1773/1775/1777 Users Manual An RVC Event is detected when the arithmetic mean of 100/120 U (1/2) values falls outside the an RVC threshold. When a voltage change crosses the dip or swell thresholds, it is considered a dip or swell and not a rapid voltage change. The event list shows the voltage step, transition time, and Vmax.
  • Page 58 3 Phase Power Quality Analyzer Glossary This trigger is a general-purpose trigger that detects non-stationary phenomena and is perfectly suitable for all kinds of disturbance analysis and troubleshooting, because most of the power quality problems result in a sudden change of the waveform. From the recorded waveforms, in most cases the root-cause of distortions can be identified: Switching of capacitor banks, commutation distortions, and oscillations on the mains supply.
  • Page 59  Sample rate 1 MS/s or 20 MS/s  On the Fluke 1777, use 1 MS/s if the subsequent waveform after the event up to 0.5 s is of interest. Note The use of 1 MS/s impacts the accuracy of the peak measurement.
  • Page 60 3 Phase Power Quality Analyzer Glossary Trigger sensitivity  This sets the voltage level of the spectral component of the input signal above 1.5 kHz. Predefined settings of low-medium-high for the trigger level allow an easy configuration based on the required trigger sensitivity, where low is the most sensitive setting. You can configure a custom setting when the session should, for example, store only events >500V.
  • Page 61 1773/1775/1777 Users Manual Inrush Current. Inrush currents are surge currents that occur when a large or low-impedance load comes on line. Normally the current will stabilize after some time when the load has reached normal working condition. For example, the start-up current in induction motors can be 10x the normal working current.
