  • Page 52: Tips And Hints

    Fluke 434-II/435-II/437-II Users Manual Tips and Hints The occurrence of Dips (Sags) and Swells may indicate a weak power distribution system. In such a system voltage will change considerably when a big motor or a welding machine is switched on or off. This may cause lights to flicker or even show visible dimming.

  • Page 53: Harmonics

    Note: the number of harmonics is limited to DC and harmonics 1 … 13 for measurements in 400 Hz power systems such as offered in Fluke 437-II. Measurement of Interharmonics is disabled. The phase angle is not displayed. For further information refer to the Specifications in Chapter 27.
  • Page 54 Fluke 434-II/435-II/437-II Users Manual ENTER The Bar Graph display shows the percentage contribution of each of the components related to the full signal. A signal without distortion should show a 1 harmonic (= the fundamental) at 100 % while the others are at zero: in practice this will not occur because there always is a certain amount of distortion resulting in higher harmonics.

Measuring results are based upon the fundamental frequency component (60 Hz, 50 Hz, or 400 Hz in Fluke 437-II) using method of symmetrical components). In a 3-phase power system, the phase shift between voltages and between currents should be close to 120°.

    Fluke 434-II/435-II/437-II Users Manual ENTER Flicker is characterized by: instantaneous flicker Pinst, short term severity Pst (measured over 1 min for fast feedback), short term severity Pst (measured over 10 min) and a long term severity Plt (measured over 2 hours). Also related data such as half cycle rms for voltage (Vrms ½), current (Arms ½) and frequency are measured.

  • Page 89: Tips And Hints

    A measuring period of 2 hours (Plt) is useful when there may be more than one interference source with irregular working cycles and for equipment such as welding machines, and rolling mills. Plt ≤ 1.0 is the limit used in standards like EN15160. 17-3 Fluke-Direct info@Fluke-Direct.ca 1.800.868.7495...

    Transients Introduction Fluke 435-II and 437-II can capture waveforms at high-resolution during a variety of disturbances. The Analyzer will give a snapshot of the voltage and current waveforms at the precise time of the disturbance. This allows you to see the waveforms during dips, swells, interruptions, current swells and transients.
