Features Of Fluke 434/435 Introduction The Analyzer offers an extensive and powerful set of measurements to check power distribution systems. Some give a general impression of power system performance. Others are used to investigate specific details. This chapter gives an overview on how to perform measurements in a logical order. The measuring modes are described in detail in Chapter 7 to 18. Each measuring mode is explained in a separate chapter. Fluke 435 has additional features such as Mains Signaling, Logging, 0.1 % voltage input accuracy acc. to IEC61000-4-30 2003 Class A, extra memory to store Logging Data, Power Log Software, flexible current clamps, and a heavy duty trolley style case. In Fluke 434 the functions Mains Signaling and Logging can be installed optionally. If not installed, they show up in the menu in grey color. General Measurements To check if voltage leads and current clamps are connected correctly, use Scope Waveform and Scope Phasor. The clamps are marked with an arrow to facilitate proper signal polarity. Chapter 6 Input Connections explains how to make connections. To get a general impression of the quality of a power system use MONITOR. The MONITOR key displays a screen with Bar Graphs that show quality aspects of the phase voltages. A Bar Graph changes from green to red if the related aspect does not meet the limits. Up to 7 different sets of limits can be chosen for Fluke 435: a number of them are user programmable. One of these sets are the limits according to the EN50160 norm. For each quality aspect submenus with detailed information are attainable via the function keys F1 ... F5. Numerical data is shown by Volts/Amps/Hertz. For this press the MENU key. Then select Volts/Amps/Hertz and press F5 – OK to display a Meter screen with the present values of voltages (rms and peak), currents (rms and peak), frequency and Crest Factors per phase. Press F5 – TREND so display the course over time of these values. Measuringmodes to investigate details Phase voltages. Should be close to the nominal value. Voltage waveforms must be a sine wave that is smooth and free from distortion. Use Scope Waveform to check the waveform shape. Use Dips & Swells to record sudden voltage changes. Use Transients mode to capture voltage anomalies. Phase currents. Use Volts/Amps/Hertz and Dips & Swells to check current/voltage relations. Use Inrush Current to record sudden current increases like motor inrush. Crest Factor. A CF of 1.8 or higher means high waveform distortion. Use Scope Waveform to see waveform distortion. Use Harmonics mode to identify harmonics and THD (Total Harmonic Distortion). Harmonics. Use Harmonics mode to check for voltage and current harmonics and THD per phase. Use Trend to record harmonics over time. Flicker. Use Flicker to check short and long term voltage flicker and related data per phase. Use Trend to record these values over time. Dips & Swells. Use Dips & Swells to record sudden voltage changes as short as half a cycle. Frequency. Should be close to nominal value. Frequency is normally very stable. Select Volts/Amps/Hertz to display frequency. The course of frequency over time is recorded in the Trend screen. Unbalance. Each phase voltage should not differ more than 1 % from the average of the three. Current unbalance should not exceed 10 %. Use Scope Phasor or Unbalance mode to investigate unbalances. Mains Signaling. Can be used to analyze the level of remote control signals that often are present on power distribution systems. Logger. Allows you to store multiple readings with high resolution in a long memory.
