Then PQ Analyze starts with an empty screen. The Main Analysis Window When downloading data from your instrument or you open a measurement data file for evaluation, always start your analysis in the Main Analysis Window.
PQ Analyze Overview The Main Program Window 4 Virtual Instruments On the left side of the Main Analysis Window is a list of buttons representing the so called "Virtual Instruments". Each of them can be regarded as an individual instrument which performs a dedicated function. The idea is to realize a virtual unit based on software, combining different measuring devices in a compact housing. The instrument can thus complete a wide range of measuring tasks at the same time.
1760 Reference Manual The status bar shows useful information about your measurement and your Recorder. On the left side you see the storage location of the data on your PC, on the right side there is information about the connected instrument and the connection status LED (green=connected, red=not connected, yellow=searching the network). Try and click the LED. mainwindowstatusbar.bmp Note The Recorder has to be configured before using the LED indicators and the ONLINE mode.
Chapter 5 Setting up a Measurement The Main Settings Window Note If you are running different software versions on the PC and the Recorder, we recommend that you upgrade your system. It is not possible to configure the Recorder, if the software version on it deviates from that on the PC. The main Settings window is the starting point for the configuration of the measurement campaign. The default values of all settings are taken from the measurement definition template indicated in the title bar (.vdf).
1760 Reference Manual mainsettingswindow.bmp 2. To open an existing template (*.vdf), select File > Open. 3. Change all settings according to your requirements. 4. Save the configuration as a template and/or initialize the measurement. Note For the initial test measurements, we recommend accepting the default values for all settings. Based on the initial results, you can then modify the trigger settings to optimize them.
Setting up a Measurement Hardware Settings 5 hardwaresettings.bmp The Analog section provides fields for selecting the appropriate sensor ranges. The Quantity fields show you which signals the Recorder expects on the 8 input channels (this depends on the selected Input Configuration). The Range setting should only be changed if you want to select a dedicated measurement range. Otherwise it should be left in Auto mode. Most current sensors support two measurement ranges.
1760 Reference Manual Nominal/Limit Values In this set of panels, you have the option to change the nominal values of your power system, the thresholds for event detection, and the limits for statistical evaluation (according to EN50160). Vn - fn – IL Enter the nominal voltage of your power system. Depending on the selected input configuration (see “Hardware Settings”) you can either specify the phase to neutral voltage (Vn) or the phase to phase voltage (Vn ph-ph).
Setting up a Measurement Nominal/Limit Values 5 D-S-I nominalandlimits_dsi.bmp The detection of events (dips, swells, interruptions, rapid voltage changes) is based on half cycle rms values or full cycle rms values updated every half cycle (whatever is configured with the Dips, swells and interruptions based on setting). The thresholds relate to the nominal voltage Vn. Set the thresholds for dips and swells. The hysteresis is recommended in the IEC 61000-4-30 Ed.
1760 Reference Manual V [% Un] d Hysteresis is set to 2% 110% 108% Un 100% 92% 90% d d 3% 1% T hysteresis-e.wmf The figure shows how the duration d of events is determined. The Short / long interruption time threshold is the border between short interruptions (normally <3 min) and long interruptions. Short and long interruptions are listed separately in the event list. Enable Flagging by checking Apply flagging concept.
Setting up a Measurement Nominal/Limit Values 5 EN50160 In this section you set the limits for the statistical evaluation of the voltage measurement. nominalandlimits_en50160.bmp Slow voltage variations are often caused by load variations in the distribution network. Enter the mains frequency limit values for 95 % and for 100 % of the measurement time. The evaluation is based on the 10 min mean values. Fast voltage variations are often caused by load switching in the distribution network.
1760 Reference Manual The maximum permissible number of voltage events (dips, swells, and interruptions) is defined here. This number is used in the EN50160 overview graph to scale the height of the events bar. Unbalance occurs if the 3 phase voltage system is not symmetric (that is, phase angles differ from the nominal 120° or magnitudes of the phase voltages differ from each other). This is the limit for 95 % of the 10 min values during the measurement period. EN50160 hxx nominalandlimits_enhxx.
Setting up a Measurement Nominal/Limit Values 5 difference based on setting. The Minimum rate of change is expressed as % of Vn per second and indicates the velocity of the voltage change. It is calculated by dividing the magnitude of the voltage step between two steady states by the unsteady time (this is the duration from the end of steady state 1 until the begin of steady state 2).
1760 Reference Manual CBEMA In the CBEMA window, users can view and modify the permissible tolerances for the evaluation of events according to CBEMA or ANSI. The limit value graphs have been calculated by CBEMA (Computer and Business Equipment Manufacturers Association); these define the effect of voltage events on equipment, depending on voltage and duration. This feature allows for easy evaluation of expected malfunctions.
Setting up a Measurement Start / Stop 5 Start / Stop In this panel you can specify Start and Stop time for a timed measurement campaign. start_stop.
1760 Reference Manual Memory Management In this panel, you can configure the utilization of the Recorder's memory. For continuous recordings you can predict exactly how much data will be stored per time. For triggered recordings however this is totally unpredictable. The purpose of the memory management is to reserve dedicated memory sizes for dedicated virtual instruments.
Setting up a Measurement Memory Management 5 Note The size of the selected memory must match the actual card installed in your Recorder; otherwise wrong information will be displayed in the memory management dialog. memorymanagementsettings.
1760 Reference Manual Recording Modes In this window, you can define the recording time, pre triggers, and hold off time for all the virtual measuring instruments. recordingmodes.bmp The meaning of the parameters can be seen in the graphic on the top of the panel. The picture changes dynamically depending on the settings and is always related to the virtual instrument that has the focus.
Setting up a Measurement Trigger Settings 5 Trigger Settings In contrast to the continuous measurements, which are always recorded, the so-called triggered recordings are only stored when the respective trigger is activated and the trigger threshold is exceeded. For every virtual instrument which is a triggered recording type a trigger settings panel is provided. These are: 1. RMS 2. Oscilloscope 3. Transient 4. Ripple Control Signal 5. Harmonics 6. Interharmonics 7.
1760 Reference Manual RMS triggersettingsrms.bmp This trigger can be applied to phase voltages (V), currents (I), phase to phase voltages (Vp-p), frequency (f), and active power (P) values. This is a trigger on fast rms values (10 ms up to 3 s aggregations). The trigger fires if the measurement values exceed the limits. Select the recordings you want to trigger with the RMS and Oscilloscope check-boxes. rms-oscilloscope.
Setting up a Measurement Trigger Settings 5 Detection of voltage dips- The concurrent recording of voltage and current values provides data to judge whether load variations in the installation caused the voltage dip or if the voltage drops were delivered from other branches of the distribution network.
1760 Reference Manual These triggers can be applied to phase and Neutral voltages (V), and phase and Neutral currents (I). Max and Wave triggers can also be applied to phase to phase voltages (Vpp). The graphic on the top of the panel illustrates the meaning of the triggers. Select the recordings you want to trigger with the RMS and Oscilloscope check-boxes. Five types of different oscilloscope triggers are available: Level, Sine, Max, Phase, and Wave.
Setting up a Measurement Trigger Settings 5 Transient triggersettingstransi.bmp Transients are short, unexpected signals in the distribution network which occur only once and have high amplitude and high slew rate. They contain high frequency components. This is why the input signal has to pass a 1.5 kHz high-pass filter before it is fed into the trigger logic.
1760 Reference Manual Ripple Control Signal triggersettingsripple.bmp This trigger can be applied to phase voltages, to the Neutral voltage, to phase currents and to the Neutral current. The trigger applies to signals at the given Center Frequency. The 50/60 Hz frequency components are attenuated to less than 1 %.
Setting up a Measurement Trigger Settings 5 Harmonics triggersettingsharmonics.bmp Harmonics are signal components with frequencies that are integer multiples of the fundamental frequency. This trigger can be applied to voltages, currents, neutral line voltages and neutral line currents. The values can be given absolutely in V or A, or relative to the fundamental. The setting panel features a limit value editor for the quick and easy adjustment of all limits.
1760 Reference Manual Interharmonics The interharmonic frequency bands are located in between the harmonic frequencies. In these frequency bands you will typically find disturbances like signalling voltages or other sources with frequencies independent from the mains frequency. triggersettingsinterharmonics1.bmp You can trigger on Interharmonics voltages, currents, neutral line voltages and neutral line currents. Interharmonics limits can only be specified as absolute values (V or A).
Setting up a Measurement Trigger Settings 5 Time triggersettingstime.bmp The time trigger allows for the recording of selected measurement values at preset time intervals, at a certain clock time. The following options are available: • Start time of the time-triggered recording (the default value is the next full minute to the actual PC-time) • Repetition time in seconds Note If no repetition time is specified the time trigger generates only one entry in the event list.
1760 Reference Manual ALARM Configuration Digital Alarm Outputs can be set from trigger events and reset by timeout and/or digital inputs (for Topas 1000, alarm setup is still selected from Service menu – it is a device setting there). Both open the General Alarm Configuration panel: alarmconfig.bmp Check the Invert box to invert the logic of the Alarm output channel. Normally the outputs are reset by digital inputs (output channels 1 and 2 by input channel 1, output channels 3 and 4 by input channel 2).
Setting up a Measurement ALARM Configuration 5 allows the detailed events selection per output: alarmout.bmp Click and drag the mouse to select a multi row/column region. Delete clears the entire matrix. Locked and enabled cells change with the selected connection scheme (U/I, U/U, Aron, etc.) Also see connection details in “Functional Description” in Chapter 1 of the User Manual for pin assignment.
1760 Reference Manual Auto-Trigger The Auto-Trigger function is used in situations where exact trigger levels cannot easily be determined. The trigger engine automatically adapts to the measurement signal. Open the main settings window and check Auto. at1.bmp When Auto is checked, only recording parameters for Ripple Control and Free Interval can be changed in Recording Modes. For the other measurement functions informational parameter values are shown: recordingmodesat.
Setting up a Measurement Auto-Trigger 5 When Auto-Trigger is selected all Recording Modes settings are pre-configured with the fixed values below. Table 5-1. Pre-configured Recording Modes Virtual Instrument Aggregation Pre-Trigger Recording time Holdoff time RMS 10/20 ms1 sliding 0.5 sec 5 sec 10 sec Harmonics 200 ms 2 sec 15 sec 10 sec Oscilloscope Sample 0.1 sec 0.2 sec 3 sec Transients 500 kHz 11.08 msec 32.
1760 Reference Manual The following triggers are enabled in Auto mode: Table 5-2.
Setting up a Measurement Auto-Trigger 5 nlv.bmp Example: In the panel above, the Slow Voltage Variations 95 % positive limit is set to 110 %. This means Unom + 10 %. The derived initial trigger setting for RMS voltage upper limit is Unom + 5 % (50 % of the EN50160 setting).
1760 Reference Manual nlv1.bmp Working with Templates The software comes with a number of templates in the form of .vdf files, which have been preconfigured for certain applications. These files are stored in the configuration Templates folder on your PQ Analyze CD-ROM. If you wish to use these templates frequently, copy them into the PQ Analyze subdirectory of your Directory (see “Installation Paths” in Chapter 2): |PQAnalyze|vdf| The general templates (*.
Setting up a Measurement Working with Templates 5 Harmon.vdf Template This template contains the limit values according to EN 50160. A recording is started, if a limit value for voltage is exceeded. The system thereby monitors the 25 harmonics of the voltage and records 3-sec values. These trigger settings thus register any exceeding of the limit values of the voltage harmonics. PC.
