15 The Nature of the Problem General PQ Surveys look for any unusual activity, including: Sags Swells Interruptions Transients Thd Harmonics 27 Gathering the Data Power Quality Monitoring Studies use default PQ monitoring settings PV440, PG4400 & PX5, Use the Standard Power Quality Demand, Energy mode 28 14

16 Baseline Data If available, monitoring data at the same location from an earlier time without problems serves as a useful basis for comparison 29 Trouble Logs If the survey was prompted by users experiencing problems, any trouble logs with date, time and nature of problems are valuable tools for narrowing the search in the PQ data 30 15

17 Click the File Open Button, or choose it from the File menu Opening Files Select a file to open from the dialog box Click the Open button If you have a baseline data file, open that too 31 What to Look for in the Data Scan the Events window: Events indicate out of spec power quality, except Timed Events which can often serve as baseline steady state conditions Event Subset allows display of only certain types of events: Sags/swells/interruptions, transients, etc All events displayed in ascending chronological order by default. Event Sort: ascending or descending chronological order, or by event type Groups: by site, type or day 32 16

18 Turning off Journal Events (optional) 4400 & PX5 users frequently use the Power Quality mode, and then want to turn off all the journal triggers in DranView To do so, Select Custom Selection from the event subset pull down menu Uncheck Journal Triggers from the View section Note that this does not turn off Journal Intervals Uncheck Events w/o trigger to turn off timed/trend/journal events 33 Click the Report writer button Select Custom Reports Check one or both worst case summaries items Click Next, Finish Worst Case Summaries Scan report for events that require your attention, and note the date and time of occurrence 34 17

25 Intro to Inrush Reports 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 finished starting up High peak currents can cause circuit breakers to trip unexpectedly. Measuring inrush current can help in setting trip levels Since PQ analyzers simultaneously capture inrush current and voltage trends, you can check voltage stability as large loads come on line 47 Gathering the Data Inrush studies require setting up the PQ monitor to trigger on current 4400 & PX5, Use the Current Inrush monitoring mode / setup template 48 24

26 Gathering the Data, continued Parameter Threshold Settings Parameter RMS Current High Limit RMS pre-trigger capture RMS post-trigger capture Waveform pre-trigger capture Waveform post trigger capture When Amps go out, record Transient Instantaneous Peak Setting ~120% of nominal 4 cycles 200 cycles 4 cycles 200 cycles Fault Amps channels 350% 49 What to look for in the Data Check the peak currents and their duration Use the Cursor for readout of momentary values Check if fuses, circuit breakers, and conductors in the power distribution system can withstand the inrush current during this period Check that phase voltages remain stable 50 25

27 Measure waveform with Delta Tool Click on the Delta button Drag out a bounding box for the whole inrush period, showing peak current and duration The top should be on the peak current and the right side should be where steady-state current usage begins 51 Add Related Data to the Window Consider adding other objects to the graph that clarify the data Click an object to insert from the Object Toolbar Objects automatically pertain to the current event Drag any object to move its location in the window Double click objects to edit properties Take a snapshot with the camera button* Such snapshots make good singlepage reports Save the file in.dv6 format to retain the layout and snapshot you created * = available In Enterprise version only 52 26
