3. For example if the interval is one minute and six significant changes occur within one minute they may all fall into the same interval graph data point They are still reported individually in the significant change report The significant change report provides more detail than the interval graph for these disturbances A key advantage of the significant change report is that only one disturbance per channel can be triggered each second If multiple disturbances occur during a second the worst one is recorded This limits the size of the report making it much easier to analyze while still giving single cycle response If event change detailed disturbance information on a cycle basis is required use the event change report Event change gives much more detail but is more complicated to examine The timestamp of a significant change event can be used to find the same disturbance in the event change report for further analysis For more detail waveform capture can be used if enabled If the disturbance triggers waveform capture the raw waveforms of each voltage and current channel can be displayed Again the significant change timestamp is used to find the waveform in the list of captured waveforms Event Change The event change report provides detailed cycle level information about each voltage disturbance This is the most detailed report available excluding waveform capture An event is triggered when the voltage moves pas

6. smaller than the quickest cycling time of a problem load The most frequent reason to use an interval larger than one minute is to increase the recording time Setting the interval to two minutes doubles the recording time without a serious loss of time resolution Other common settings are five and fifteen minutes used to match metering or billing increments or regulatory time periods The second interval graph setting is the Interval Graph Overwrite mode or wrap around mode as we discussed earlier The best setting for this depends on how the Revolution will be used Some users leave a recorder at a problem site until the customer calls with a power quality complaint The recorder is set to a small interval such as one minute or thirty seconds and interval graph overwrite is enabled Because interval graph overwrite is enabled the interval graphs always have the latest few days of data in memory by discarding the old data The data from the Revolution is then downloaded and has the most recent days of interval graph data in memory no matter how long it was recording This recent data will most likely have the voltage disturbance in it Other users will disable interval graph overwrite and leave a recorder at a problem site where the power quality problem is expected to occur soon The Revolution will record the first few weeks of interval graph data and then it will stop interval graph recording The Revolution can be dow
7. sometimes you need to know something about the disturbance before you can set proper thresholds to capture it Despite these potential pitfalls triggered record types are powerful tools in power line monitoring They are most useful for capturing voltage disturbances and power quality problems The captured events are then presented in a text report Triggered record types include power outage abnormal voltage event change i e event capture significant change and waveform capture Non triggered Record Types The second class of record types is not event driven These record types are always logging data regardless of how interesting important or unimportant the data may be The classic example is a paper stripchart which continuously logs data There are no thresholds to set although there may be a parameter to determine how often to collect data The logged data is usually presented as a graph of data points Although there may be a large amount of data using a graph lets the eye pick out important data Problems such as sags and swells are easy to see in the interval graphs In addition to voltage quality studies these record types are used for finding daily trends in current or power values measuring power factor etc The advantage of not having thresholds to set is that there is no question about what data will be recorded The disadvantage is that sometimes much of the recorded data is unimportant For non power quality dat
8. If the voltage crosses a triggering point for longer than the trigger duration an abnormal voltage event occurs The Revolution is initialized with a list of potential nominal voltages such as 120V 240V etc with low and high voltage thresholds for each The actual nominal is picked by the Revolution during the two minute countdown The average voltage during the countdown is compared to each of the nominal voltages the closest one becomes the nominal voltage for the entire recording session There are five standard nominal voltages in the software setup 120V 208V 240V 277V and 480V and two custom nominal voltages The custom nominal voltages can be set to any voltage It is also possible to enable and disable the standard and custom nominal voltages For example if you want to force the Revolution to use 230V as the nominal the standard nominal voltages should be disabled and both custom nominal voltages set to 230V If the standard nominal voltages were not disabled there would be a chance for the Revolution to pick 240V during the two minute countdown if the line voltage happened to be running closer to 240V than 230V at that time The nominal voltage is chosen by the Revolution separately for each voltage channel There are separate high and low thresholds for each of the seven nominal voltages The applicable thresholds are used once a nominal voltage is selected by the Revolution after the two minute countdown Voltage

10. a capacitor bank would be placed to correct power factor The voltage daily profile is normally used to identify voltage regulation problems or other steady state low high voltage issues The current profile can be used to identify daily trends in load current This is also possible with the apparent power profile Power factor and reactive power profiles can be used to set capacitor bank timers to correct for power factor only when necessary during the day The voltage and current THD profiles show when harmonic distortion is present during the day The more days the Revolution records the better the average created by the profile A recording session that just lasts a single day does not incorporate any daily averaging at all Since a profile starts with all zeros a recording session that does not even last 24 hours will include some 15 minute blocks with the data still zeroed A recording session that does not even last 15 minutes will have all zeroes for a daily profile What the Revolution Records 51 An interval graph can also be used for profiling but that is not ideal The interval graph interval is usually set to an interval faster than 15 minutes a fast interval can show too much information making it hard to form a good average profile Often the interval graph only has enough memory for a week or two limiting the averaging time the daily profiles have no such limit Most importantly the interval graph does not divide
11. a history of the largest and smallest one cycle values for each interval graph as well as a running average At the end of the interval the maximum minimum and average values for that time period are recorded as an interval graph data point For example if the interval is set to one minute a typical setting at the end of each minute the voltage interval graph will record the average root mean square RMS voltage the minimum one cycle RMS voltage and the maximum one cycle RMS voltage all during that minute All of the 3600 cycles that occur during that minute are used to calculate the average and for maximum and minimum What the Revolution Records 45 detection For more information on these calculations please see Calculations at http www powermonitors com support calculations pdf These values are presented to the user as three traces on a graph a maximum a minimum and an average The average trace roughly corresponds to interval graphs as a graph from a paper stripchart recorder The maximum and minimum graphs however are unique Each gives the worst case value for every interval with single cycle measurement resolution RMS Voltage and Current 600 4008 Ka 200 GD wr TAI L 13 Fri 14 Sat 15 Sun 16 Mon 17 Tue 18 Wed 600 400 3 5 D 200 Apr 2007 Figure 17 RMS Voltage and Current Interval Graph When the interval graph data fills the allotted mem

15. just shows the important events and measurements The sifting of data into specific record types accomplishes this task Triggered Record Types Revolution records can be divided into two classes triggered and non triggered Triggered records are event driven These record types are triggered by a combination of triggering logic and adjustable thresholds usually voltage based If a trigger never happens nothing is recorded for that record type As more triggers occur the Revolution collects more data for that record type The advantage of this class is that nothing is recorded unless something happens In the ideal case no problems occur so nothing is recorded and no data analysis is necessary Ifa trigger does occur then the Revolution logs the event for later analysis This is a powerful data reduction tool and can reduce huge amounts of data into a few small records containing all the significant events The disadvantage is that success completely depends on good thresholds and settings A low threshold such as 0 5 may cause the Revolution to log records that are not really worth analyzing What the Revolution Records 43 These extraneous records often hide the few important ones Conversely a higher threshold may cause the recorder to ignore important disturbances Although it is often possible to use regulatory limits or other known standards to set thresholds choosing the proper thresholds can be a problem in itself

18. the next cycle then an additional cycle of waveforms is added In general the waveform capture record continues until waveform capture one cycle after the triggering stops If the voltage is fluctuating wildly the entire waveform capture memory could be filled by a very long waveform capture record If the waveform capture memory is full before the end of the event and the unit is in wrap around mode the Revolution automatically erases cycles of the earliest record to make room for the new data If the unit is not in wrap around mode it will not record any waveforms for events occurring after the waveform capture memory has been filled The waveform data is presented as a graph and a report The report is usually used only if the data will be exported to a spreadsheet Typical Settings and Suggested Uses The default setting for triggering a voltage waveform capture is 3 With this threshold the RMS voltage has to change by at least 3 in a single cycle If the threshold is too tight waveform capture will trigger so often that useless events overwrite the important waveforms You may also choose to trigger a waveform capture using a voltage value rather than a percentage The default trigger setting for the voltage is 5 volts In order to use this simply set the percentage setting for waveform capture higher than the voltage setting For example if you would like the trigger threshold to be 5 volts rather than 3 simply set the percent

20. time Since most loads that start and stop usually run for longer than a minute the start and stop effects such as startup current are easily spotted in the interval graph An example is an air conditioner load a forty minute period of cycling on and off is obvious in the interval graph as twenty data points at one load current then twenty data points at low current all connected by straight lines on the graph The first interval of the high current period will probably have a much larger current maximum than the rest due to the What the Revolution Records 47 starting current of the air conditioner The voltage interval will probably have a dip at the same time The most frequent reason to use an interval smaller than one minute is for large loads that cycle on and off more frequently than one minute For example if an elevator is causing power quality problems and it only takes 10 or 20 seconds to start at one floor and stop at another a one second interval is probably necessary otherwise the entire elevator travel will occur during a single interval In this case the Revolution should not be left to record for days since it will only hold the last few hours of interval graph data The best use in this case is to set the interval graph to one second cycle the load such as the elevator for a while in an attempt to reproduce the problem and then download the data recorded by the Revolution In general the interval should be
