Dran-View’s unique linked two-pane browser allows you to view time plots or phasors and waveforms simultaneously and interactively to quickly diagnose problems.

Compare data from different monitoring points and sites before and after critical events.

Overlay or stack multiple parameters to detect interdependent trends, reveal details, and correlate measured phenomena.

Correlate and graph all parameters of interest in overlaid, stacked, or 3D graphs. change and plot monitored and calculated parameters “on the fly.”

This type of three dimensional graph is useful when there are many parameters to be presented as a function of time.

Dran-View’s multiple zoom levels—up to 15 times—let you zoom out to see a month’s worth of data at a time, or zoom in to see a specific millisecond of an event. Dran-View’s two-pane browser aligns the event with its specific detail for immediate analysis. 

This screen demonstrates a disturbance which is marked with a yellow background.

Using simple wizards, in a matter of seconds, your entire power quality survey will be formatted into a professional report that will allow you to quickly determine what happened and make informed corrective decisions.

Simulate the impact of harmonic generating loads and instantly view the effects of a harmonic filter.

Here is an example of a waveform constructed with the harmonics demo tool driver which enables the user to see how the waveform changes with various levels of harmonics and with different harmonic phase angles. 

Event type, magnitude and duration are automatically classified according to IEEE 1159 standards.

The ultimate in simultaneous parameter viewing. The left pane plots up to 20 parameters and eight channels. The right pane details waveform events and descriptive disturbance analysis text. Either pane can be displayed as full screen. You can always zoom in on any pane for a closer look.

When in Dran-View, simply select Report Writer from the pull-down menu and the Report-Writer Wizard will prepare your report. Customized options such as power quality parameters and flow, as event list, and an analyzer set-up are easily implemented. You preview your report on screen and save it as an RTF file for import into most word processing software programs.

The event list displays all the events recorded by the analyzer and makes it easy to identify the type of disturbance quickly. Channels are color-coded with the time and date stamp. Click on the selected event and the waveform appears instantly in the right pane.

Dran-View accelerates your analysis by presenting a worst case summary report for any monitored parameter and channel for the entire survey period. Zoom in on a selected time range and the report automatically changes to the same period.

Being able to compare before and after data, as well as different monitored locations, is critical to power analysis Dran-View even lets you view data from different Dranetz-BMI analyzers at the same time. 

Changing and plotting monitored parameters on the fly is just one of the ease-of-use features in Dran-View. The Window-type dialog box allows easy point and click selection of any channel or parameter. Plot parameter vs. parameter to see how they compare to each other over the monitoring period. Experience the power of flexible analysis.

Harmonic currents are presented with the Y axis scaled or the best possible resolution.

Use separate graphs to show how the harmonics vary during a dip or sag.

The graph to the right shows a flicker measurement taken over a twenty-four hour period with several different flicker parameters on different axis.

Flicker direction can also be tracked to find the source of the problem.
