Oscillographic Analysis Tool
ABB's Oscillographic Analysis Tool enhances the fault analysis capabilities of the ABB 1500R Protection Units. The
Oscillographic Analysis Tool displays the waveform data captured by these units. Besides all analog wave forms, this
program shows digital input/output, pickup, and fault information.
The analog wave forms are displayed simultaneously in individual windows. Each window contains a trigger indicator, a
left cursor, and a right cursor. You can move either cursor to any position within the window for that wave form. When you
move the cursor in one window, it moves in the other windows as well. Each waveform window can be resized to enhance
viewing and can be deleted individually.
The time location of the left and right cursors and the difference in time between the cursors are provided in the Main
Display window. Other information in the Main Display window includes the file name from which the waveform records
were extracted; the date, time, and trigger position of the sample taken at the Protection Unit; the unit ID number; and the
catalog number.
You can overlay an individual analog wave form onto any other analog wave form. For example, you can overlay Va onto
Ia to examine the phase relationship.
You can scale all current wave forms with respect to the largest amplitude within that group. This is called the Actual
Scale and is the default setting. But you can also scale wave forms with respect to the largest amplitude encountered for
that wave form only; this is called the Normalized Scale. The Normalized Scale accentuates noise and other characteristics
of the wave form.
A zoom feature allows you to position the left and right cursors within the wave form and then "zoom in" to closely
examine that section of the wave form.
System Requirements and Installation
The Oscillographic Analysis Tool installs with WinECP. See Section 5, " Interfacing with the Relay" for more information.
Using the Oscillographic Analysis Tool
The Oscillographic Analysis Tool is a menu-driven program. A parent window contains windows for the analog wave forms
and for digital information.
Opening a File
1.
Start the Oscillographics Analysis Tool from the File Menu
in WinECP.
2.
Click on "Continue" at the prompt.
3.
Under the File Menu, select "Load Graph Data File".
4.
The "Open" window appears. Oscillographic Analysis
Tool files are listed as *.CAP files, including the
TEST.CAP file. C lick on the file you want and select
"OK", or double-click on the filename.
The file loads and the individual analog waveform windows appear.
