5.8.3 Aborting a Test
Tests in progress can be aborted at any time by clicking on the Stop button. Aborted test data files
will be marked as incomplete.
5.9 Printing Results
The Report button allows you to print both on-screen graphs displays and current and voltage
harmonics test result data to an MS Word document. This provides a test report that displays the
test setup, the Pass or Fail result and a graph of the voltage and current waveform as well as the
worst case values for each of the current harmonics. The Report button is available at the end of
a test run or any time a test is aborted with the Stop button.
Note: The MS Word version supported is Word 9.0 (Word 2000). Older versions of MS Word
may no longer work when upgrading to the latest CTS 3.0.XX software version. In that case, a
newer version of MS Word may have to be installed.
5.10 Harmonics Test Data Files
The CTS 3.0 Software can be configured to log test data to a file. The file format used is
proprietary but can be converted at the end of the test to an ASCII text file with tab delimited fields
for voltage, current, power, peak current and all the current harmonics. This data is recorded in
real-time or three to four times a second.
Longer test times will result in larger test data files and reports. If you increase the test time, make
sure you have sufficient hard disk space available to accommodate these long test files. The rate
at which data is written to disk can be decreased to avoid excessive file sizes. The point at which
the program will reduce the rate of data storage can be set in the configuration. Should a test
failure occur while the CTS 3.0 program is in this reduced data rate recording mode, full rate data
recording resumes for a specified number of acquisition buffers. This always provides detailed
information around the time of the failure. These recording rate settings can be set in the
miscellaneous section of the configuration program.
5.11 Three Phase Testing
Three phase testing is similar to single phase testing described above except that three line
voltages and three line currents are being measured simultaneously and displayed in the CTS 3.0
software GUI.
The three phase mode screens are virtually identical in function and form to the single-phase
screens. The user can view one phase at a time, or all three phases simultaneously.
5.12 Replay Mode
The CTS 3.0 Software can be used to replay previously recorded test data. This replay can be
done on the same test system that was used to record the original data or on an altogether
different PC.
In order to replay a test, the data acquired during the test needs to be saved to a CTS native data
file. If the save data option is not enabled in the additional setup window for Harmonics, there is
no way to replay a test later. The Pass or Fail result of any run on the actual test system PC is
always logged however. If a different PC is used to play back data, the data files have to be
transferred to this PC first. The test data files are stored in the following directory:
C:\Program Files\California Instruments\CTS\Data_files
5.12.1 To play back test on the actual test system PC, proceed as follows:
1. From the Test Menu, select 'Replay an existing test'. This will bring up a table showing all
tests ever run on this system.
