Use of Laptop Computer to Facilitate Testing
The functions of Reydisp Evolution can be used during the commissioning tests to assist with test procedures
or to provide documentation for recording the test and test parameters. One method is to clear the event
records before each test is started, after the test upload from the relay, the settings, events file generated as a
result of application of the test. These files can be saved to retain a comprehensive record of that test.
You can prepare the relay settings on the laptop computer (offline) or on the relay before the test. These
settings must be saved for reference and compared with the settings at the end of testing. It enables checking
of errors that are not introduced during testing and any temporary changes to settings to suit the test process
are returned to the required service state.
A copy of the relay settings as a Rich Text Format (.rtf) file suitable for printing or for record purposes can be
produced from Reydisp Evolution as follows:
•
From the File menu, select Save As.
•
Change the File type to Export Default/ Actual Setting (.RTF) and enter a suitable file name.
When testing is completed, the event records must be cleared and the settings file checked to ensure that the
required in-service settings are being applied.
