• Reading of the Hydran 201 i System’s historic data (using the H201T i or the Hydran Host
software): See Section 11.2.2 on page 11-6.
11.2.1 Direct Data Reading
Data can be read directly as follows:
• With the Hydran 201Ti : Its user-interface includes a six-key keypad and a 2-line per
16-character display. For details, see Chapter 4.
• With the Hydran 201Ci-1 : Its user-interface includes two illuminated push-buttons and
a display, all mounted on the enclosure’s door. Note that the H201C i -1 does not provide
the cause of the alarm.
• With the Hydran Host software : A host computer running General Electric Canada’s
Hydran Host software remains the easiest way to read data. The host computer screen
provides an interaction far superior to the one of the H201T
i ’s user-interface. For details,
see the Hydran Host Software Manual . The windows Network Survey and Real Time
Log Set-Up can be used to monitor the data of up to 128 H201T i ’s.
11.2.2 Historic Data Reading
The historic data simply consists of information (self-explanatory message, date and time
of occurrence, etc.) recorded by and within the Hydran 201T
i when an event happens
(alarm triggering, parameter modification by the user, etc.) or at fixed, adjustable logging
rates.
Historic data can be read as follows:
• With the H201Ti : Simply access the History submenu with the H201T i ’s keypad. For
details, see Section 4.5.1 on page 4-12.
• With the Hydran Host software : The H201T i ’s historic data can be accessed easily using
General Electric Canada’s Hydran Host software. Simply transfer the historic data from
the H201T
i ’s toward the Hydran Host software with the Express Download button in
the Network Survey window. The procedure is described in the Hydran Host Software
Manual .
11.3 DATA ANALYSIS
The Hydran 201 i System generates numerous data to assist in the early detection of
incipient faults in transformers or other oil-filled equipment.
