A The Position represents the position where the acquisition module is physically
connected to the RPV311. Positions A to L.
B The Module scroll box allows user to select the acquisition module used in the
link and its characteristics based on the Part Number of the module. The
modules can be:
RA331: Acquisition module with up to 8 analog (voltage, current, or DC) and 32
digital channels;
RA332: Acquisition module with up to 16 analog (voltage, current, or DC) and 32
digital channels;
RA333 (TW): High frequency acquisition module with 3 high-speed analog
channels for acquisition of the traveling waves;
RA333 (DFR): Acquisition module with up to 8 analog (voltage, current, or DC) and
16 digital channels.
C The Fiber length text field allows user to enter the fiber length, in meters, to
compensate the delay in the data transmission between the acquisition and
processing modules.
All analog channels have two configuration options. Circuits and channels will be
configured based on the option selected.
In the Inputs section, shown in
of the acquisition module connected with the RPV311 configured in the previous
section. It is important to configure the analog inputs for voltage or current,
according to the physical configuration of the module, shown in Chapter 15:
Installation. The RA333's high-speed acquisition channels do not require
configuration, since they are dedicated for voltage measurement.
To improve the accuracy of the measurement, a correction factor can be manually
provided. Inputs without the correction factor have accuracy better than 1%.
The digital channels do not have type selection.
Figure 13, it is possible to configure the analog inputs
