Acquisition with remote acquisition modules
The RPV311 data acquisition can be performed by the RA331, RA332 and RA333
remote acquisition modules.
The RA333 module consists of two different acquisition systems. One, called DFR, is
used for analog data acquisition of 50/60 Hz of voltage, current, or DC. The other,
called TW, is used for high-speed acquisition of traveling waves. The RA333 (TW) and
RA333 (DFR) are physically installed in the same module, but are logically
independent, i.e., the RPV311 will be treated as two logical modules.
The RA331, RA332 and RA333 (DFR) modules are independent and use 16-bit opto-
isolated A/D converters with simultaneous acquisition of all channels provided by the
IRIG-B signal, thus ensuring that the frequency acquisition is kept constant.
The analog channels for current measurement use internal shunts to minimize the
effects of phase variation caused by transformers.
There is a delay in the data transmission of the acquisition module for the processing
module proportional to the length of the fiber-optic cable. This delay is compensated
by the RPV311 considering the information of the fiber length specified in the
configuration of the equipment.
The links should be installed of positions A to L. Intermediate empty positions are
considered as "using" 8 analog channels.
Each link must be configured considering the module type and its inputs.
To configure the links, access the L
