Chapter 3: Hardware Design
This chapter provides information about the hardware design of the products.
1 Hardware Architecture
The RPV311 is a multifunction processing unit and has an acquisition system with 16-
bit A/D D converters that provide an acquisition rate of 256 points-per-cycle
synchronized by the IRIG-B signal.
It has a high processing capability, which allows the acquisition of up to 64 analog
channels and 256 digital channels divided in up to 8 acquisition modules connected
by fiber-optic links. Additionally, it is able to detect IEC 61850 GOOSE messages.
All the registers are stored in a SSD hard disk.
It allows communication through the electrical Ethernet ports and optionally has a
double internal converter for optical Ethernet interfaces.
Monitoring and configuration are performed through a web interface; also, it has a
human-machine interface on the front panel for displaying information. It has a
MODBUS and DNP3 interface for SCADA integration.
The RA331 module allows data acquisition of up to 8 analog channels (voltage,
current, or DC transducers) and up to 32 digital channels. The RA332 module allows
data acquisition of up to 16 analog channels (voltage, current, or DC transducers)
and up to 32 digital channels. Both modules use 16-bit A/D converters providing an
acquisition rate of 256 points-per-cycle.
The RA333 module allows data acquisition of high-speed analog channels (voltage)
for one transmission line. This module allows the scheme to obtain traveling wave
records for fault locating. Additionally, the RA333 module allows data acquisition of
up to 8 analog channels (voltage, current, or DC transducers) and up to 32 digital
channels, using 16-bit A/D converters providing an acquisition rate of 256 points-per-
cycle
