2 Product Scope

The processing unit RPV311 and the acquisition modules RA331, RA332, and RA333
offer a distributed solution for Multifunction Digital Recording. The solution is
designed for the acquisition, monitoring and recording of electrical quantities
normally associated with electrical power generation, transmission or distribution
equipment. It is the solution for applications which require flexibility, allowing
installation of RPV311 Processing Unit in existing panels and the Acquisition Modules
RA331, RA332, and RA333 near to the plant seeing monitored the applications
installation.
The RPV311Solution is a multifunction equipment with fan-less and no rotating part
design. It 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.
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 analogue channels (voltage,
current, or DC transducers) and up to 32 digital channels. The RA332 module allows
data acquisition of up to 16 analogue 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 16 digital
channels, using 16-bit A/D converters providing an acquisition rate of 256 points-per­cycle.

 Pushing or pulling heavy objects
 Using the same muscles repetitively

Plan carefully, identify any possible hazards and determine how best to move the
product. Look at other ways of moving the load to avoid manual handling. Use the
correct lifting techniques and Personal Protective Equipment (PPE) to reduce the risk
of injury.

3.2 Electrical Hazards

Chapter 2 – Safety Information

RPV311

RPV311-TM-EN-7

29

Consult the equipment documentation before installing,
commissioning, or servicing the equipment.

Always use the equipment as specified. Failure to do so will
jeopardise the protection provided by the equipment.

Removal of equipment panels or covers may
expose hazardous live parts. Do not touch until
the electrical power is removed. Take care when
there is unlocked access to the rear of the
equipment.

Isolate the equipment before working on the
terminal strips.

Use a suitable protective barrier for areas with
restricted space, where there is a risk of electric
shock due to exposed terminals.

Disconnect power before disassembling. Disassembly of the
equipment may expose sensitive electronic circuitry. Take
suitable precautions against electrostatic voltage discharge
(ESD) to avoid damage to the equipment.

NEVER look into optical fibres or optical output connections.
Always use optical power meters to determine operation or
signal level.

Testing may leave capacitors charged to dangerous voltage
levels. Discharge capacitors by reducing test voltages to zero
before disconnecting test leads.

If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may
be impaired.

Operate the equipment within the specified electrical and
environmental limits.

Before cleaning the equipment, ensure that no connections are
energised. Use a lint free cloth dampened with clean water.

Integration of the equipment into systems shall not interfere
with its normal functioning.

RPV311

Chapter 2 – Safety Information

30

RPV311-TM-EN-7

The functioning of the device has been certified under the
circumstances described by the standards mentioned in

Chapter 17: Technical Specifications (item Type Tests). Usage of
the equipment in different conditions from the specified in this
manual might affect negatively its normal integrity.

The equipment shall have all their rear connectors attached
even if they are not being used, in order to keep their levels of
ingress protection as high as possible

Never manipulate liquid containers near the equipment even
when it is powered off.

Avoid modification to the wiring of panel when the system is
running.

VT circuits must never be left short circuited.

A high rupture capacity (HRC) fuse type with a maximum
current rating of 10 Amps and a minimum dc rating of 250 V dc
may be used for the auxiliary supply (for example Red Spot type
NIT or TIA). Alternatively a miniature circuit breaker (MCB) of
type C, 10A rating, compliant with IEC 60947-1 and IEC 60947-3
may be used.

Digital input circuits should be protected by a high rupture
capacity NIT or TIA fuse with maximum rating of 10 A, or
equivalent MCB as above. For safety reasons, current
transformer circuits must never be fused. Other circuits should
be appropriately fused to protect the wire used.

Reason devices contain an internal fuse for the power supply
which is only accessed by opening the product. This does not
remove the requirement for external fusing or use of an MCB as
previously mentioned. The ratings of the internal fuses are:

RPV unit: 5 Amp, type T, 250V rating

RA units: 2 Amp, type T, 250V rating

CTs must NOT be fused since open circuiting them may produce
lethal hazardous voltages.

3.3 Fusing Requirements

Chapter 2 – Safety Information

RPV311

RPV311-TM-EN-7

31

Terminals exposed during installation, commissioning
and maintenance may present a hazardous voltage
unless the equipment is electrically isolated.

Tighten M3 clamping screws of heavy duty terminal block
connectors to a nominal torque of 1.0 Nm.
Tighten captive screws of header-type (Euro) terminal blocks
to 0.5 Nm minimum and 0.6 Nm maximum.

Always use insulated crimp terminations for voltage and
current connections.

Always use the correct crimp terminal and tool according to
the wire size.

In order to maintain the equipment’s requirements for

protection against electric shock, other devices connected to
the RPV311 and RA33x shall have protective class equal or
superior to Class I.

Watchdog (self-monitoring) contacts are provided to indicate
the health of the device on some products. We strongly
recommend that you hard wire these contacts into the
substation's automation system, for alarm purposes.

Earth the equipment with the supplied PCT (Protective
Conductor Terminal).

Do not remove the PCT.

The PCT is sometimes used to terminate cable screens.

Always check the PCT’s integrity after adding or removing

such earth connections.

The user is responsible for ensuring the integrity of any
protective conductor connections before carrying out any
other actions.

The PCT connection must have low-inductance and be as
short as possible. For best EMC performance, ground the
unit using a 10 mm (0.4 inch) wide braided grounding strap.

3.4 Equipment Connections

RPV311

Chapter 2 – Safety Information

32

RPV311-TM-EN-7

All connections to the equipment must have a defined
potential. Connections that are pre-wired, but not used,
should be earthed, or connected to a common grouped
potential.

Pay extra attention to diagrams before wiring the
equipment. Always be sure that the connections are correct
before energizing the circuits.

The connections: Console1, Console2, MODEM and Process
bus are non-isolated and for local connection only.

Check voltage rating/polarity (rating label/equipment
documentation).

Check CT circuit rating (rating label) and integrity of
connections.

Check protective fuse or miniature circuit breaker (MCB)
rating.

Check integrity of the PCT connection.

Check voltage and current rating of external wiring,
ensuring it is appropriate for the application.

Do not open the secondary circuit of a live CT
since the high voltage produced may be lethal
to personnel and could damage insulation.
Short the secondary of the line CT before
opening any connections to it.

3.5 Pre-energisation Checklist

3.6 Peripheral Circuitry

Reason devices DO NOT feature any automatic CT shorting feature. Therefore
external shorting of the CTs is mandatory. Check the equipment documentation
and wiring diagrams carefully.

Chapter 2 – Safety Information

RPV311

RPV311-TM-EN-7

33

Where external components such as resistors or voltage
dependent resistors (VDRs) are used, these may present a
risk of electric shock or burns if touched.

Operation of computers and equipment connected to
RPV311 and RA33x under environmental conditions such
as temperature and humidity that exceed the conditions
specified in their respective manuals can cause
malfunctioning or even irreversible damage to them or
the nearby installation.

There might be situations in which the RPV311 and
RA33x are operating within its environmental operational
range, but the computers, equipment connected to them
or nearby equipment are operating outside their
operational range. That situation can cause
malfunctioning and/or irreversible damage to those
devices. In that occasion the communication to the
Reason equipment might be compromised but its
recording, operational and safety capacities will not be
affected.

Take extreme care when using external test blocks
and test plugs such as the MMLG, MMLB and P990,
as hazardous voltages may be exposed. Ensure that
CT shorting links are in place before removing test
plugs, to avoid potentially lethal voltages.

Do not insert or withdraw modules, PCBs or
expansion boards from the equipment while
energized, as this may result in damage to the
equipment. Hazardous live voltages would also be
exposed, endangering personnel.

Internal modules and assemblies can be heavy and
may have sharp edges. Take care when inserting or
removing modules into or out of the IED.

Distributed Multifunction Fault Recorder

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 16­bit 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-per­cycle

1.1 Processing Capability

The RPV311 has 8 link connections to communicate with RA33x acquisition units. As
each acquisition unit has different number of channels and functions, they require
different levels of demand from the RPV311. In order to respect the RPV311
processing capability the number of RA33x that can be connected to the RPV311
obey the following rule:
The RPV311 can process 12 logical slots and each RA demands the following number
of slots.

The user can combine the RA units as long as the logical sum of the slots value of
each RA do not exceed the maximum number of 12.

Note:

Differently from the RA331/332 the RA333 has two link: One for the DFR
functionality and another for the TW functionality.

2.2 Synchronization

If the IRIG-B signal has the CF extensions (IEEE1344), timing information as date, hour,
year, time zone and daylight saving time can be provided by the signal. Time zone
and daylight saving time information can also be manually set via the Web Interface,
overriding the information of the IRIG-B signal.

2.2.1 Time Source

On the screen TIME SOURCE it is possible to configure how the RPV311 will interpret the
time zone of the IRIGB signal and also the IP address of the NTPv2, 3 or 4 server.
The configurable settings are:

A The TIMEZONE defines if time zone information is supplied by the IEEE1344
extensions of the IRIG-B signal, or if it is manually set. This option will allow the

RPV311

Chapter 4 – Configuration

RPV311-TM-EN-7

RPV311 to identify the UTC time using information from the signal or from the
manual configuration of the user:

The time setting that the RPV will use for time stamping is configured on the screen
Internal Clock.

It is possible to configure 30 min time zones.

B The NTP FALLBACK SERVER defines the IP address of the SNTP time server to be used
to provide time synchronism when the IRIG-B is not connected.

2.2.2 Internal Clock

On the screen the internal clock for time stamping the registers and logs is
configured, as well as day light saving configurations.The configurable settings are:

 When Auto (IRIGB with extensions) is selected the RPV311 shall use the

information of time zone sent within the IRIGB signal to recover the UTC
time.

 When Manual is selected the RPV will not consider eventual time zones

within the IRIGB signal, and rather it will use the UTC time zone configured in
the Manual parameter to retrieve the UTC time. This option is used specially
when the IRIGB does not inform the time zone, so the RPV311 cannot
retrieve the UTC time unless we inform the time zone manually.

A The TIMEZONE defines if time zone information is supplied by the IEEE1344
extensions of the IRIG-B signal, or if it is manually set.

 When Auto is selected the RPV311 will use the same local time sent within

 When Manual is selected the RPV311 will use the UTC time (retrieved using

B The DAYLIGHT SAVING TIME defines if time information is supplied by IEEE1344
extensions of the IRIG-B signal, or if it is either manually set or disabled. If it is
manually set, it is possible to choose the date and time of the start and the end of the
DST period.

It is possible to configure 30 min time zones.

2.4 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 opto­isolated 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 LINKS section, shown in Figure 12.

Figure 12: Links between RPV and acquisition modules configuration section

RPV311

Chapter 4 – Configuration

RPV311-TM-EN-7

53

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 Figure 13, it is possible to configure the analog inputs
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.

voltage 115 V, AC current 1 A, AC current 5 A, DC current 0-20 mA or DC voltage ±10
V).

C The ADJUSTMENT text field allows user to enter a correction factor to adjust the
accuracy of the measurement.

2.5 Acquisition with Sampled Values

The RPV311 data acquisition can be performed by Sampled Values data, incoming of
Merging Units. The acquisition is done by connecting the Process Bus Ethernet port to
the Sampled Values generator.
If the acquisition is done by Sampled Values, there is no physical link to configure.
The configuration is performed by Subscription links. Each subscription link contains
data of 4 current (Phases A, B, C and Neutral) and 4 voltage (Phases A, B, C and
Neutral) circuits.
Once a subscription link is created, the RPV311 automatically configures the first
channels as current and the last as voltage, as shown in Figure 86. This is done
because the Merging Units send the Sampled Values package according to the IEC
61850-9-2LE.
The RPV311 processing module can be configured with up to 8 Subscription links.

RPV311

measurement purposes.

H The PACKET LOSS TOLERANCE allow user to insert a package-loss rule.

In the Inputs section, shown in Figure 15, it is possible to configure the analog inputs
of the Sampled Values configured in the previous section. It is important to configure
the analog inputs for voltage or current, according to the Sampled Values messages
received of the monitored Merging Unit.

steady-state and SOE) to be removed.

C The <EXECUTE> button allows user to erase all the records on the list.

For details about the memory capacity of each record type, see Chapter 6: Records.

It is possible to send a record to two different servers. In the configuration interface it
is possible to configure the IP address of each destination server and the type of
record which will be sent. When a new record is generated and the record type is
enabled for auto upload, it is automatically transmitted to the servers.
If at the upload time the server is not available or the network is unreadable, the
record is not retransmitted. In this case, the record will be transmitted only through
the automatic scanning by the server.
The automatic upload of records is a process in which the records are transferred to
the server in advance. To ensure that all the records are stored in the server, it is
necessary that the server perform the scanning process periodically. The records
that have already been transmitted to the server are not retransmitted.
In the section shown in Figure 20, it is possible to automatically upload records to a
preset destination.

parameters are10, 12, 15, 20, 30, and 60 fps; at 50Hz they are 10, 25 and 50Hz.

The data selection is related to the groups configuration (refer to Chapter 4:
Configuration, Section 15 - Groups). Each group can configure a PMU with its specific
data and frequency.
The parameters present on the screen are:
<GROUP> this setting displays all the values related to the selected group that can be
transmitted. Each group has a particular setting for the frequency and rate of
change of frequency related to it.
The <ENABLE> check box allows user to enable data packet transmission.
The <ID> text field allows user to enter a single PMU transmitter ID; the range is of 1
to 65534.
<FREQUENCY> selects the reference frequency of PMU. It is possible to choose which
signal is used to calculate the frequency, namely: Voltage from phases A, B or C,
voltage positive sequence, current from phases A, B or C.
The <PHASORS>, Analog data and Digital data fields contain all the inputs configured
on the equipment. The check box allows user to select the input to evaluate
magnitudes.
The <DESELECT ALL> button allows user to deselect all the magnitudes selected.

17.3 Communication

The RPV311 has two types of operation modes: Commanded; and Spontaneous.
When using the Commanded mode the RPV only transmits data when the client
requests. This mode allows up to 4 destinations of the PMU frame through the UDP
ports.
The ports the RPV311 uses to send synchrophasors are:

In Spontaneous mode the RPV sends the PMU data automatically up to 4 different
socket addresses (IP + port number). All 4 destination configuration can be set as
unicast or multicast transmission.
The parameters of the Communication screen are listed below:
<COMMANDED> Sets the respective streams of data to Commanded mode. When set to
Commanded mode. The RPV311 can send the HDR, CFG2 and CFG3 frames
according to the client’s IED request.
<SPONTANEOUS> Sets the respective streams of data to Spontaneous mode. When in
Spontaneous mode it is also possible to select which CFG frame the PMU will use. The
options are CFG2 and CFG3, at least one of them must be set. Additionally, it is
possible to choose if the HDR frame will be sent.
<UNICAST> Sets the addressing of the respective streams of data to Unicast mode.
This kind of transmission connects to a single IP address and the routing of the
messages though the available Ethernet ports are managed by the RPV system. It is
important that the destination IP and the RPV311 share the same subnetwork
address.
<MULTICAST> Sets the addressing of the respective streams of data to Multicast mode.
This mode required the user to choose which Ethernet interface the RPV shall use to
convey the data.

18 MODBUS

Status, analog and digital data are available in MODBUS registers.
Access to SCADA integration is provided over the Ethernet interface. Up to 8
simultaneous connections are allowed a maximum rate of 60 accesses per second.
For further information about MODBUS, see Chapter 9: MODBUS.
Each register reports 16-bit data. Registers are divided into 3 groups:

B The ANALOG DATA field allows user to select a derived quantity and insert a decimal

correction factor of an analog input.

C The DIGITAL DATA field allows user to select a block of a digital input.

D The <DESELECT ALL> button allows user to deselect all the magnitudes selected.

Note: Whenever MODBUS/DNP3 feature is enabled, the RPV will send both types
of messages. It is not possible to enable just one protocol.

The DNP3 functionality is fully associated with the MODBUS functionality in the
RPV311. To use the DNP3 protocol, it is necessary to insert a configuration key at the
equipment to unlock the MODBUS and DNP3 functionalities. However, it is necessary
to check the HABILITATED option at the web interface and insert analog channels block
or digital channel blocks at MODBUS/DNP3 menu.

Chapter 4 – Configuration

RPV311

RPV311-TM-EN-7

To add binary data to the DNP3 slave database (RPV311), it’s just necessary to add a
digital channel in the equipment’s configuration, as shown at section 6. At the

RPV311 restarting proccess, the DNP3 library reads the configuration archive and
adds digital channels sequentially, associating to an integer number plus an
increment, starting at zero, for each digital channel. GOOSE digital channels are not
added to the DNP3 database.

19.2 DNP3 configuration example

19.2.1 Adding digital channels

First step for digital channel DNP3 database association is to create a digital channel.

For analog channels, the first number associated at the DNP3
database is 5. Numbers 1, 2, 3 and 4 are reserved for equipment
information.

19.2.2 Adding analog channels

The analog data possibilites for the DNP3 communication procol are the same as for
MODBUS. The MODBUS analog data are shown in section 1.3.
To configure the analog data, access the MODBUS/DNP3 menu via web interface.
Analog data are added in a sequential way, like the digital channels, but the starting
number for the analog channels is 5. Numbers 0, 1, 2, 3 and 4 are reserved for
equipment information.

Figure 44 shows the analog channels selected at the MODBUS/DNP3 menu and the

table below it shows the associated number at the DNP3 database for each example
analog channel.
