01 – Can RPV be synchronized by NTP/SNTP?
Yes, however, the frequency of acquisition does not have the same stability provided by IRIG-B signal. In this condition, the equipment internal clock is updated every hour and the SYNC indication on IHM remains off.
02 – What types of IRIG-B signals are accepted by RPV, and its effects on the equipment?
IRIG-B000/001/002 formats are accepted by RPV. IRIG-B signal ensures that the frequency of acquisition of RPV data becomes constant, and keeps the internal clock synchronized.
The equipment is in SYNC mode when the frequency of data acquisition is in accordance with the equipment operating frequency, and the equipment clock is updated.
IRIG-B signal takes precedence over SNTP time server.
If IRIG-B signal has extensions it will provide time information such as date, hours, year, time zone and daylight saving time. However, time zone information and DST can be manually configured through the Web Interface, overlapping the extensions from IRIG-B signal.
03 – How to check the version number of firmware installed in the equipment?
The equipment firmware can be checked in two ways: through the display (IHM) where the machine model and firmware version will appear: “RPV-310-38A00″ for example, or by accessing the area of General Information by communication via the equipment Web Interface.
04 – What to do if the equipment is not showing measurements at analog inputs?
First you must ensure that internal jumpers that define if the analog channel will measure voltage or current are correctly set up on boards. The position of jumper varies in accordance with the conditioning module model used, as described below:
– B260-A1(5A)/ B1(1A):
1 and 2 = Voltage (upper)
2 and 3 = Current (lower)
1 and 2 = 1A (upper)
2 e 3 = 5A (lower)
1 and 2 = 5A (low)
2 and 3 = 115V (up)
Upper – 1A and low – 5A
See Chapter 4, Topic 4.6 – Analog Voltage Inputs, of RPV-311 product manual.
If the jumpers are in the correct position and even then the equipment is still with no signal on the analog channel, the possibility of remains of resin in the jumper should be verified, which need to be scraped to eliminate resin in excess and to improve the contact. If the problem still persists or the module model is not listed above, please contact Reason Technical Support for investigation of the case, and measures to adjust the equipment.
05 – What are the possible ways to configure RPV?
There are two different ways to configure the equipment, which are:
– Through the Web interface. Further details are presented in Chapter 8 of the product manual.
– Using RPVTools software (Conftool). Further details are presented in Chapter 13 of RPV-311 manual.
06 – How to back up the equipment configuration?
Backup of a configuration can be done using RPVTools software. For this it is necessary to follow the procedure below:
1st – Have software and plugin corresponding to firmware of the equipment installed on the PC that will communicate with the equipment;
2nd – Open Conftool using Firefox or Internet Explorer browser;
3rd – Add C:/RPV directory. Right-click on Conftool screen, on Global Settings option, as per the pictures below:
4th- On Conftool screen , click on “Download” and enter the equipment IP;
5th- Name the configuration file and ensure that it is saved on your PC and is available on the home screen of Conftool.
More details on RPVTools can be found in Chapter 13 of RPV-311 manual, available for download at Reason website.
07 – What is plugin, and how to check whether it is or not installed on the PC?
Plugin is an application that adds features to RPVTools main software, and is related to the version of firmware of the equipment. Plugin allows RPVTools to receive and transmit a configuration to the equipment, and to edit the configuration file without being connected to it.
To verify that plugin corresponding to the equipment firmware is installed on the PC you need to access the Windows Control Panel by clicking on Uninstall or change a program, and check if such plugin is shown in the list of installed programs. Plugin should appear as follows: “Coftool Plugin RPV-310-38A00”, in this example plugin of firmware 38A00 corresponds to RPV-310 equipment.
08 – What to do when the alarm LED is on?
If the ALARM indicator is on the equipment can be with any of the following difficulties, and the cause of the alarm can be verified by accessing the equipment “Status” on the Web Interface:
Failed fans – Check and clean air filters.
Battery – Equipment operating without external power supply. Check the supply voltage of the equipment.
Transmission of configuration/ – Normal behavior where the equipment when rebooted remains out of operation for few seconds. The indicator should turn off when the equipment is operating, and no action should be taken.
High Temperature – If the temperature exceeds 50°C, check the status of the fans and cooling of the environment where the equipment is installed.
Internal fault – Equipment is not operational, try to collect the log files (PST) and send them to Reason Technical Support.
09 – How to configure the equipment signaling relays?
RPV-310 communication module contains eight signaling relays. Relay 8 (R15/R16 terminals) is of the type normally closed (NF) and is used to signal equipment failure. This contact opens during normal operation of the equipment and closes if the equipment is turned off or has failed the self-test. Relays 1-7 are normally open type (NA), and can be freely configured by the user using the web configuration interface of the equipment.
To make relay 1 configuration, for example, in the equipment it is necessary to access the configuration area and go to Relays. The image below shows the configuration of 750 and 850 log codes associated with relay 1. In this case when a waveform record or continuous measurement is provided by the equipment, the contact of relay 1 will close and signal the availability of records on a supervisory system, for example.
RPV-311 has 4 electromechanical relays with dry contact. The contact of the first relay is normally closed, and opens when the equipment comes into operation and is not user configurable.
The other three contacts are normally open and can be individually configured by the user using the Web Configuration Interface of the equipment. For information on setting up your equipment, go to Chapter 8 of the product manual.
10 – What ports and protocols should be enabled on the network to ensure the equipment functionalities?
So that all functionalities of the equipment can be accessed and used without restrictions to users it is necessary that the following ports and protocols are released on the Ethernet network:
Port Protocol Use
22 TCP/IP Scan, upload of records, firmware upgrade, remote maintenance
80 TCP/IP Remote access via web
123 UDP SNTP time synchronization
4041 TCP/IP Monitoring of instant values via web
4042 TCP/IP Manual trigger
4713 UDP Diffusion of synchrophasors
6969 UDP RPIV cross-trigger
11 – How to configure the equipment to measure signals at 50 Hz?
RPV features a customization area that can be accessed by typing in the browser address bar the following path: http: //Equipment_IP/Setup/. The user and password to be used are the same of the equipment configuration area (user: admin and password: 1234).
For P910 processing modules (RPV-310) and RPV-311 models, this area can also be accessed on the web interface on “General Information”, “Setup”.
12 – What are log files generated by the equipment and how to download them to your PC?
Log files generated by RPV store important information about the equipment behavior, and through analysis of these files it is possible to check in more detail if the equipment is operating properly. These files are often necessary to analyze a failure situation that may have occurred in the equipment to identify the cause.
“Product Support Tools (PST)” tool was developed in order to facilitate the user to collect log files, when an abnormality is detected in the equipment. When collected, the files should be sent by email to Reason Technical Support for analysis and investigation of the case.
PST tool and procedure for use are available on the area of “Downloads” of the Support at Reason website.
13 – What are the fault location types offered in RPV?
There are 2 types of fault location that can be used in RPV, which are:
– Fault location by traveling waves:
It requires additional hardware acquisition modules: T31/U30 for RPV-310 model and RA333 for RPV-311 model, at the two ends of the line. The most accurate locations are independent of the fault impedance and line impedance as well. It is performed in the center for analysis with Fault Locator software (RPVTools).
– Location using Takagi algorithm (one end):
It is performed inside the equipment, provided that configurations with the parameters and LT length are properly defined in the grouping area of the equipment configuration. The accuracy depends on the fault impedance (which worsens as the impedance increases). This is a limitation common to all one end locators based on phasor algorithms.
14 – How to define remote acquisition modules (RA33X) to be used in RPV-311?
The definition of the links of each RA in RPV-311 should be performed by the equipment web interface by accessing: Equipment> Acquisition>Links.
The column Position indicates the link where the acquisition module was installed.
The column Modules indicates the model of acquisition. And the column Fiber is for informing the length of fiber optic used.
The fields that are part of the Modules column shall be populated in accordance with the part number of each module, and specifications relating to connections on connectors are shown on a label located on the side of RA module.
15 – It is possible to install A160 and B260 into the same slot? In other words, is 160 compatible with 260?
No, the modules are not compatible and should not be installed together. The connection for this type of configuration can cause damage to them.
16 – Is it possible to send to cross-trigger Ethernet between equipment of different models of RPV line?
Yes, the equipment of RPV line (RPV-311, PVR-310 and PVR-350) can exchange Ethernet cross-trigger with each other. Ethernet cross-trigger is the equipment capability to send via network a message “warning” all other equipment connected to the same network that a record has been generated by trigger. In this case, equipment enabled to receive cross-trigger will make the record of quantities being monitored at the same instant of time.
17 – What exactly is the information contained in the files that make up the equipment log file (.zic)?
RPV records are compressed into a .zic file (zipped COMTRADE) containing 5 types of file, which are:
Configuration file (.CFG) – It contains data configuration/setting of quantities measured.
Data file (.DAT) – It contains data measured (in ASCII or Binary format).
Observation file (.HDR) – It contains status and equipment system information at the time of recording; In case a fault takes place, the fault location can be found in this file (calculated by impedance algorithm of the line).
Additional configuration file (.INF) – It contains additional information that can be set by the user; the equipment groupings, as defined in parametrization, are stored in this file.
18 – Does RPV send information via MODBUS when using modem connection?
The modem connection in RPV is performed by the serial port connected to a dial-up modem. Through the established connection it is possible to access the Web Interface for monitoring and/or setup of the equipment. In this case, the MODBUS communication is not possible since it occurs in another network layer not shared by the serial port.
An alternative to modem connection would be to use the Ethernet port connected to a router with 3G modem for remote access to the equipment via web. In this case, theoretically, it is possible to use the MODBUS function since this connection is established over Ethernet port, which is in the same network layer used by MODBUS.
19 – How to download records via web interface?
Steps to download records via web interface (one record at a time):
1st – Access the equipment Web Interface by typing its IP in the standard browser. IP address can be checked on the local interface, which shows the equipment communication configuration/setup.
2nd – Access the session of records you want to download:
Records > Short duration
Records > Long duration
Records > Travelling wave
Records > Continuous measurement
Records > SOE
3rd – In the session of the record chosen, select the timestamp of the record you want to open.
4th – Click on the button.
5th – A dialog box will open. Select the DOWNLOAD option and the record will be copied to the destination folder of the computer.
The record saved can be opened directly with Análise Software (by double-clicking on the record file) or by using any other graphical analysis software. To open the record with other analysis software, it is necessary to decompress the file and open the file with .cfg extension that is in the uncompressed file.
20 – How to configure IP in RPV when it is not in my LAN?
Procedure for configuring IP of RPV:
1st – Access the Local Interface of the equipment, and check the Ethernet port IP address to be used.
2nd – Connect the computer and equipment (into the Ethernet port checked) using a cross-over network cable type.
3rd – Change the computer network configuration (Network and Sharing Center – Access properties of TCP/IP 4 protocol) to an IP in the same network of RPV.
Example: If RPV has the following configuration/setup: IP: 192. 168. 2. 199, Network Mask: 255. 255. 255. 0
The computer should have to be configured/set up for:
IP: 192. 168. 2. xxx (xxx is any number less than 255 and other than 199)
4th – Access the Web Interface by typing the equipment IP in a standard browser.
5th – On the Web Interface, enter the configuration/setup session with user and password (default admin/1234).
6th –Access the Configuration session: Equipment > Communication > Ethernet 1/2.
7th – Change IP, Netmask and Broadcast according to the company specifications for the Ethernet port that will be used for communication via LAN.
8th – Make sure to put the addresses of the two Ethernets ports on necessarily different networks. That is, Ethernet 1 should be on a network and Ethernet 2 on another network.
9th – Transmit the configuration to the equipment.
10th – Connect the equipment to a LAN by Ethernet port configured/set up using a pin-to-pin cable.
11th – Connect your computer to a LAN, returning to the default network configuration/setup, and make the communication test by accessing the equipment by the Web interface on the default browser.
21 – How to configure the receipt of GOOSE messages in RPV?
Procedure for GOOSE configuration in RPV:
1st – Copy SCD or CID files to the directory: c: rpv / gooseconf / resources / Input-files
2nd – Open the GOOSE Configurator software (RPVTools).
3rd – Create a new configuration.
4th – Load an IED file (SCD or CID).
5th – Associate the quantities of IEDs according to the relationship table provided in SE configuration.
6th – Save the configuration to keep a backup.
7th – Transmit the equipment configuration through an Ethernet network using its IP address.
8th – Access the equipment via Web interface and on the configuration session, configure GOOSE inputs as the relationship table used in item 5. Configuration of GOOSE inputs is similar to the configuration/setting of physical digital inputs.
9th – Create limits for GOOSE inputs and enable these limits on desired recorders (short duration, long duration and traveling waves).
10th – Transmit this configuration from the Web Interface to RPV.
11th- It is recommended to back up the final configuration through ConfTool Software.
22 – How to locate a fault by travelling waves (TW)?
To carry out a fault localization follow the steps below:
1st – Install RPVTools (application to be used for fault location is TW Fault Locator);
2nd – Using a notepad, access and open TW configuration file, with .tw extension, which is located in: C:\RPV\faultlocator\conf\powerline.tw
This file is automatically created during installation of RPVTools. If you want to keep the original file, just copy it and rename it according to the line in question (e.g. LTSBSM).
3rd – Once the file is open it is necessary to change the required parameters according to the transmission line, and save it.
4th – To find folders containing the records of faults and traveling waves. The folders containing records should be inside the place where the micro receives the records coming from RPV via Scanner software (that is, inside the folder of records), for example: C: RPV/records/Location,Identifier. Where the location and identifier have been defined in the configuration/setup of each RPV.
5th – After copying the files (folders of records and .tw file) into these specific directories and opening the software it will be possible to view the name of .tw file in the ” Line configuration” field. When selecting this file all records related to each line are shown.
6th – A timestamp of one of the ends of the line should be select , and automatically the record with the same timestamp will be selected for the other end of the line.
7th – When there are two timestamps referring to the same event selected in TW Fault Locator, simply click on the LOCATE button and the location will be shown, where possible, in the interface.
8th – If the location is not possible, the following message will appear: “Unable to locate the fault”. In this case, probably the wave fronts are incompatible or the software could not identify them properly. To locate the fault it will need be necessary to use the graphical tool, available from version 12A00 of RPVTools software, or do the analysis manually using the Reason Análise software.
23 – It is possible to configure .tw file with some coordinates of towers to generate KML file in Google Earth?
Yes, you can. You can configure the file with only a few coordinates of the towers, for example, adding only 1 to each 10 transmission line towers. However, in this case, accuracy of latitude and longitude information of the fault location may be jeopardized. So the ideal is that the coordinates of all line towers are informed.
