Networking (23)12. Security (23)IntroductionTRANSCONNECT is the PC software used with the TRANSFIX family of Transformer Gas Analysers, including TAPTRANS, MULTITRANS and MINITRANS. These will be referred to as “analyser” in this document.NB There will be slight screenshot/functionality deviations depending on the connected analyser. TRANSCONNECT is used to connect to the analyser and:Change basic analyser settings such as Gas Alarm Set points and Analysis Intervals.Monitor the status of the analyser and reset Alarm outputs.Download measurement data from the analyser.View and analyse downloaded analyser data and settings offline.Export measurement data for use with other analysis tools.Software InstallationTRANSCONNECT is included in the PERCEPTION installation.In order to run TRANSCONNECT, it is necessary to have Microsoft .NET Framework Version 2.0 Redistributable Package Beta 2 (x86) installed on the computer. This is available from:/downloads/details.aspx?FamilyID=7ABD8C8F-287E-4C7E-9A4A-A4ECFF40FC8E&displaylang=enUSB Driver InstallationThe USB driver will need to be installed separately. This is done the first time the PC is connected to an analyser via USB.Connect analyser to a USB port on the PC. If already connected then please disconnect from the analyser, wait for about 20 sec. and then reconnect. This will launch the Windows Found New Hardware Wizard. The screen below may be shown. Select “No, not this time” from the options available and then click “Next” to proceed with the installation.Select “Install from a list or specific location (Advanced)” and then click “Next”.Select “Search for the best driver in these locations” and enter the USB folder path in the combo-box (“C:\Progam Files\Kelman Ltd\Perception\TransConnect\USB”) or browse to it by clicking the browse button. Once the folder path has been entered in the box, click next to proceed. The USB folder path can be different than shown here if Windows is not installed on the C: drive or you are using another language versions of Windows than English.Windows should then display a message indicating that the installation was successful. Click “Finish” to complete the installation.The analyser USB connection is now ready for use.Getting Started GuideThis quick guide shows you how to connect to a new site and how to retrieve status, settings and data from the analyser.1. PreparationsBefore using TRANSCONNECT for the first time you need to decide how to connect to the analyser and ensure you have the right cables, modem or RS232 Device Servers at hand. Using TRANSCONNECT via a USBconnection requires that you have installed the USB drivers on your computer as above.2. Set up a new siteTRANSCONNECT is invoked from the Perception program. Open Perception and select File / Transfer Data / Load TransConnect.3. Set up CommunicationThis opens the TRANSCONNECT Communication settings window.This window will list any saved connections to analysers, and also detect any analysers that are connected to the computer. New connections can also be added manually using the “New Connection...” button. This opens the New Connection Wizard.Local connections via USB will only be shown if the USB cable is connected to the analyser. USB connections will be automatically detected and added to the list.Click “Next” and choose the method of communication.Complete the settings for the connection.For serial connection, add the COM port, Baud rate, Parity and Flow Control.port number.For modem connection, select the modem to be used.Add the phone number, including any necessary prefix and country code.For all connections, add the password for the device. The password can be stored with the connection details (check “Remember Password”).Phone numberThe final screen will allow the user to check the connection parameters and change the connection name. It is possible to connect immediately by clicking on “Connect”, or to save the connection by clicking on “Finish”. The new conection will appear in the Connections screen.For saved connections, the parameters can be modified by highlighting the connection and clocking on “Properties”:Select the appropriate parameter on the right hand side to modify the settings.4. Main WindowWhen the “Connect” button is clicked, TRANSCONNECT show the connection progress in the window. For local connections and saved connections where the password has not been saved, the password will be requested. If TRANSCONNECT succeeds in establishing the connection to the analyser then the analyser Main window will be shown.This window mimics the analyser unit and shows the status of the lights and the measurement status. From this screen it is possible to start or stop the measurements, and reset the relays or LED’s.The user can also enter their own identification for the analyser in the ID box .The oil sources for the analyser are also shown on the main screen, with the date and time for the next scheduled measurement. The maximum number of oil sources for each analyser type are:MULTITRANS 3TAPTRANS 3TRANSFIX 1MINITRANS 1If the analyser is measuring a sample then the MEASURING message with the measurement start date and time will be shown. This means that the analyser will probably have an oil sample in its sampling cell and is in the process of extracting and measuring the dissolved gases. In this condition you should never stop the measurement unless absolutely necessary. If the analyser is not measuring then the Standby message will be displayed. In this condition it is safe to disable the periodicsample runs. If the analyser automatic scheduling is not enabled, then Scheduler disabled will be shown.To download the latest measurements and settings, click "Download Measurements". TRANSCONNECT will interrogate the analyser and all analyser settings and measurement data will be downloaded to the PC. The download progress will be shown in the window.All the measurement and settings data held in the analyser internal memory can be downloaded into the computer. If the equipment already exists in the Perception database, only new data will be downloaded. If the equipment does not exist in the Perception database, a new Site, Localization and Equipment will be automatically created and the data will be downloaded into the equipment. The analyser will then be associated with the datafile for that Equipment. See Perception User Guide for more details.The “Refresh” button will update the data on the screen. “Apply” is used to apply any changes made – changes will not be saved unless this button is clicked.To disconnect from the analyser click "Exit".5. MeasurementsThe measurements tab contains the results from the last measurement for each individual oil circuit.6. SchedulingThe scheduling tab allows the user to input Normal, Caution and Alarm mode measurements in intervals between 1 hour and 24 hours. The settings can be changed using the drop-down boxes and the “Apply” button.The “S cheduler Enable” box should be checked for scheduled measurements to continue.For analysers with multiple oil circuits, the measurement intervals for each circuit are set independently of each other. In the event that the measurements are scheduled at the same time, the analyser will prioritise the oil circuits.7. AlarmsThe alarm settings for each individual oil circuit are organized in six pages that can trigger alerts based on gas levels (ppm) of the measured gases and rate of change of each measured gas (ppm/day). Each page has its own independent mapping to the available "Alerts".The analyser has a number of alert options:Relays These are dry contact relay outputs ("Alarm Relays") available on the terminal block within the analyser.Caution and Alarm Indicators. These are the bright yellow and red LED indicators on the front panel of the analyser.Caution mode and Alarm mode. Caution mode and Alarm mode designate two states of the analyser for which the measurement intervals can be set up individually. If no alarm condition exists then the analyser will be in "Normal mode". The corresponding measurement intervals are defined in the analyser Scheduling window. Typically Normal mode would use modest measurement frequency while when in Caution or Alarm mode the measurement frequency can be increased in order to closely monitor the situation in the transformer. Recommended TRANSFIX settings are 4 hours for Normal, 2 hours for Caution and 1 hour for Alarm. For analysers with more than one oil circuit, the Normal and Caution intervals can be increased to avoid conflict.SMS. An SMS message can be sent to a GSM cell phone if a GSM cell modem is installed within the analyser. This option requires the GSM cell phone number to be defined in the analyser Settings window.When an alarm is triggered the mapped "alerts" are activated and remain active untilthe alarm condition is no longer met; the earliest this can happen automatically is after the next oil sample has been analyzed. It is possible to manually reset the relays and indicators using the Status window.Each oil circuit has the facility to set up to six independent alarm screens based on discrete concentration levels or rate-of-change of concentration for each of the measured parameters.The rate of change (ROC) in ppm/day is calculated as the slope of the linear regression line through the (time, ppm) data points. The number of data points to be used for each ROC calculation depends on the number of hours set in the Time Window box. A time window between 1 and 96 hours can be defined.A ROC value calculated from only a few data points has a large variance. To avoid an uncertain ROC value from triggering an alarm it is possible to set the minimum number of samples to be used in the ROC calculation. If for some reason the analyser has recorded less valid samples in the “Time Window”than the set “Minimum Samples” then the ROC calculation will not be completed.Setting a large time window means that many “old” measurements are contributing to the slope calculation meaning a slow response time, and there is a risk that changes in ppm values will not be detected. The right number of hours to set for the “Time Window”is a compromise between the wish to have a fast response to sudden changes and the wish to have a robust detection of the rate change, not disturbed by minor random variations in the ppm values. The formula used for the ROC calculation is:where (n) is the number of valid data points available in the time window and (t i,p i) are the (time, ppm) data points.8. InputsIf analogue inputs have been enabled for the analyser, the name and units of the analogue input can be added in the Inputs screen, along with the zero offset and multiplier or the CT ratio. The instantaneous value of the analogue input is shown.9. SettingsThe settings tab allows the user set the normalisation temperature, clock settings and oil source name.The normalisation temperature for the measurements is usually 20°C.The analyser can also be synchronised with the PC clock and the time zone set. The analyser will automatically adjust for Daylight Saving changes in the set time zone if the box is checked.If there are multiple oil circuits, each oil source can be given a name for identification of the results.The settings tab will also permit the user to input numbers and settings for SMS alerts (see Alarms above).10. CommunicationsThe settings for the communications options can be set up or changed in the Communications tab using the drop-down menus and input boxes. Please refer to the communications option user guide for more details.11. NetworkingSettings for networking can be set up or changed in the Networking tab. Please refer to the communications option user guide for more details.12. SecurityThe analyser can be password-protected for security on both serial channels and Ethernet connection. Click on “Set Password” and input the required password.USB direct connection is not password-protected.The policy for accepting or rejecting connection by dial-up modem, Ethernet or GPRS can also be set using the Accept/Reject buttons. Exceptions to the default can be added using “Edit Exceptions”.。
