Software

The Mehta Tech DFR+ software creates a revolutionary approach to managing your DFR configurations. It lets you easily edit data, compare versions seamlessly, and make a single, comprehensive configuration file for your archival needs.

DFR+ is engineered to provide an intuitive, user-friendly, single-application method for setting up, configuring, or reconfiguring Mehta Tech TRANSCAN DME systems.
DFR+ will alert the user to configuration errors before exporting the configuration to the DFR. This software will not allow a configuration to be exported to the DFR until all errors are corrected.
Provides alerts to ensure proper configuration settings to achieve PRC-028-1 compliance.
DFR+ allows users to navigate freely through the configuration in a single application.
It allows the user to create a “Compare configuration” document to verify current time and date-stamped configurations against past configurations.

TRANSCAN Master Station Software is the user interface that provides customizable system configurations, data communication, SOE Reporting, record format & file conversions, COMTRADE data formatting, and the display and analysis of system behavior.

Easy-to-use master station software is provided to help the user set up the recorder, retrieve records, view and analyze the data. This software is available for the Windows environment. The basic program functions include the following:

Configuration and Calibration
Graphical Display and Printing
Communications between Microprocessor based equipment and local or remote master station computer.

Software Capabilities

Configuration and Calibration Software

This software unlocks the power of the recorder by allowing users to configure independent recorder functions and triggers within each recorder. TRANSCAN recording parameters may be modified by software, either from a local computer or remotely from the Master Station.

Trigger types and levels may be independently set for each channel.

Communication Software

The communication software developed by Mehta Tech allows the user to communicate via modem, Ethernet, or IPCU 2 between a local computer, remote master station, and the DFR in the substation.

Data can include analog values, calculated values, and digital input status.
Data files also include station name, record number, date, and time.

Graphical Display and Printing

After retrieval of stored data, the graphical display program is an invaluable tool in analyzing system disturbances. This software allows eleven user-definable display formats which can be saved for each DFR. The display and analysis software is also the launching point for the various analysis tools.

Optional Analysis Capabilities Software

Mehta Tech has developed a number of optional software tools to help the user to analyze records. These include the following:

Conversion to COMTRADE 1999 or 2013 format
Calculate symmetrical components (Negative, Zero, and Positive Sequences)
Calculate deviation from base frequency
Calculate total harmonics (up to 48th)
Calculate amplitude values of currents and voltages
Calculate real and reactive power
Calculate phase angle
Calculate apparent line impedance
Calculate distance to fault
