What's new in AMTPro and AMR

What's New

✨ New Features

• A Percent option was added to the Overcurrent Sequence Shot. It works similarly to Factor, but the start, end, and step values are specified as percentages. This is useful, for example, for Negative Sequence testing.
• In Signal View for Overcurrent, Distance, VI Starting, and Differential rooms, signals associated with the selected row's Fault Type are automatically displayed with a thicker line. For example, L1E highlights phase 1, while L2L3 highlights phases 2 and 3. This feature does not modify the user's Signal View settings.
• The Binary Out section in Table View now provides space for at least four rows, and its size adjusts according to the zoom level.
• The Launcher now displays an orange connection-in-progress icon in the Connections table and the main page menu.

🔧 Improvements

• Translation handling was improved. If a form does not have a dedicated translation for a control, a translation from another form is used only when the English texts of both controls match. This prevents unrelated translations from appearing.
• Symbols such as >, =, and & are now displayed correctly in non-English languages instead of appearing as encoded text. Idiff and tdiff symbols are no longer translated, and the Burden labels are now consistent across CT and CVT rooms: Burden @ I test act and Burden @ V test act.
• In Megger and HiPot tests, Binary Input 8 is now set to Not Used in the Test Template, preventing the "Power Supply Connected" setting used by other relays from remaining active in these tests.
• The PMU connection implementation was rewritten. Its Launcher communication settings now follow the AMT connection settings, supporting TCP, UDP, and Serial. The Interface option is available only for UDP.
• PMU Configuration requests are now sent using the configured ID Code. Incoming fragmented frames are reassembled, Disconnect properly closes the connection, and the connection is automatically re-established if it is lost.
• In PMU's 10/100 packet per time mode, all packets received in a batch are now processed instead of handling only single-packet arrivals.
• In Link to XRIO, parameters defined in XRIO in terms of Iref, such as IPICKUP, are now linked using their absolute values (parameter value multiplied by IREF). Existing links in older files are also updated when the files are opened.
• In Overcurrent, each Fault Type's Pickup list now starts with the elements relevant to that fault type: phase elements for phase faults, I2 for I2, IN/I0 for 3I0, and SEF for Sensitive faults. Inom and the remaining elements follow.
• In the Overcurrent Sequence Shot, Simple mode is now labeled X = Ip to clarify that the factors are relative to Ipickup. Total Shot Count is also updated immediately whenever Fault Types or selected X values change, and the number of X values is correctly counted in Simple mode.
• In Signal View, pressing Shift+Y and clicking the horizontal scrollbar track or arrows now immediately adjusts the Y-axis to the new window.
• In Transient Current State mode, Trim Time settings are now applied to Signal View, cursors, and the Characteristic View trajectory, which display only the Start-to-End interval.
• When loading COMTRADE files, frequency is now detected from the signal itself. If the file does not contain frequency information, the detected frequency is used; if it differs from the frequency specified in the file, the user is prompted. The RMS frequency value is also saved in the test file and retained when the file is reopened.
• CSV files in Transient are now loaded using the file's actual sampling rate without rounding sample values, resulting in more accurate waveform rendering.
• For COMTRADE files with current units expressed as xIn, the Primary/Secondary ratio is now retrieved from Device settings to ensure the injected current is calculated correctly.
• In Transient, Primary and Secondary values configured in Device settings are now applied to all channels in the COMTRADE table.
• In Table View, when States are displayed at a small size, pressing Enter moves to the same row in the next State.
• Table View zoom behavior was improved. Excessive zooming out no longer causes a crash, keyboard zoom now uses the same range as mouse zoom (-1 to +4), and title-column rows remain aligned with State rows while zooming.
• In Table View, the selected State now remains synchronized with Signal View when the State is changed in another window while the lower panel is collapsed.
• VCC Firmware update notifications are now handled more consistently. A new notification is not displayed while another is open, and after selecting No, the prompt is not shown again until the next connection. If the Firmware version is incompatible, the test cannot start and the update notification is displayed again.
• The Firmware update process was improved. The Setting window remains responsive, a progress bar and a warning not to perform other operations are displayed, and progress is also shown in the Taskbar. The application prevents other operations until the update is complete.
• Obsolete TesterProg files were removed from the Launcher.

🐞 Bug Fixes

• In Overcurrent Test Object with multiple curves, selecting an element in the table or on its corresponding chart no longer causes the Resulting Characteristic chart to be unnecessarily redrawn or changed.
