SD006-KHA (Harmonics Explorer) ｜アップデート Ver 2.9.0以降

Resolved an issue where reports could not be created correctly for test results files in which the measured voltage of all channels was below 20% of the nominal voltage.

Resolved an issue where graphs were not displayed correctly when loading test results files with a "3P3W" wiring configuration.

Corrected the printing of the flicker limit standard to “IEC61000-3-3 Ed2.0” in reports generated from the test results of the flicker measurement technical standard IEC61000-4-15 Ed1.1.

Updated the threshold values used for “repeatability check” on IEC61000-3-2 Ed5.2 as follows: brbr11th order or lower: The average harmonic current being compared must be within ±(5% of the limit value + 1 mA). brbr12th order or higher: The average harmonic current being compared must be within ±(10% of the limit value + 1 mA).

Applied positive and negative peak voltage judgment (i.e., crest factor judgment) to Classes A and B in “Checking the AC power Source” when IEC61000-3-2 Ed5.2 was selected.

Added a notification that is displayed after the test on IEC61000-3-12 2021 when the following settings and conditions are met: classification of EUT is “Balanced 3-P,” and the limit value is either “Spec Bal’d 3-P” or “Table5 3-P.”

Resolved an issue where duplicate options appeared in the current scale setting of the 2D/3D harmonic graph when loading IEC61000-3-12 files.

Resolved an issue where the displayed values in the 2D/3D harmonic graphs differed from those in the results list when loading IEC61000-3-12 files.

Resolved an issue that prevented reports from being created correctly when specific characters were included in the file names of loaded test results files.

Discontinued tests for harmonic limit standards IEC61000-3-2 Ed5.0 and IEC61000-3-12 2011. Enabled tests for IEC61000-3-2 Ed5.2 and IEC61000-3-12 2021 instead.

Discontinued tests for flicker limit standard IEC61000-3-3 Ed3.1. Enabled tests for IEC61000-3-3 Ed3.2 instead.

Changed to display a prompt for an update if a KHA3000 with an outdated firmware is connected.

Added support for the flicker limit standard IEC 61000-3-3 Ed3.2 with the following features. (Supports the KHA3000 with versions 3.61 and later.) brbr- Updated IEC61000-3-3 Ed3.2 report text: standard name set to “IEC61000-3-3 Ed3.2” and alias set to “EN61000-3-3(2013)/A2(2021).” brbr- Retained support for loading IEC61000-3-3 Ed3.1 test results files.

Added support for the harmonic current limit standard IEC 61000-3-2 Ed5.2 with the following features. (Supports the KHA3000 with versions 3.61 and later.) brbr- Updated IEC61000-3-2 Ed5.2 report text: standard name set to “IEC61000-3-2 Ed5.2” and alias set to “EN IEC 61000-3-2(2019)/A2(2024).” brbr- Changed the current values of each channel printed on reports for IEC61000-3-2 Ed5.2 to the average values during the test period. (The maximum values during the test period were printed on reports for Ed5.0.) brbr- Changed the POHC values of each channel printed on reports for IEC61000-3-2 Ed5.2 to the average values during the test period. (The maximum values during the test period were printed on reports for Ed5.0.) Also added a supplementary explanation about the POHC calculation method at the bottom of the page. brbr- Retained support for loading IEC61000-3-2 Ed5.0 test results files.

Added support for the harmonic current limit standard IEC61000-3-12 2021 with the following features. (Supports the KHA3000 with versions 3.61 and later.) brbr- Updated IEC61000-3-12 2021 report text: standard name set to “IEC61000-3-12 2021” and alias set to “EN61000-3-12(2011)/A1(2024).” brbr- Added report output for conformance against the condition (c) or (f) when the following settings are met: selected standard is IEC61000-3-12 2021, classification of EUT is “Balanced 3-P,” and the limit value is either “Spec Bal’d 3-P” or “Table5 3-P.” brbr- Retained support for loading IEC61000-3-12 2011 test results files.
