Harmonic & Flicker Test System
Harmonic & Flicker 測試系統通常包括一個測試儀器和一個測試裝置。測試儀器用於測量產品產生的諧波和閃爍，而測試裝置用於模擬各種不同的電力網絡情況，以確定產品的性能是否符合相關的標準和規定。
在進行測試時，測試儀器會通過一些測試端口連接到測試產品上，並測量其產生的諧波和閃爍。此外，測試裝置會模擬不同的電力網絡情況，例如電壓不穩定或輸入功率波動等，以確定產品在不同情況下的性能。
Harmonic & Flicker 測試系統的測試結果可以用於確定產品是否符合相關的標準和規定，例如國際電工委員會（IEC）的IEC 61000-3-2標準和IEC 61000-3-3標準。這些標準和規定旨在確保電子產品不會對電力網絡造成不必要的干擾和損害，並保護其他電子產品和設備的正常運行。
總體而言，Harmonic & Flicker 測試系統是一種重要的測試設備，能夠幫助確定產品的電力質量和符合性，並確保其對電力網絡的穩定性和可靠性沒有負面影響。
Fully Compliant IEC61000 EMC Test Systems (IEC61000-3-2, IEC61000-3-3, IEC61000-3-11, IEC61000-3-12, IEC61000-4-11, IEC61000-4-13, IEC61000-4-17, IEC61000-4-29)
N4L’s range of IEC61000 EMC test systems offer a complete turn key solution for EMC immunity testing. The combination of the N4A AC+DC Power Source, PPA55x1 and Impedance Networks, as well as intuitive EMC test software (IECSoft) result in a simple, convenient, compliant test package.
N4L are the only IEC61000 EMC test system manufacturer in the world* with an on site UKAS ISO17025 calibration laboratory offering accreditation to IEC61000-3-2, IEC61000-3-3, IEC61000-4-7 and IEC61000-4-15. Calibration and trace-ability are a vital aspect of any EMC test solution and the coverage provided through N4L’s UKAS Laboratory is comprehensive. N4L’s IEC61000-4-15 calibration procedure is particularly noteworthy as it covers the entire test protocol detailed in Annex C of IEC61000-4-15. It is commonplace for specific parameters within IEC61000-4-15 (d parameters are frequently omitted from calibration procedures) to remain untested during typical flicker calibration due to the difficulty in providing trace-ability for such measurements. All tests within the test protocol of Annex C are included within the scope of accreditation and calibration procedures at N4L.
IECSoft is an integral component of the EMC test package, integrating the various hardware components and displaying the data in a clear manner. As an example of IECSoft’s flexibility, the user is able to send comprehensive test data to external customers or colleagues within the design department. This is useful as design engineers are able to replay Harmonics and Flicker tests in real time, allowing visualization of not only the results of the tests (in report form), but also determination of the devices performance throughout the test. An example of this may be that the final report of an IEC61000-3-2 test results in the EUT(Equipment under test) failing on Harmonic 5, IECSoft can replay the behavior of harmonic 5 throughout the test which can significantly reduce debugging time for the design engineer in the event of such a failed compliance test. In the past EMC test systems would only offer details of the harmonic failure levels in summary form, with an N4L EMC test system no such restrictions apply.
