IEC61000 Harmonics and Flicker Analyzer - Compliant, Proven and available with UKAS
The PPA55x1 series precision IEC61000 Harmonics and Flicker analyzer provides a fully compliant test and measurement solution to meet the latest IEC61000 Harmonics and Flicker international test standards. The instrument offers both standalone and software driven test ability, giving the user the option to obtain pass/fail results on the instrument with no requirement for a PC. Alternatively IECSoft can be used, this offers the user an intuitive and highly sophisticated reporting and analysis platform.

If coverage of the IEC61000-4-11 and IEC61000-4-13 immunity test standards is also required, N4L’s EMC Test Systems offer compliance to these standards alongside IEC61000-3-2/3 and IEC61000-3-11/12. Example EMC test system configurations are illustrated in the table below.
IECSoft provides the user with the ability to quickly and easily determine failure modes of any DUT, in the past harmonics and flicker test software has provided reporting with little real time ”in-test” analysis of results. IECSoft bucks the trend and offers an easy to interpret user interface, this includes a sophisticated harmonics real time graph display giving analogue representation of data in order to provide the user with a “feel” for the performance of the DUT throughout a test. This is achieved through a carefully designed user interface, for fluctuating harmonics this includes POHC% of limit representation, colour coded Real Time, Average, Fail Average, Fail Max, STL Exception, POHC Exception bar graphs and individual real time harmonic analysis.
Newtons4th have developed a unique user interface for manual switching tests providing the user with both instantaneous Dmax values and a running average throughout the 24 tests, the software will auto compute limits and results from the data gathered. This reduces test time and give the engineer more time to concentrate on the DUT behaviour and failure investigation should it occur.
All PPA55x1 units are supplied with UKAS ISO17025 certification for Voltage, Current and Power as standard, this is performed at N4L in the UK in our accredited ISO17025 Laboratory.
UKAS ISO17025 IEC61000 Harmonics and Flicker certification is available as an option

ISO17025 Calibration and Verification
Every PPA55x1 Power Analyzer supplied by N4L is provided with both a UKAS Accredited calibration certificate up to 850Hz, as well as a UKAS Traceable calibration certificate up to 2MHz. N4L have developed a number of bespoke power calibrators in order to verify the accuracy of every power analyzer supplied over its entire frequency range, this is surprisingly uncommon within the instrumentation industry. Furthermore, development of an ISO17025 (UKAS) accredited Closed Loop Calorimeter in partnership with Oxford University (UK) has verified the performance of the N4L custom designed power calibration rigs with a very low uncertainty level, providing absolute confidence that the wide band performance of all N4L power analyzers is market leading. N4L also offer an optional ISO17025 UKAS calibration service which covers all aspects of IEC61000-3-2/12 and IEC61000-3-3/11, N4L are currently the only power analyzer manufacturer in the world to offer this level of accreditation for Harmonics and Flicker.§
