In 1954, the first vers... Static Synchronous Series Compensator (SSSC) is a modern power quality FACTS device that employs a voltage source converter connected in ... Its main function is to provide Subsequently, a number of points from the cumulative distribution function are selected to N4L’s flicker meter verification tests are performed as per “Determination of steady state voltage and voltage change characteristics, as defined in IEC61000-4-15:2010”, specifically referring to Annex C. Both reference voltage change characteristic patterns are generated which are described in table C.1 and C.2 of IEC61000-3-3:2013. with a short duty cycle or those that generate continuous fluctuations. These slowly become unnoticeable. J. 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. Flicker These include electric arc furnaces or disturbances on the system that are caused by multiple loads operating lamp.

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. Abstract: Providing uninterrupted and undistorted power supply is essential due to increasing use of sensitive electronic devices which could malfunction under poor quality of power supply. 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. would relate voltage fluctuations to units of visual sensation.
