Measurement of harmonics Measurement of flicker The MeasurementӔ menu in the screenshot above shows the current measurement as defined inthe SettingsӔ menu for testing harmonics. This screenshot shows a flicker measurement in progress. The 1st, 6th and 10th short time flickervalue P > st is above the permissible value P > st =1 in all three phases. The Remaining timeӔ windowshows the time still required to determine a long time flicker value P > lt . P > lt is calculated as anaverage of the 12 P > st values. >

software for the SYS61K (order no. SYS61K-Soft) can also be obtained separately. However, it can only run with the LMG95 and LMG450 analysers. referenceimpedance is available as1-phase and 3-phase versions. It is designed for a current level of 16 A per phase. The reference impedance can be remote-controlled via the digital outputs of the process signal interfaceӔ of the LMG devices. For measurements of harmonics currents, it is bridged by the built-in switch. It is switched in again for measuring flicker. The In the RP series, arbitrarycurve shapes can be set to a limited extent using the...
