power qualityfor integration

The iSTAT M355 is a Power Quality Analyser that provides measurements to IEC 61000-4-30 2008 Class A and reports Power Quality compliance to EN50160: 2011. Sampling at a rate of 31 kHz (620 samples per cycle at 50Hz) and true RMS measurement gives accurate readings under all harmonic conditions, with Measurement accuracy better than 0.1% and Class 0.2S Energy. The M355 is also a fully functioning communicating measurement centre, with 4 voltage and 4 current inputs, providing more than 150 measurement quantities and harmonic analysis on current and voltage inputs to the 63rdharmonic. The M355 also includes a Trend data recorder capable of recording up to 128 channels of analogue measurement data and an alarm status recorder. The M355provides all of the power quality measurements required by EN50160 including Flicker (EN61000-4-15) and Harmonics (EN61000-4-7 Class 1) and also calculates interhamonics.
