MEASURING FUNCTIONS
• Voltage: TRMS, peak, crest factor (4-channels) • Current: TRMS, peak, crest factor (4-channels) • Power (active, reactive, apparent) • Power measurements fully compliant with IEEE 1459 (active, non active, fundamental, harmonic, load unbalance) • VFD (variable frequency drive, 5 Hz – 120 Hz), 400 Hz • Unbalance, flicker measurement • Harmonic and interharmonic analysis up to 50th harmonics, THD and TDD measurements • Energy (active, reactive, generated, consumed) • Capturing and recording of power supply events (shutdowns, interruptions, swells, dips) • Inrush currents monitoring and recording • Waveform/inrush displaying, snapshot and recording • Power quality analysis according to EN 50160 • Recording up to 7 adjustable alarms • Temperature measurement • Photo-voltaic inverter efficiency measurements • Power factor, cos fi and tg fi.
