Megger MPQ1000 handheld 3-phase power quality analyzer

Handheld power quality analyzer from Megger is IEC61000-4-30 Class A compliant

Megger proposes the MPQ1000 3-phase power quality analyzer. This handheld analyzer is IEC61000-4-30 Class A compliant and is rated CATIV at 600V. It can be used, according to Megger, for applications such as substation monitoring, equipment and breaker tripping, load studies and load balancing as well as for switchgear and component failure.

In both the scope and DMM modes, the MPQ1000 can record power, energy, RMS, sags, swells, transients down to 1 microsecond, harmonics, inter-harmonics, harmonic direction, THD, TDD, flicker, unbalance, rapid voltage change (RVC), mains signaling, phase angle deviation, as well as performs waveform analysis to the 128th harmonic in real time.

Data gathered during testing can be recorded with the MPQ1000 record verification by simply pushing a button. This feature automatically detects the current clamps, recognizes its range, identifies the nominal voltage and sets the triggers, as well as verifies that the unit is connected properly to what it is testing.

The MPQ1000 features on board data analysis. An SD card is used to expand memory and all data recorded can be viewed on the unit’s color VGA display, or can be transferred to Megger’s power quality analysis software via USB cable, USB stick, Ethernet or directly from the SD card.
