METREL MI 2792 PowerQ4 Plus Power Quality Analyser
The MI 2792 PowerQ4 Plus is top of the range power quality analyser. With it’s 4 current and 4 voltage channels it is suitable for locating, predicting and troubleshooting of problems in three and in single phase power distribution systems. All 4 current channels have the ability to automatically recognize clamps whose range can be set on the instrument.
MEASURING FUNCTIONS
- Voltage: TRMS, peak, crest factor (4-channel)
- Current: TRMS peak, crest factor (4-channel)
- Power (active, reactive, apparent)
- Power factor, cos ?
- Unbalance, flicker measurement
- Harmonic analysis up to 50th harmonic, THD measurement
- Energy (active, reactive, generated, consumed)
- Power quality analysis according to EN 50160
- Capturing and recording of power susply events (shut-down’s, interruptions, swells, dips)
- Inrush currents monitoring and recording up to 10 adjustable alarms
- Waveform displaying and snapshot
MAIN FEATURES
