Rish PQM – Power Quality Monitor
Rish PQM is a compact, multi-function panel mount power quality monitor, which measures, calculates and displays major electrical parameters of three phase power system like Voltage, Current, Active / Fundamental Reactive / Apparent Power and Energy, Individual Harmonics, Sags and Swells.
Description
Features
Measures & Monitors more than 80 parameters
- All basic electrical parameters.
- Power quality parameters (Overcurrent ,Sag & Swell).
- Individual harmonics contains of per phase voltage and current.
True RMS measurement
The instrument measures distorted waveform upto 56th Harmonic for 50Hz and upto 46th Harmonic for 60Hz.
Power Quality Measurement
- Sags & Swells detection
- Measurable up to 56th (50Hz) harmonic on each phase. Maximum any 6 harmonics can be monitored simultaneously for each phase.
- Measurement of RMS value of fundamental and per phase voltage and current harmonics.
- (%) THD of per phase voltage and current
- Distortion factor of individual harmonics.
- Time stamping of sags & swells.
Graphical Analysis
- Per phase individual harmonic bar graph representation.
- Real time vector representation of all 3 Phases for complete system analysis.
Energy class 0.5S as per IEC 62053
- Independent Import and Export energy counter.
