PowerQPlus
MI 2392
Advanced, handheld, easy to use 3-phase power quality analyser
• PowerQ Plus is a genuine, portable 3phase power quality analyser which
favorably competes with higher priced
instruments and can be easily
implemented in a variety of different
situations.
• PowerQ Plus is due to its small
dimensions and ease of use ideally
suited for routine or complex power
quality assesment in heavy duty
industrial environments.
Standards
Instrument is developed and
manufactured in accordance with
following standards
Safety:
IEC/EN 61010-1
EMC:
IEC/EN 61326-1
Measurements: IEC/EN 50160
• Pre-set logging screens allow on-site
evaluation of all major power quality
parameters (U,I, P, PF, cosφ
, THD,
individual harmonics componets, phase
shifts, etc.).
• Windows compatible PowerQ Link
software package expands a versatility
Target applications
•Power quality assesment and troubleshooting in low voltage electrical systems.
• Balancing phase currents in 3-phase systems.
• Checking power correction equipment performance.
• Harmonics spectrum analysis for selection of harmonic filters.
• Capturing inrush currents e.g. motor's start up currents.
• Voltage deviations recording.
• Consumption recording.
Phase diagram helps at connecting the
instrument on the power network and is
effectively used at indivual phase
conditions assesment.
Main features
• Simultaneous analysis of basic power quality parameters (U,I,P,Q,S, PF)
• Harmonics analysis up to 50th component
• Phase diagram
• Voltage unbalance calculation for 3-phase systems
• On-line scope function
• Lightweight design
• Downloading software package PowerQ Link
PowerQ Plus enables on-screen evaluation
of various pre-set loggers. This is an
example of a logger for U, I and f.
