PQE Power Quality Analyzer (G4500 Series)

PQE Power Quality Analyzer (G4500 Series) Portable Power Quality Analyzer Power Quality Analyzer Power Quality Measurement Solutions

The PQE Power Quality Analyzer G4500 series takes PQ analyzers & power monitoring to a whole new level by using the revolutionary PQZIP patent algorithm. The unique algorithm enables you to measure, store & analyze (continuously) waveform signals regardless their size.


PQZIP inside

  • Continuous waveform recording
  • Trigger free setup
  • 5,000 power parameters @ 1/2 cycle resolution
  • Easy deployment 

Class A
Far surpassing the highest standards set by the industry, the BLACKBOX device series complies with standards for: aggregations, time clock uncertainty, flagging, and transient influence quantities.
Superior Accuracy
PQE’s pioneering measurement method utilizes a dual-range gain of 2 x 16 Bit to yield, a superior accuracy far surpassing IEC 61000-4-30 Class A requirements, thereby capturing the finest details & deviations in Power Quality parameters.
Synchronized Monitoring
A unique time synchronization algorithm assures that logged data from multiple units is synchronized & displayed on the same time scale with typical 0.1 ms resolution. Every event on a grid is accurately analyzed for precise root cause analysis, behaviour propagation, and traced to its source

  • Continuous waveform recording
  • Trigger free setup
  • 5,000 power parameters @ 1/2 cycle resolution
  • Easy deployment

Continuous Waveform Recordings


PQE Power Quality Analyzer G4500 series is able to record and store all electrical waveform continuously for more than a year, with no gaps in the data. The PQE power quality analyzer offers a clear and comprehensive picture of the conditions before, during, and after an event.


PQE Power Quality Analyzer G4500 series meter measures and records 5,000 power parameters continuously at a resolution of ½ cycles, 10/12 cycles, 150/180 cycles, 10 min and 2 hours of which, any given resolution is calculated for display and reporting purposes. Hence, there is no need to select which parameters to log, and more importantly, which parameters to ignore.


PQE Power Quality Analyzer G4500 series has two FFT engines for harmonics analysis: Cycle by Cycle: performs FFT at 1 cycle resolution for extended bandwidth. This engine provides 512 harmonics order at 50Hz resolution. 10/12 Cycles: performs FFT 10/12 cycles resolution for extended resolution and sub-grouping calculation. This engine provides the magnitude and angle of 512 spectrum components at 5Hz resolution.


PQE Power Quality Analyzer G4500 series is designed to detect any event occurring on your system. The mechanism allows you to configure events on any measured parameter (more than 1,000) and/or I/O ports. The event mechanism supports out-of-limit events as well as rate of changed limits. The PQ analyzer is capable of recording waveform signals continuously. The event configuration doesn’t trigger the recording but rather stores summary logs including start and end time, duration, severity and magnitude of the event. All events can be displayed in a tabular or scatter charts as CBEME/ITIC.
