Continous Waveform Recordings

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


Supreme Trends Resolution

The G4500 portable power quality 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.

Harmonics & Inter-Harmonics Analysis

The G4500 portable power quality analyzer 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.

Comprehensive Event Mechanism

The G4500 portable power quality meter 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 G4500 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.
