GF438II three phase portable power quality and energy analyzer With Inrush current & High-order harmonics

GFUVE portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The new and improved GF438II is a power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. New features include the ability to drive current sensors straight from the PQA and enhanced recording capabilities.

The GFUVE GF438II power quality analyzers are designed for users who need to get to the solution of the power quality problem as quickly as possible so that they can minimize expensive downtime.

Measure multiple parameters simultaneously to quickly understand overall power quality health
View data as simple digital values or more detailed trend graphs that give you fast insight into changes over time, waveforms, and phasor diagrams
Organize data in tabular format so you can quickly correlate parameters like magnitude, duration, and time to the issues you are experiencing in your facility

FUNCTIONS

GF438II PQA can measure all parameters at once, including power, harmonics, and anomaly waveforms.

Transient voltages
Voltage swells
Voltage dips
Interruptions
Frequency fluctuations
Inrush current
Harmonics
High-order harmonics
Unbalance

When an event occurs, the instrument records the instantaneous waveform for 0.2 seconds.
Triggers can be set for all event parameters in parallel, and you can check recorded data on the display while measurement is in progress.

When a voltage swell, dip, or inrush current event occurs, the GF438II PQA can simultaneously record 1/2 RMS value fluctuations for 30 seconds.
