GF438II Portable 3 Phase Power Quality Analyzer and power quality meter with 3000a current probe

GFUVE GF438II 3 phase power quality analyzers can help you discover the state of health of your power systems. Designed to meet the needs to the intended measurement task, power quality analyzers help you beprepared for any power quality issues.The Power Quality analyzers that can monetize the cost of energy waste due to poor power quality. More powerful sampling options, greater accuracy and larger memory makes the GF438II better for longer term, higher resolution or more demanding power quality studies.

The GFUVE GF438II power quality analyzer enables you to identify issues and measure energy loss giving you specific insight into the amount of loss in dollars associated with things like effective power and withpoor power quality characteristics such as reactive power, unbalance, distortion, or neutral current. To maintain the health and safety of such infrastucture, a reliable power quality analyzer is needed. This power quality analyzer should be capable of not only logging single to multi-phase power, but also trend and monitor anomalies in the power system such as voltage sags,swells and dips, as well as flicker, inrush current, and demand changes.

A power quality compression algorithm is an algorithm used in the analysis of power quality. To provide high quality electric power service, it is essential to monitor the quality of the electric signals also termed as power quality (PQ) at different locations along an electrical power network .
The POWER QUALITY ANALYZER GF438II provide robust support for field personnel who need to analyze power characteristics in the form of measurement capabilities that reliably captures the full range of power anomalies and exceptional ease of use throughout the entire user experience, from connecting the instrument to recording data.

GF438II handheld three phase power quality analyzer offer the best ability in power quality analysis, GF438II handheld power quality analyzer help locate, predict, prevent and troubleshoot power quality problems in three phase and single phase power distribution systems. Additionally, GFUVE patented energy loss algorithm, unified power measurement, measuring and counting energy losses due to harmonics and unbalance issues, allowing the user to pinpoint the origin of energy losses in the system.

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.
