PX5-XFAST PowerXplorer Power Quality Meter
The Dranetz-BMI PowerXplorerTM PX5 is a portable, hand-held, eight-channel power
quality meter/monitor. This cutting-edge power quality instrument is designed with a
color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. It can
monitor, record and display data on four voltage channels and four current channels
simultaneously.
PX5 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for
accuracy and measurement requirements. It can do PQ-optimized acquisition of power
quality related disturbances and events. It is designed with a statistical package called
Quality of Supply (QOS), with monitoring and setup protocols set to determine voltage
measurement compliance required for EN50160 monitoring. European standard
EN50160 requires that measurement parameters must be within a specified percentage
for 95% of the time.
Model PX5-XFAST is equipped with the high speed sampling analog board for
microsecond
transient detection digitization and analysis. The PX5-XFAST performs
measurements for
50/60 Hz power frequency systems.
