INTRODUCTION
The Dranetz HDPQ
®
Xplorer, Xplorer 400, Guide and Visa are portable,
hand-held, eight-channel power quality meter/monitors which are very
similar in operation, although the Xplorer also has a high speed sampling
board for capturing the details of very fast transients. The features
common to all monitors are covered in this document, and the Xplorer
name will be used to represent all four instruments unless otherwise
noted. These cutting-edge power quality instruments are designed with a
7” WVGA wide screen LCD, using touch screen technology. They can
monitor, record and display data on four voltage channels, as well as
four current channels simultaneously.
The Xplorer 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.
The Xplorer also allows you to perform automatic setup or to customize
threshold settings for power quality or energy/demand. The power quality
and energy/demand dashboard interface helps you monitor and manage
energy consumption including utility costs.
The Xplorer firmware can monitor power quality and energy/demand
phenomena for troubleshooting and/or compliance purposes. It can
record inrush conditions, carry out long-term statistical studies to
establish performance baselines, and perform field-based equipment
testing and evaluation for commissioning and maintenance. The
firmware integrates an intuitive instrument setup procedure to ensure the
capture of all relevant data for additional post process analysis, report
writing, and data archiving using other compatible Dranetz software
applications such as Dran-View
