Power Quality Instrument Selection Guide

Power Quality Instrument Selection Guide
Power quality instruments help users diagnose the performance of their electrical systems. By troubleshooting, logging and recording key power characteristics, users can quickly determine key parameters and discover faults. Choosing the right power quality tool, however, can be difficult, with ambiguous product names as diverse as power quality meter, power measurement logger and power quality recorder.

The following guide is intended to help electrical testing personnel to choose the best power quality instrument for their application.

 

Power Loggers

Fluke 1735

Power Quality Analyzers

 
Dranetz power analysis instruments

Basic tools for discovering where energy savings are possible, power loggers conduct energy and load studies and offer insight into electrical issues with detailed reports. A power logger is also ideal for validating voltage quality and finding power quality trends. Power recorders fall into this category, devices designed for long-term electrical studies that reveal hidden or sporadic electrical trends which only manifest over time. Common names for this type of instrument include power quality logger, power quality recorder and energy logger.
 

Power quality analyzers troubleshoot electrical issues. A power quality meter locates power quality faults and perform load studies, energy waste assessments and quality compliance testing. Power quality analyzers display electrical diagnostic information live, offering the advantage of immediate access to data. Other common names for these products include power quality meter, power quality monitor and energy analyzer.
