Selecting a Power Analyzer on Amazon.com
Power quality is a measure of the stability and consistency of the electrical power supply within a facility. Ideally, an electrical supply will deliver a consistent voltage magnitude and frequency. Realistically, a power supply can be affected by disturbances to voltage or frequency that interrupt the distribution within a facility or impact the efficiency of the system. Power disturbances can damage products or equipment, and inefficiencies in the power distribution system can increase utility costs. The quality of power is commonly described by several parameters, including the continuity of the power service; variation in voltage magnitude such as spikes, sags, or flicker; and harmonic frequencies in the power supply.
To help ensure that a facility’s power distribution system can support variations in power quality, technicians and electrical engineers use tools to measure, monitor, and troubleshoot electrical power for anomalies, interruptions, and inefficiencies. A power quality analyzer, also called a power quality meter, helps technicians maintain commercial, industrial, and residential electrical power supply systems.
A basic power analyzer can measure and record single-phase voltage events including flicker, transients, and harmonics to troubleshoot electrical problems. It can analyze voltage during short time frames, such as a few seconds to 20 minutes. For a more thorough analysis of power, some meters monitor or record parameters such as current, frequency, power factor, peak demand, phase sequence, and active, reactive, and apparent power in three-phase systems. These comprehensive meters can take readings over time periods ranging from seconds and minutes to an hour or months in order to track any changes and variations in power quality.
Some meters are portable and come with a display so operators can review data in the field. These meters may enable data transfer via a USB cable to a computer for review and documentation with analysis software. Other meters are designed to be installed within a system and automatically transfer data to a central computer for analysis. Manufacturers include Fluke.
