Power quality issues can cause serious problems in an electrical facility. Poor power quality can cause problems like loss of sync of motors, erratic operation of sensitive electronic equipment, electromagnetic interference and increased power draw from the electrical mains.
Distortion, harmonics and other voltage variations are generated in the power line due to non-linear loads. Ballasts, rectifiers and switched-mode power supplies are the common culprits that cause degradation of power quality. To help correct power quality issues, engineers use a compensation network to suppress power line distortion.
The amount and type of distortion present in the electrical line helps determine the proper amount of compensation needed to counteract the problem. To determine the amount and type of distortion present in the power line, a technician uses a power quality analyzer. This device helps sort out the harmonics, power parameters, voltage events and distortion.
For excellent power quality analysis, you might want to check out power quality analyzers from Fluke. Some of the popular models you might be interested in are the Fluke 1735 and 1750 Power Loggers. Read on for a comparison of the two models.
