Features
How It Works
The PQ400 electrical measurement window is a permanently installed interface that provides technicians with near instant access to electrical panels for making critical power quality and energy measurements. The PQ400 installs using a standard step drill bit and electro-hydraulic hole punch (114.3 mm, 4.5" hole diameter), and allows users to make three-phase voltage, current and ground connects covering most measurement configurations. Once installed users can simply unlock the window cover, lift the lid, and connect the voltage leads of the logger or analyzer. Then, connect the leads for the current sensors and start making critical measurements. Once complete, simply remove the voltage and current connections from the front panel interface and lock the window lid, leaving the internal connections in place for future use.
Applications
Infrared cameras, also called thermal imagers, are useful for troubleshooting motor problems as well as for monitoring motor condition for preventative maintenance in power generation, manufacturing and commercial plants. Thermal images of motors reveal their operating condition as indicated by surface temperature. Such condition monitoring is important as a way to avert many unexpected motor malfunctions in systems that are critical to manufacturing. The onset of motor failures can often be detected by a variety of techniques, including vibration, ultrasound and thermal imaging.
In this article, we cover why use thermal imaging and what to scan, as well as some notes on what to look for, including shaft misalignment.
Read the ArticleComplete three-phase voltage and current measurements 50% faster! We're confident in this because it's been tested at customer sites. The new clamp meters from Fluke (models 377 FC & 378 FC) feature FieldSense™ technology where voltage and current can be measured simultaneously with the clamp jaw. Meaning, these clamp meters can be used to make sequential line-to-ground measurements and current measurements that result in calculated line-to-line voltage measurements and phase rotation information.
In this application note, we walk you through the old versus the new way of doing phase-to-phase measurements along with step-by-step instructions on how to make these measurements.
