A polarization index is a 10-minute timed insulation test using a megohmmeter to measure resistance to ground. If you plot or graph the results incrementally, it will give you a profile of the resistance to ground. There are five distinct patterns that we'll get...
So much emphasis is placed on emissivity that in many cases reflectivity is not given the respect and attention it deserves. When capturing high-quality infrared data, reflected or background energy must be known, along with an understanding of how it is influencing the image and data.
Organizations may be tempted to throw IIoT-enhanced devices and software at the wall to see what sticks. This may be an option, but it’s not conducive to a successful maintenance program rollout...
