If you were to ask a handful of customers what they consider a ‘power surge’ to be, you would get a multitude of answers — anything from a lightning strike…
Revolution Download in PQ Canvass
Revolution meters are compact, cellular-connected power monitors. Unlike the Tensor, Seeker, Guardian, and Bolt devices, which initiate their own uploads to PQ Canvass, Revolutions do not push their recordings to…
Heat Pumps and the Winter Peak
As American homes shift from gas furnaces to heat pumps, the load that used to burn gas now arrives at the residential transformer — in winter, at the coldest hours,…
Understanding Voltage Phase Rotation in Three-Phase Systems
Three-phase power systems depend not only on equal voltages between phases but also on the order in which those phases reach their peaks — a property called phase rotation. Incorrect…
Analyzing Motor Startups with the Bolt
Induction motors are ever popular in today’s world and can be found in most areas of life — industrial, agricultural, and even residential settings. These motors can have high inrush…
