Measuring Frequency with PMI Recorders
Line frequency is the most tightly controlled parameter in the electrical distribution system. Since almost all generation in a region is connected essentially in parallel, the frequency is inherently synchronized…
Bluetooth Security
This white paper will discuss several of the security concerns regarding PMI's Power Quality Recorders and their implementation of the Bluetooth protocol. Bluetooth security concerns have been tackled for many…
Formulas for Power and Harmonic Measurements
PMI recorders use a variety of algorithms to compute RMS voltage and current, real, reactive, and apparent power, true and displacement power factor, and phase angle. The formulas for these…
Increasing Range When Using Bluetooth
This white paper describes what Bluetooth is and identifies what PMI products use Bluetooth technology. It also covers how to increase the range of a Bluetooth system and improve data…
