Recording Interharmonics with the Revolution
Interharmonics are on the rise because of large non-linear loads and sources being introduced to the distribution network, in particular large Variable Frequency Drives (VFDs) and inverters for distributed generation.…
Hardware for Power Quality and Distribution Monitoring
PMI offers an array of monitoring devices for just about any utility distribution monitoring need. Data needs, location, and communications requirements are all factors involved in selecting the right monitor…
Sampling Rate in PQ Recorders
A common specification in power quality recorders such as PMI's Revolution, Guardian, or Eagle products is the sampling rate of the device. Users know this is an important number and…
Transient Capture vs. Waveform Capture
Most PMI recorders include waveform capture, and the Revolution optionally includes a high-speed microsecond-level transient capture system. Although PMI waveform capture and transient capture seem very similar on the surface,…
Using the Revolution Mounting Bracket
The PMI mounting bracket provides a variety of methods to temporarily or permanently attach a Revolution or 3-phase Boomerang to a metal enclosure, mounting plate, or many other points. Internal…
Oscillatory Transient Ring Frequency
This white paper provides details on how to estimate ring frequency caused by resonances formed between power corrections capacitors and inductive loads using ProVision. Waveform data captured using PMI's Eagle…
SNTP Configuration for the Revolution
PMI's Revolution power quality recorders are available with Ethernet/networking capabilities which are easily configurable to allow quick connection and communication over a company's network. One of these network capabilities is…
Measuring PLC AMR Signals with the Revolution
Many AMR (automatic meter reading) systems rely on PLC (power line communication) signals for data transfer. These signals travel on the 60Hz distribution network and can be affected by power…
Comparison of Eagle 440 and Revolution PQ Analyzers
PMI manufactures several stand-alone power quality analyzers that are designed to fit in tight enclosures and wirelessly transmit recorded data. This paper outlines the differences between two of those devices,…
Optimizing Memory in a Recorder
This white paper describes the proper steps to optimize your recorder's memory for longer record times and better resolution of data.
