Wireless PQ Monitoring with the Javelin and Revolution
Introduction The Javelin is a utility-friendly cell router, providing communication access to devices in the field such as capacitor controllers, reclosers, voltage regulators, and DER inverters. A Javelin may also…
Canvass Multiburst
MultiBurst is a feature of Canvass which provides a secondary user interface for easily requesting and receiving real-time data from multiple devices at the same time. This allows for quick,…
Recommendations for Voltage Sags
Voltage sag is one of the most common power quality problems. The consequences for not troubleshooting a voltage sag complaint isn't the resulting damage that can be done to electrical…
Holdoff and Aggregation with Canvass Alerts
Email/SMS alerting from Canvass is a powerful feature providing real-time notification about distribution events and equipment problems in the field. Some notifications require immediate truck rolls, and others are less…
Waveform Capture with Transient Capture Overlays
PMI Revolution recorders can record waveform captures and, with the transient capture option, high-speed microsecond-level transient captures. Transient captures have a much higher sampling rate than waveform captures but have…
Advanced E-Mail Alerts in Canvass
One of the most popular, and useful, features in Canvass is the Distribution List, which allows any chosen alert or event, from any Canvass-enabled device, to be transmitted by email…
Alert Level Programming and Analysis
The proliferation of cellular networks has allowed for quick access to information when it is needed. This quick access to information is available from all of PMI's cell enabled products…
New ProVision Release for Handling Large PQ Recordings
With the introduction of the cell Guardian, 1 GB of memory in a PQ recorder is increasingly common. Although the resulting large files can provide a wealth of data, they…
THD Waveform Capture Triggering
The simplest waveform capture triggering is based on RMS voltage or current changes. While sufficient for voltage sags, recloser operations, etc., more complex events such as cap bank switches, narrow…
CBEMA Graphs Revealed
The CBEMA (Computer Business Equipment Manufacturers Association) curve and the ITIC (Information Technology Industry Council) curve both refer to a similar method to visibly represent voltage events. A graph of…
Wireless Power Quality
The time and cost of deploying PQ instrumentation only to return later in order to retrieve it (without the guarantee that the PQ anomaly has occurred) is often times exorbitant.…
