Analyzing Portable Power Station Inverter Power Quality
An engineer at PMI purchased a portable power station and wanted to verify the quality of the inverter before attaching sensitive electronics. The steps used to quantify the output quality…
Viewing Power Consumption in the Cloud
Energy usage metering (in kWh) is now available at-a-glance from the PMI Canvass web application. This new feature will save you time while you diagnose internal and customer-facing issues by…
Interharmonic Analysis with Python
Traditional harmonic analysis in electrical systems has revolved around looking at the spectral content on, well, the magnitudes of harmonic frequency components. The IEEE 519 specification provides guidelines for measuring…
Automatic IEEE 519 Report Generation
The IEEE 519-2014 standard specifies measurements, analysis methods and limits for harmonic voltage and current. The 2014 version is very rigorous with multiple sets of limits, time intervals, statistical groupings,…
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…
Using PMI Boomerangs with an RTAC
Introduction In addition to PMI's cloud-based Canvass system compatibility, Boomerang distribution monitors including a DNP3 port for use in SCADA. Advanced distribution programs such as volt/VAR optimization, DER management, and…
Impact Loading
Impact loading occurs from the inrush current of large motors, welding apparatus, electric arc furnaces, or similar loads. The current pulses are less than short circuit values but may be…
ProVision Recording Templates
This white paper covers the creation and use of predefined recording templates in ProVision. PMI recording devices can be initialized with a number of configurable settings. Configurable settings include recording…
Introduction to Solid State Power Transformers
The Solid State Transformer (SST) may be a groundbreaking innovation in electric distribution, replacing the century-old "pole pig" with a modern, active power supply architecture. Although still in the early…
