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…
DER Control and Management with the Eclipse
The Eclipse provides the ability to control remote equipment in the form of a DER inverter. DER refers to Distributed Energy Resources and is used to describe various decentralized sources…
ProVision Customization
The “out-of-the-box” ProVision layout is designed for general use. Fine tuning and customizing the ProVision environment streamlines PQ analysis and maximizes use of the screen workspace. We will explore the…
Power Quality in Traffic Signal Cabinets
The first electric traffic signals were installed over 100 years ago but now are a ubiquitous aspect of modern life. Today's intersections are far more complex, with a cabinet of…
Feeder Resonance
Substation circuit loads are mostly inductive, dominated by distribution transformers and large motors. Canceling a portion of this inductance with Power Factor Correction capacitors (PFCs) improves power factor by reducing…
An Overview of Harmonics and Power Quality
Harmonic distortion is a broad, complex power quality issue with significant economic impacts for electric utilities and end users. Distorted current waveforms from end-user loads create excessive heating for utility…
Viewing PQCanvass Boomerang Data in ProVision
Boomerangs smart grid sensors transmit RMS voltage, current, and power data to cloud-based Canvass and PQCanvass systems. Canvass/PQCanvass provide web-based data analysis tools, email/SMS notifications, and long term data storage…
Tips on Transformer K-factor
Transformer loading is ultimately limited by internal heating caused by load current flow. Some heating is caused by resistive losses in the transformer winding. Another important heating source is eddy…
RMS Measurements and Harmonic Analysis
The RMS value is used to quantify the overall "size" of a waveform with a single number. By extension, harmonic amplitudes can be used to describe a complex waveform with…
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…
Transferring ProVision Recordings to PQCanvass
We've added a major enhancement to ProVision - the ability to sync recordings with PQ Canvass, PMI's cloud-based PQ data analysis system. The implications of this are profound because you…
