What is that Catchy Tune on My Transformer
Nope. Neither dry nor oil-filled transformers are supposed to be noisy by nature. When you hear noise it is often the result of something from power factor conditions, harmonics, core…
Energy Monitoring Dashboard
Some of our clients use the ECMS-E1 and ECMS-32's for site energy monitoring. The hybrid edge system that we have developed provides the ability to simply create dashboards such as…
Workforce and Infrastructure Discussion with a Lineman

Analyzing Transformer Sound with a Phone – Poor Man’s Analysis
So, you are out on a job and there is a noisy transformer - you know, that humming noise that we are all familiar with. However, something doesn't sound quite…
Machine Learning IoT in a Box: Lessons from the SMRP Conference
Lately there has been a lot of discussion about the differences surrounding electric motor prognostics with expert systems and machine learning IoT devices. The difference became glaringly obvious right before…
How to Evaluate an Electric Motor with Voltage Variance and Unbalance
Voltage variation and unbalance are defined separately within NEMA MG-1. However, in real-life applications these conditions exist at the same time. In this paper we will discuss combined voltage variations…
