Crest Factor in Vibration Analysis
The Crest Factor (CF) is a fundamental metric in vibration analysis, defined as the ratio of the peak amplitude of a time waveform to its root mean square (RMS) value This dimensionless ratio serves as an indicator of the severity of transient or impulsive events in a vibration signal.

Electrical and Current Signature Analysis of Electric Motors and Driven Equipment
The paper identifies the approach for electrical and mechanical conditions through direct and belt coupled applications and how driven equipment, and loads are evaluated through those coupling types. We will focus on two types of technologies including a 3-phase voltage and current ESA and a single-phase CSA system. The focus will be on CSA but will distinguish what the addition of voltage as part of the measurement will provide.

Electrical and Current Signature Analysis of Unloaded and Loaded Electric Motors
In this presentation we will demonstrate both ESA and MCSA using two separate systems comparing various loads. This will also demonstrate how expert-ESA/MCSA combined with ML/AI can both immediately detect existing conditions as well as long-term anomaly detection. We will also use the opportunity to demonstrate changes in losses in bearings under different load conditions.

Real-Life Case Study: Sensorless Pump Performance Monitoring with Electrical Signature Analysis Technology
Join us for a deep dive into a real-world case study where we analyzed the performance of a dirty water pump using Electrical Signature Analysis (ESA)—without the need for external sensors like flow or pressure. In this session, you’ll see how our system detected low-efficiency operation, identified the pump’s operating point on the curve, and provided actionable efficiency improvement suggestions tailored to the customer’s application priorities.

The Art of Bearing Failure Analysis
Bearing Failure Analysis is an "art", but not all who does the bearing failure analysis is an "artist". While I was conducting a bearing failure analysis of a large size spherical roller used in a crushing application, moisture corrosion was the main reason for the bearings to fail...
