MCSA
Five Minute Facts
What Can We See with ESA and MCSA?
If I take my data between the controls and the motor, current signature shows downstream toward the load and process, while voltage signature shows upstream toward the generator. And it shows the whole system at once…

The Detection of Gear and Bearing Defects Using Electrical and Current Signature Analysis
In this presentation we will discuss how to use ESA/MCSA to detect bearing and gear defects in a variety of driven equipment including geared elevators, cooling towers, and other applications, even when we are looking at a few RPM. We will discuss how to determine the correct frequencies as well as how to determine the defect severity amplitudes in -dB, and how to isolate the machine you are testing from nearby machines. Several case studies will be presented including an AC building elevator, a cooling tower, and at least one complex (multi-stage) gearbox using both data collection and continuous monitoring.

5 InsightCM™ Features for Remote Diagnostics
Reliability engineers can’t be in two places at once. But when assets from two different plants are raising concern, how does the engineer figure out which one is more likely to contribute to an outage? Remote diagnostics help maintenance teams decide where to deploy valuable resources like subject matter experts, troubleshooting equipment, and spares.......

Electrical and Current Signature Analysis of Electric Motors and Gearboxes
In this live webinar, we will discuss how ESA is used to evaluate electric motors, couplings and gearboxes of several types including speed reducers, increasers and cooling tower boxes. Electrical Signature Analysis (ESA) technology is used to review incoming power quality and the machine through the entire powertrain........
