Equipment Diagnostics: Technical Articles
About These Articles
Articles on ESA, vibration analysis, tribology and the principles and applications of condition monitoring.
Most articles below are in Japanese. Japanese-language articles link directly to their Japanese pages.
The Physical Basis of ESA and Its Differences from Vibration Diagnostics (Japanese)
A comparison of the physical principles and diagnostic information underlying vibration analysis and ESA.
Vibration Diagnostics and ESA: Mechanical and Electrical Analogies (Japanese)
How mechanical and electrical analogies help explain the complementary roles of vibration diagnostics and ESA.
Equipment Deterioration and Energy Loss: The ESA Perspective (Japanese)
Equipment deterioration can increase energy consumption as well as the risk of shutdown. This article considers that relationship.
Wind Turbine Diagnostics and Condition Monitoring with ESA (Japanese)
An introduction to wind power diagnostic services provided in cooperation with our sales partner, WEST JEC.
ESA: Application Scope and Diagnostic Value (Japanese)
The range of equipment that can be assessed using ESA, including three-phase AC motors and generators.
The Motor as a Sensor: Principles of Electrical Signature Analysis (Japanese)
How motor air-gap interactions, amplitude modulation and FFT analysis help reveal changes in equipment condition.
Equipment Diagnostics: Foundations of Predictive Maintenance and Condition Monitoring (Japanese)
The purpose of equipment diagnostics in preventing unexpected failures at factories, power plants and infrastructure facilities.
