Condition Based Monitoring Reduces Energy Use In Municipal Utility District
Instrumentation led these users to more informed decisions. By Mike Bjorkman, ALL-TEST Pro, LLC & Stephen Hogue, Less Watts Inc. Unlike residential consumers, industrial and commercial companies pay for the reactive kilovolt-amps (kVA) demand power they use along with the active kilowatt (kW) energy they consume. Each electrical power provider [...]
Power Plant Uses Electrical Signature Analysis for Performance Assessment
One nuclear power generating facility, located in the Northeastern United States, relies on four vertical service water pumps to feed water to a heat exchanger which cools the sealed ultrapure water/steam that drives the turbine generators. Of the four identical service water pumps, all of which had [...]

Machine Monitoring and How ESA Technology Can Upgrade Your Plant’s Reliability
By: William Kruger, ALL-TEST Pro More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either [...]
Reducing Costs with ESA and MCA™ Technology
Managing Rotating Equipment More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates [...]

Author: Aaron Schnelle, Technical Support, and Richard Scott, General Manager, ALL-TEST Pro, LLC. The Company During the demonstration of an ALL-TEST PRO 5TM Motor Circuit Analysis instrument (de-energized motor tester) a member of ALL-TEST Pro Technical Support Team tested a 10HP, 4-pole, T-frame motor that had been removed from [...]
Motor Vibration Analysis Equipment: Vibration Monitoring vs ESA
Many people only notice problems with motors when the motor may physically shake, vibrate, overheat, or make an audible sound, before taking the proper action to fix the issue. Vibration monitoring sensors have become more commonly used but sometimes do not find the true issue within the [...]
Motor Diagnostics: The Multi-Technology Approach
Introduction There has been a persistent misconception that there is a ‘magic bullet,’ in the form of a Condition Based Monitoring (CBM) instrument, that will provide all of the information that you need to evaluate the health of your electric motor system. This misconception is often brought about [...]
Electric Motor Condition Monitoring: What It Is and Its Benefits
Electric motor condition monitoring is a process of monitoring the health and performance of an electric motor. It helps to detect any potential issues before they become serious, thus avoiding costly repairs or replacements. This process can be done manually or using automated techniques such as vibration [...]
