The Trifecta of Motor Maintenance

by Noah Bethel

The odds of picking the first place winner in a horse race are slim. The odds of picking the first, second and third place winners are even less favorable, but when it happens, the trifecta payday is big!

What You’re Missing if You Don’t Perform Hipot Tests

What You’re Missing if You Don’t Perform Hipot Tests

High potential ("hipot") tests are critical for detecting insulation weaknesses that meg-Ohm ("megger"), PI and other low-voltage motor tests can't find. This i Presentation reveals how DC hipot tests find ground-wall insulation problems that can't be found with low-voltage tests.

What You’re Missing if You Don’t Test Motors Using the Surge Test

What You’re Missing if You Don’t Test Motors Using the Surge Test

Surge tests safely find insulation problems no other electric motor test can. Get the facts that debunk erroneous opinions and lingering misconceptions about surge testing, including how it impacts the longevity or integrity of motors.

Increasing the Lifespan of your Motor

In mission critical industries such as pharmaceuticals or paper and pulp, a motor malfunction can translate to millions of dollars in lost profits. Looking after the bearings in your motor by improving power quality increases its lifespan and reduces maintenance related downtime.

Why Surge Tests Are Critical For Successful Motor PdM
Asset Condition Management

Why Surge Tests Are Critical For Successful Motor PdM

1) Motor insulation degrades naturally over time, but many factors can accelerate degradation leading to shorts and motor failure.
2) Surge tests play an important role in assessing the strength of insulation, and allow maintenance personnel to avoid costly unexpected motor failures and downtime.
3) Surge tests with SKF static motor analyzers can be performed over and over again on a motor with no tangible degradation to insulation strength or motor health and performance.

Overcoming a Typical Testing Dilemma - We Want to Test, But We Don’t (really) Want to Find Anything

Being both Instrumentation & Electrical (I&E) planner and electrical testing supervisor can be an uncomfortable position. You want to do your job well and keep the plant running at tip-top shape, but if you find a motor or process problem, you know it will cost money to fix it. It can be the proverbial double-edged sword. For those of us in the electric motor testing business, this is an all too familiar situation. In other words, what are the repercussions of a test failure? How will failing a test affect the motor? Could it be out of commission? How much money is it going to cost to replace or repair? Is higher management going to go along with your findings and be open to doing the right thing?
