“Human error” is an often-cited cause or contributing factor in accidents and failures. We routinely see this with our plant equipment. But, identifying ways to reduce or eliminate “human error” can be challenging without a structured process for indentifying and...

One of the least understood, yet critical, components of power quality is the grounding system. While we cannot cover all variations of these systems, it’s important to note that the primary methods are grounded/bonded; resistance ground; and,...

As noted in previous articles in this series on motor-driven equipment and electrical-system-reliability issues in today’s plants, the primary electrical concern is the supply to electric motors, i.e., the voltage. An electric motor is electrically designed around the...

Voltage unbalance and its most severe form, single phasing, cause up to 14% of power-quality-related motor failures. It’s important to understand that maximum current unbalance is not defined in standards for electric motors in their operating environment,...

Complaints about problem parts in plant operations seem almost endless these days. They come from all sectors and go on and on and on. Maybe you’ve heard some, or even expressed concerns of your own that are eerily similar to the following: “These bolts, right...

“D’ya think I’m stupid? Checklists are for dummies.” “I know what I’m doing. I’ve done it for years.” “Why would I ever need a checklist?” These types of remarks sum up what, even now, is a widely held view among maintenance and reliability teams on many plant floors....

Power quality involves a variety of impacts on the Voltage supply, the Current, and the grounding system While many standards and documents emphasize one part or another, the reality is all of these factors impact each other. Unfortunately, except for...
