2014 NETA Powertest Conference

I’ll be presenting “Simplified Motor Relay Testing” at the 2014 NETA Powertest conference in Denver.

Here’s an excerpt from the NETA Powertest website

Join us at PowerTest 2014 and Energize your Future at the premier electrical acceptance, maintenance, and safety conference in Denver, Colorado. PowerTest 2014 will leverage expertise within the industry, providing countless opportunities for professionals to expand their knowledge, examine new ideas, and shape not only their future, but that of the electrical power systems industry as well. Denver is a city that has inspired many to seek new challenges, advance their knowledge, examine new ideas, and shape the future. A perfect fit for PowerTest 2014.

PowerTest 2014 energizes and renews the commitment to improving safety and reliability, sharing experiences, and growing the collective knowledge within the electrical power systems industry. This event brings together experts, technicians, managers, inspectors, contractors, engineers, manufacturers, operators- industry leaders all working to build a better future on a global scale.

Here is the abstract for my paper at the 2014 NETA Powertest Conference

Motors have unique characteristics (starting time, inrush current, variable loads, temperature sensing, etc. that can require specialized protection to ensure that the relay assigned to protect a motor can tell the difference between a normal condition and a fault condition and respond accordingly. These specialized protection features can make motor relay testing a little frustrating because of all the different protection schemes applied that can overlap. This paper will describe the most commonly applied elements and how to successfully test them with step-by-step procedures that can be applied to any motor protective relay from any manufacturer to make testing more efficient and effective.

Feel free to send me suggestions for what you’d like to hear in this paper.
