En este documento exploraremos múltiples consideraciones para evaluar la condición de una conexión eléctrica que presenta anomalías térmicas. Se debe indicar que en este documento nos limitaremos a conexiones eléctricas y no a dispositivos como: breakers, fusibles, capacitores, transformadores, etc. Pero podría aplicarse a las conexiones de estos dispositivos, aunque con algunas salvedades que se indicaran más adelante en el documento.

Aprenda porque la temperatura o el aumento de temperatura de una conexión eléctricaanormalmente caliente se debe reportar “por lo menos…”. Entre las razones mencionadas: la emisividad puede ser menor a la considerada, la temperatura en el lugar de la falla será más caliente que la presente en su superficie, pues puede existir viento, convección forzada o la carga puede aumentar.

Assume your company has seen the value and decided to invest in electric motor testing (EMT) as part of their predictive maintenance program. They have selected you to introduce this new technology into its process. This paper will address how one can effectively establish EMT as an integral part of their reliability maintenance program.

Read about a study that was performed on twenty-one motors. Eighteen of them were identical motors in identical service with the same model number and sequential serial numbers. This created a unique situation where motor data could be compared and analyzed.

Since the development of electric motor testing equipment back in the 1980’s, the technology has evolved to encompass multiple uses beyond the original intended purpose. This paper addresses how EMT is successfully used in the commissioning of new equipment.

Read about the basic key elements for a motor management system and discover an understanding of why a motor management system is much more than just a reliability and testing program. In fact, motor reliability and testing are two key components that make a significant contribution to a motor management system.

While vibration analysis and infrared thermography have been widely used for years as part of predictive maintenance programs, Electric Motor Testing(EMT) is a relative newcomer to condition monitoring. In reality though, the tests utilized by modern EMT systems have been around for years. Learn more about this technology in this white paper.

Electric motor maintenance has come a long way in the last 25 years. A quarter of a century ago one of the primary methods for testing motors was “megger” testing. Today, there are more choices and assessment of motors and associated rotating assets can be done quickly and efficiently, if the right technologies are implemented. This white paper will take a look at how we arrived at this point in the motor testing timeline by discussing what methods are available, how they work, and how they can be combined for superior results.

Thermal imaging has long been used for discovering, understanding, and interpreting the temperature of objects within our environment. From the advent of thermal imagers in the 1950s to present day – we’ve continued to evolve and discover new applications. Infrared thermography provides a variety of different testing techniques for a wide range of components, machines, and structural materials, allowing trained thermographers to find subsurface anomalies. In this white paper from The Snell Group, learn about the use of thermal imaging for nondesctructive testing (NDT) technologies.

Engineers are usually taught the basic forms of heat transfer, often with the assumption that surface temperature is an independent variable driving the heat transfer. The reality is, however, that surface temperature is an interface between different forms of heat transfer and responds as a dependent variable. This paper will provide an overview of surface temperature as a response to different forms of both internal energy generation and external environment.
