Ya sea para garantizar la continuidad del servicio o por un fallo o por un funcionamiento inusual, las pruebas in situ de los motores son valiosas para garantizar que no existan condiciones de ensamblaje anormales después de la reparación del equipo, evitando así el desmontaje de equipos que están en buen estado. También confirman si la reparación se ha realizado satisfactoriamente.
This presentation covers what partial discharge is, how partial discharge damages insulation, and some testing methods.

Spectrum analysis is the primary tool for analyzing vibration problems. Yet, a lot of useful information can be acquired by tracking the vibration characteristics as power is disconnected from the machine.
Simple diagnostic tests—such as bump tests and speed‑variation checks—can be used to identify resonance as the cause of high vibration in rotating machinery. By recognizing when vibration frequencies align with natural frequencies, technicians can diagnose resonance issues early and avoid unnecessary corrective actions.
Este artículo explica cómo pruebas diagnósticas simples —como las pruebas de impacto (bump tests) y las verificaciones mediante variación de velocidad— pueden utilizarse para identificar la resonancia como causa de alta vibración en maquinaria rotativa. Al reconocer cuándo las frecuencias de vibración coinciden con las frecuencias naturales, los técnicos pueden diagnosticar problemas de resonancia tempranamente y evitar acciones correctivas innecesarias.
Many service centers are unable to perform full-load testing of large DC machines. The good news is that there are specific tests that can be performed on a DC motor to verify the integrity of windings, the correct relative polarity of armature to interpoles, and proper running performance. This article explains specific tests that can help ensure a motor operates properly when the motor is installed.
Muchos centros de servicio no pueden realizar pruebas a plena carga en máquinas de corriente continua grandes, sin embargo, la buena noticia es que existen pruebas específicas que permiten verificar la integridad de los devanados, la polaridad relativa correcta entre la armadura y los interpolos, y el adecuado funcionamiento del motor. Este artículo explica pruebas específicas que pueden ayudar a garantizar que el motor funcione correctamente una vez instalado.
Equipping a pump test facility for variable speed operation can provide greater flexibility and expand opportunities to evaluate pump performance.
Emplear velocidad variable durante las pruebas puede brindar mayor flexibilidad y ampliar las oportunidades para evaluar el rendimiento de las bombas.
