We compared the photometric and radiometric quantities in the visible, ultraviolet, and infrared spectra of white light-emitting diodes (LEDs), incandescent light bulbs and a compact fluorescent lamp used for home illumination. The color-rendering index and efficiency-related quantities were also used as auxiliary tools in this comparison. LEDs have a better performance in all aspects except […]

This paper presents a methodology for obtaining the parameters of the equivalent circuit for an induction motor from the information on the nameplate and manufacturer catalog data sheet. The proposed method is straight and noniterative. The variation in rotor parameters for deep bars or double squirrel-cage rotors is modeled and presented as a function of […]

A model proposal to determine the influence of wind over temperature measurements when conducting outdoor infrared (IR) themographic inspections is addressed in this paper. A wind velocity-dependent temperature reduction factor is developed and applied in order to estimate the target temperature in the absence of wind, which is considered as the worst case. The model […]
