Abstract Hot-spots appearing on several RE123 ceramics upon application of external voltage have been reported to show sensitivity towards different oxygen partial pressures. In this paper, influence of hot-spot temperature in the range of 160–810 °C on oxygen sensing behavior of Er123 sensor rods is reported.

A Simple Model for Calculating Transformer Hot-Spot Temperature
IEEE Transactions on Power Delivery, 2009A simple model for calculating the hot-spot temperature is introduced. The model is based on the hot-spot to ambient gradient. The model considers the changes of the oil viscosity and winding losses with temperature. The results are compared with temperatures calculated by IEEE Annex G method and measured results at varying load for the following ...

Investigation of Hot-Spot Temperatures in Fractional-Horsepower Motors
Transactions of the American Institute of Electrical Engineers, 1945THE revision of American Standard C50, “Rotating Electrical Machinery,” resulted in various suggestions for changing the method of measuring the temperature rise of motors and for establishing temperature-rise limits to be used with these methods. A review of the temperature tests taken in the past indicated that they are of little value for comparing ...

Tuning Temperature and Size of Hot Spots and Hot‐Spot Arrays
Small, 2010AbstractBy using scanning thermal microscopy, it is shown that nanoscale constrictions in metallic microwires deposited on an oxidized silicon substrate can be tuned in terms of temperature and confinement size. High‐resolution temperature maps indeed show that submicrometer hot spots and hot‐spot arrays are obtained when the SiO2 layer thickness ...

Hot spots of wheat yield decline with rising temperatures
Global Change Biology, 2016AbstractMany of the irrigated spring wheat regions in the world are also regions with high poverty. The impacts of temperature increase on wheat yield in regions of high poverty are uncertain. A grain yield–temperature response function combined with a quantification of model uncertainty was constructed using a multimodel ensemble from two key ...

Designing gradient coils with reduced hot spot temperatures
Journal of Magnetic Resonance, 2010Gradient coil temperature is an important concern in the design and construction of MRI scanners. Closely spaced gradient coil windings cause temperature hot spots within the system as a result of Ohmic heating associated with large current being driven through resistive material, and can strongly affect the performance of the coils.

Hot-Spot Temperatures in Dry-Type Transformer Windings
Transactions of the American Institute of Electrical Engineers, 1944With the increasing use of dry-type transformers, attention has been focused upon the fact that the difference between the average temperature rise by resistance and the hottest-spot temperature rise is much greater than in liquid-immersed transformers. In this paper there are given the results of an extended series of thermal tests on a variety of dry-
