Abstract:Purpose
To prevent the coil from burning or getting damaged, it is necessary to estimate the duration of its operation as long as its temperature does not exceed the permissible limit. This paper aims to investigate the effect of switching on the thermal behavior of impregnated and nonimpregnated windings. Also, the safe operating time for each winding is determined.
Design/methodology/approach
The power loss of the winding is expressed as a function of the winding specifications. Using homogenization techni… Show more
