The paper deals with the history of the early period of development of one- and three-phase transformers, an ingenious instrument invented in the XIX century. This article focuses on the transformers in a power system but the principles and the structure that governs the function of this device are the same, regardless of a size or application. The oldest constructions of the so-called inductors and...
The paper investigates an improved approach to the method for separation of no-load losses in the induction motor. The effect of influence of voltage on mechanical loss is developed - e.g. as a result of the interaction between the radial unbalanced magnetic pull and voltage. The effect of occurrence of asynchronous torques due to higher harmonics and their influence on the measurement of mechanical...
