Difference Between Current Transformer (CT) and Potential Transformer

Electrical Engineering Interview Questions And Answers On Transformers - Questions & Answers. In these transformer only one winding is used as primary and secondary. This color wire is a secondary live wire in a 220 volt circuit and used in some types of interconnection.

The term static indicates that it does not contain any rotating part in it. When an alternating voltage is applied to one winding (called the primary), it sets up alternating flux in the core. (c) either of the above. This color wire is a secondary live wire in a 220 volt circuit and used in some types of interconnection. The alternating flux links the other winding. Transformer is a static electrical device which transfers power from one circuit to another circuit without any physical contact. Introduction to electrical engineering interview questions and answers. List the rated current in the secondary. The main aim of this transformer is that the output power of the transformer is same as output power. Hysteresis loss is a heat loss caused by the magnetic properties of the armature.

(c) either of the above. The main aim of this transformer is that the output power of the transformer is same as output power. Reduction in core losses and increase in permeability are obtained with transformer employing. When the armature core is rotating, its magnetic field keeps. What is the principle of operation of a transformer ? Hysteresis loss is a heat loss caused by the magnetic properties of the armature. An alternator converts mechanical energy into ac electrical energy, a generator converts it to ac or dc. In this article, we provide a list of commonly asked interview questions for electrical engineers and provide a few sample answers to review. When an armature core is in a magnetic field, the magnetic particles of the core tend to line up with the magnetic field. Introduction to electrical engineering interview questions and answers. Electric traction means using the electric power for traction system (i.e.
