Transformers are devices used to transfer power between two AC circuits. It works on Faraday’s Law of electromagnetic induction. In all transformers except auto-transformers electric power is transferred from one circuit to another by a common magnetic field produced. When an alternating current is ...

In this paper, two different piezoelectric transformers have been studied and compared: a Rosen type and a radial mode type. The first approach consists in performing an analytical model. This approach is inspired by the technique used in electroacoustics and allows to build an electric equivalent ...

relays. Protective relays continuously monitor these parameters: voltage, current, and power; and if these parameters violate set limits they generate an alarm or isolate that particular circuit. These types of relays are used to protect equipment like motors, generators, andtransformers, and so on...
apower transformers are important and expensive equipment in electric energy networks. The majority of these devices have been in service for many years under different environmental, electrical, and mechanical conditions. In addition to the costs associated with equipment repair or replacement, the capit...
These types of batteries are now extensively used in Electric Vehicles likeTesla Cars. Li-Po (Lithium Polymer) Batteries The next evolution of rechargeable battery technology is the Lithium Polymer Battery.Lithium Polymer or LiPo batteries are a great new way of storing energy for portable devices ...
2.2. Role of energy storage systems Breakthroughs that dramatically reduce the costs of electricity storage systems could drive revolutionary changes in the design and operation of the electric power system [52]. Peak load problems could be reduced, electrical stability could b...
