Different Types of High Voltages: In the fields of electrical engineering and applied physics, Different Types of High Voltages (d.c., a.c,, and impulse) are required for several applications. For example,…
Applications of Cables in Engineering Works: In the recent years natural rubber has been completely replaced by synthetic rubbers and plastics as cable insulation. The physical properties required for wire…
Applications of Rotating Machines: Applications of Rotating Machines are normally divided into two categories: those with voltage ratings less than 6,600 V are called low voltage machines, and the others…
Applications of Power Transformers: Transformers are the first to encounter lightning and other high voltage surges. The transformer insulation has to withstand very high impulse voltages many times the power…
Insulating Materials Types: There is no piece of electrical equipment that does not depend on electrical insulation in one form or an other to maintain the flow of electric current…
High Temperature High Performance Polymers: High Performance Polymers films are thermoplastic and are generally transparent. The are needed for use in applications where temperatures vary from very low (- 269°C)…
Solid Dielectrics Used in Practice: The majority of the insulating systems used in practice are solids. They can be broadly classified into three groups: organic materials, inorganic materials and synthetic…
Breakdown in Composite Dielectrics: It is difficult to imagine a complete insulation system in an electrical equipment which does not consist of more than one type of insulation. If an…
