Impulse measurements using Multiple Shield Enclosures and Signal Cable: Multiple Shield Enclosures - It is essential that leads, layout, and connections from the signal sources to the CRO are to be…
Cascade Transformer Connection: Figure 6.10 shows the Cascade Transformer Connection units in which the first transformer is at the ground potential along with its tank. The second transformer is kept…
Low Voltage Arms for Voltage Divider: Low Voltage Arms for Voltage Divider - The mode of connection and the layout arrangement of the secondary arm of the divider is very…
Magnetic Type Potential Transformer: Magnetic Type Potential Transformer are the oldest devices for a.c, measurements. They are simple in construction and can be designed for any voltage. For very high…
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…
Breakdown of Solid Dielectrics in Practice: There are certain types of breakdown which do not come under either intrinsic breakdown or thermal breakdown, but actually occur after prolonged operation. These…
