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…
Uniform Field Electrode Gaps: Sphere gaps, although widely used for voltage measurements, have only limited range with Uniform Field Electrode Gaps. Hence, it is not possible to ensure that the…
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…
Applications in Circuit Breaker: Applications in Circuit Breaker : A circuit breaker is a switch which automatically interrupts the circuit when a critical current or voltage rating is exceeded. A.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…
Equipments in Transformer Substation: The Equipments in Transformer Substation depends upon the type of sub-station, service requirement and the degree of protection desired. However, in general, the Equipments in Transformer…
Surge Diverter | Lightning Arrester Types: The earthing screen and ground wires can well protect the electrical system against direct lightning strokes but they fail to provide protection against travelling…
Types of Lightning Strikes: There are two Types of Lightning Strikes may strike the power system (e.g. overhead lines, towers, sub-stations etc.), namely; Direct stroke Indirect stroke 1. Direct stroke:…
