Deltatron Circuit or Cascaded Modular Voltage Multipliers: A combination of Cockcroft-Walton type voltage multiplier with cascaded transformer d.c. rectifier is developed recently for very high voltages but limited output currents having…
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…
Pure Liquids and Commercial Liquids: Pure liquids are those which are chemically pure and do not contain any other impurity even in traces of 1 in I09, and are structurally…
Characteristics of Liquid Dielectrics: Essential Characteristics of Liquid Dielectrics should possess good dielectric properties, excellent heat transfer characteristics and must be chemically stable under the range of conditions under which the…
Corona Discharges: If the electric field is uniform, a gradual increase in voltage across a gap produces a breakdown of the gap in the form of a spark without any…
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…
Protection of Transformers: Transformers are static devices, totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However, the consequences of even a rare…
