Voltage Multiplier Circuits: Cascaded Voltage Multiplier Circuits for higher voltages are cumbersome and require too many supply and isolating transformers. It is possible to generate very high d.c. voltages from…
Voltage Doubler Circuits: Both full wave and half wave rectifier circuits produce a d.c. voltage less than the a.c. maximum voltage. When higher d.c voltages are needed, a Voltage Doubler…
Half and Full Wave Rectifier Circuits: Half and Full Wave Rectifier Circuits for producing high d.c. voltages from a.c. sources may be (a) Half wave, (b) Full wave, or (c) Voltage…
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.…
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…
Conduction and Breakdown in Commercial Liquids: As already mentioned, Conduction and Breakdown in Commercial Liquids are not chemically pure and have impurities like gas bubbles, suspended particles, etc. These impurities…
