Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter as shown in Fig. 7.1. Only the…
Generation of Switching Surges: Nowadays in extra high voltage transmission lines and power systems, switching surges is an important factor that affects the design of insulation. All transmission lines rated…
Series Inductance in Impulse Generator Circuit: Often Series Inductance in Impulse Generator Circuit are required to test equipment with large inductance, such as power transformers and reactors. Usually, generating the…
Generation of High Frequency AC High Voltage: High Frequency AC High Voltage are required for rectifier d.c power supplies. Also, for testing electrical apparatus for switching surges, High Frequency AC…
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…
Voltage Drop on Load and Regulation: The change of average Voltage Drop on Load from the no load theoretical value expressed as a percentage of no load voltage is called…
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…
