Factors Influencing the Sparkover Voltage of Sphere Gaps: Various factors that affect the sparkover voltage of a sphere gap are: nearby earthed objects, atmospheric conditions and humidity, irradiation, and polarity…
Sphere Gaps are used to measure Voltage Measurement: Sphere Gaps are used to measure Voltage Measurement - A uniform field spark gap will always have a sparkover voltage within a…
Capacitance Voltage Transformer: The errors due to harmonic voltages can be eliminated by the use of capacitive voltage dividers with an electrostatic voltmeter or a high impedance meter such as…
Multistage Impulse Generator Circuit: In the early discussion, the generator capacitance C1 is to be first charged and then discharged into the wave shaping circuits. A single capacitor C1 may…
Series DC Voltage Regulator: The output voltage of a d.c. source, whether it is a rectifier or any other machine, changes with the load current as well as with the…
Electrostatic Generators: Van de Graaff generators are essentially high voltage but low power devices, and their power rating seldom exceeds few tens of kilowatts. As such Electrostatic Generators machine which…
Applications in High Voltage Bushings: At rated voltages higher than 52 kV, the condenser or capacitance graded bushing principle is generally used. The insulating material for such a Applications in…
