Electrostatic Voltmeters: In Electrostatic Voltmeters fields, the attractive force between the electrodes of a parallel plate capacitor is given by where, V = applied voltage between plates, C = capacitance…
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…
AC Field Strength Meter: AC Field Strength Meter is usually measured by introducing a small fixed capacitance probe into the field area and measuring the induced charge on it. Since…
DC Electric Field Strength Meter: The DC Electric Field Strength Meter strength E can be measured by using (i) variable capacitor probe or generating voltmeter or (ii) a vibrating plate…
Generating Voltmeter Principle and Construction: High voltage measuring devices employ generating principle when source loading is prohibited (as with Van de Graaff generators, etc.) or when direct connection to the…
Tripping of Impulse Generator: In large impulse generator, the spark gaps are generally sphere gaps or gaps formed by hemispherical electrodes. The gaps are arranged such that sparking of one…
Generation of Impulse Current Generator Output Waveform: Lightning discharges involve both high voltage impulses and high current impulses on transmission lines. Protective gear like surge diverters have to discharge the…
