Measurement of Power Articles: Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a…
Low Ohmic Shunt: The most common method employed for high impulse current measurements is a Low Ohmic Shunt shown in Fig. 7.46. The equivalent circuit is shown in Fig. 7.46b.…
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…
Formative Time Lag: Formative Time Lag - In the previous section, the mechanism of spark breakdown is considered as a function of ionization processes under uniform field conditions. But in…
Experimental Arrangement to Measure Ionization Coefficients α and γ: The Experimental Arrangement to Measure Ionization Coefficients is shown in Fig. 2.2. The electrode system consists of two uniform field electrodes. The…
Ionization Processes: A gas in its normal state is almost a perfect insulator. However, when a high voltage is applied between the two electrodes immersed in a gaseous medium, the…
Corona: When an alternating potential difference is applied across two conductors whose spacing is large as compared to their diameters, there is no apparent change in the condition of atmospheric…
Stepper Motor Applications: The microprocessors are employed for the control of stepper motors which are generally used as position actuators. Some other Stepper Motor Applications are to drive floppy discs,…
