Vacuum Breakdown: In the Townsend type of discharge in a gas described earlier, electrons get multiplied due to various ionization processes and an electron avalanche is formed. In a high Vacuum Breakdown, even if the…
V Shift and I Shift Method: V Shift and I Shift Method - A voltage source with a passive branch in series with it is called an accompanied voltage source. Similarly a current source with…
Uses of Ground Wave Propagation: Uses of Ground Wave Propagation along the surface of the earth and, as previously mentioned, must be vertically polarised to prevent short circuiting the electric component. A wave induces currents…
Uses of Computer and Microprocessor: Uses of Computer and Microprocessor - The first methods for solving various power system problems were AC and DC network analyzers developed in early 1930s. AC analyzers were used for…
Use of Power Capacitor: In most of the industrial applications, the power requirements are reactive in nature and a lagging current is drawn from the power lines. This requires additional generating capacity. This can be…
Use of Efficient Semiconductor Converters: Prior to development of Use of Efficient Semiconductor Converters, inefficient power modulators were employed in several applications. While replacement of these power modulators by the semiconductor converters in appropriate applications…
Use of Bundled Conductors in Transmission Line: A Bundled Conductors in Transmission Line is shown in Fig. 3.13. The conductors of any one bundle are in parallel, and it is assumed that the charge per…
Up Down Circuit Analysis: Any circuit has independent variables (such as source voltages and branch resistances) and dependent variables (such as voltage drop across resistors, current and power). Determination of response of dependent variables to…
Unsymmetrical Faults on Three Power System: Those faults on the power system which give rise to unsymmetrical fault currents (i.e. unequal fault currents in the lines with unequal phase displacement) are known as Unsymmetrical Faults…
Unsymmetrical Fault Analysis Interview Questions and Answers: 1. Draw the sequence network for single line-to-ground fault without fault impedance. Ans. 2. Draw the sequence network connections corresponding to L-L fault at a bus. Ans. 3.…
