Different Types of High Voltages: In the fields of electrical engineering and applied physics, Different Types of High Voltages (d.c., a.c,, and impulse) are required for several applications. For example, electron microscopes and x-ray units…
Interference in Telecommunication Circuit in Electric Traction: In all traction systems track is used as a return path for the current. Some part of the current flows through the track and the remaining portion of…
Half Wave Rectifier Circuit: A basic diode Half Wave Rectifier Circuit is shown in Fig. 3-1(a). An alternating input voltage is applied to a single diode connected in series with a load resistor RL. The…
Reversible Drives using Choppers: Using two quadrant choppers a reversible drive can be achieved, because this combination allows reversal of both current and voltage of the motor termiÂnals. We can get a regenerative reversible drive.…
Dynamical Equations of Electromechanical Systems: Dynamical Equations of Electromechanical Systems - Figure 4.19 shows an electromagnetic relay whose armature is loaded with spring K, damper B, mass M and a force generator F. Figure 4.20…
Single Line to Ground Fault: Figure 11.4 shows a Single Line to Ground Fault at F in a power system through a fault impedance Zf. The phases are so labelled that the fault occurs on…
Radar Performance Factors: Quite apart from being limited by the curvature of the earth, the maximum range of a radar Set depends on a number of other Radar Performance Factors. These can now be discussed,…
Double Line to Ground Fault (LLG): Figure 11.9 shows a Double Line to Ground Fault at F in a power system. The fault may in general have an impedance Zf as shown. The current and…
Fluidized Bed Combustion Boiler Working and Types: The coal available in India is of low quality, high ash content and low calorific value. The traditional grate fuel firing systems have got limitations and are techno-economically…
Continuous Duty Motor: There are two types of Continuous Duty Motor — continuous duty at constant load and continuous duty with variable load cycle. In the former the load torque remains constant for a sufficiently longer…
