Slip Power Recovery Scheme used in Induction Motor: Slip Power Recovery Scheme used in Induction Motor - Figure 6.53 shows an equivalent circuit of a wound-rotor induction motor with voltage Vr injected into its rotor,…
Direct Coupled Circuits: For economy, the number of components used in any circuit should be kept to a minimum. The use of direct coupling between stages is one way of eliminating components. Figure 12-20 shows…
Control Signals of 8085: The 8085 Microprocessor provides RD and WR signals to initiate read or write cycle. Because these Control Signals of 8085 are used both for reading/writing memory and for reading/writing an input…
Switching Surges in Transmission Line: Till the time when the transmission voltages were about 220 kV and below, over-voltages due to lightning were of very high order and overvoltages generated inside the system were not…
Ward Leonard Method of Speed Control of DC Motor: Ward Leonard Method of Speed Control of DC Motor is combined armature and field control and is therefore, operationally the most efficient method of speed control…
Second Order High Pass Butterworth Filter Derivation: As in the case of a first order filter, a second order high pass filter can be formed from a second order low pass filter by simply interchanging…
Steady State Stability in Power System: The steady state stability limit of a particular circuit of a power system is defined as the maximum power that can be transmitted to the receiving end without loss…
Short Circuit kVA: Although the potential at the point of fault is zero, it is a normal practice to express the short-circuit current in terms of Short Circuit kVA based on the normal system voltage…
What is Schottky Diode? - Definition, Symbols and Construction: At lower frequencies, an ordinary diode can easily turn off when the bias changes from forward to reverse. But with the increase in frequency the diode…
Source Transformation Technique: Source Transformation Technique - In solving networks to find solutions one may have to deal with energy sources. It has already been discussed before that basically, energy Source Transformation are either voltage…
