ACSR Conductor (Aluminium Conductor Steel Reinforced): ACSR Conductor - So far we have considered transmission lines consisting of single solid cylindrical conductors for forward and return paths. To provide the necessary flexibility for stringing, conductors…
Darlington Connected Output Transistors: High-power transistors usually have low current gains, so relatively large base currents must flow into Q2 and Q3 to supply a high load current. This means that the quiescent current through…
Phase Relation in Pure Resistor: Phase Relation in Pure Resistor - When a sinusoidal voltage of certain magnitude is applied to a resistor, a certain amount of sine wave current passes through it. We know…
Projection Welding - Definition, Working, Advantages and Applications: Projection welding is a resistance welding process that produces coalescence by the heat obtained from the resistance to the flow of the welding current. The resulting welds…
Basic Elements of Digital Communication System: Figure 23.3 shows the functional diagram and the basic elements of digital communication system. The source output may be either an analog signal like audio or video signal, or…
Power System Security Analysis: Power System Security Analysis can be broken down into two major functions that are carried out in an operations control centre: Security assessment, and Security control. The former gives the security…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the strength of the line should…
Various Systems of Power Transmission: It has already been pointed out that for transmission of electric power, 3-phase, 3-wire a.c. system is universally adopted. However, other systems can also be used for transmission under special…
Lithography Process in IC Fabrication: Lithography Process is used to produce a multiple image on the resists which covers the wafer. A Lithography Process in IC Fabrication can be realised with the help of three…
Precision Rectifiers: Recall from basic circuit principles that a rectifier circuits can be implemented with a diode/diodes (half wave rectifier or full wave rectifier). The major limitations of these Precision Rectifiers circuits is that they…
