Two Hole Directional Coupler: It is often necessary to measure the power being delivered to load or an antenna through a transmission line. This is often done by a sampling technique, in which a known…
Two Diode Full Wave Rectifier Circuit: The Fig. 3-2 shows the Two Diode Full Wave Rectifier Circuit, and its input voltage is supplied from a transformer (T1) with a center-tapped secondary winding. The circuit is…
Two Dimensional Motion in a Uniform Electric Field: Two Dimensional Motion in a Uniform Electric Field - Let us consider that an electron enters the region between two parallel plates of a parallel plate capacitor…
Two Area Load Frequency Control: Two Area Load Frequency Control - An extended power system can be divided into a number of Two Area Load Frequency Control areas interconnected by means of tie lines. Without…
Twigs and Links: Twigs and Links - The branches of a tree are called its 'twigs'. For a given graph, the complementary set of branches of the tree is called the co-tree of the graph.…
Twelve pulse converter: It is clear from the preceding discussion that increasing the pulse number to six greatly improves the performance of the converter. The ac line current has only odd harmonics and the value…
TV Video Waveform: Blanking - TV Video Waveform voltage is limited to certain amplitude limits. Thus, for example, the white level corresponds to 12.5 percent (±2.5 percent) modulation of the carrier, and the black level…
TV Receiver Synchronizing Circuits: The task of the TV Receiver Synchronizing Circuits is to process received information, in such a way as to ensure that the vertical and horizontal oscillators in the receiver work at…
Turgo Turbine Working Principle: The Turgo turbine is an impulse water turbine designed for medium head applications. Operational Turgo Turbines achieve efficiencies of about 87%. It works with net heads between 15 and 300 m.…
Turbocompressors: The turbocompressors and blowers in the industry require drives rated up to 40 MW. Drives of large rating are also required in steel industry blast furnace blowers in natural gas pipelines and liquefaction processes…
