Capability Curve of Synchronous Generator: Capability Curve of Synchronous Generator defines the bounds within which it can operate safely. Various bounds imposed on the machine are: MVA-loading cannot exceed the generator rating. This limit is…
Second Order Low Pass Butterworth Filter: The practical response of Second Order Low Pass Butterworth Filter must be very close to an ideal one. In case of low pass filter, it is always desirable that…
Carbon Arc Welding - Working Principle, Advantages and Applications: Carbon arc welding differs from metal arc welding in that it is a puddling process and is somewhat similar to the gas welding process. The carbon…
Resonant Coaxial Wavemeter: A Resonant Coaxial Wavemeter line such as illustrated in Fig. 16.1 and operating as a resonant system can be used to measure frequencies in the range of 600 — 10,000 MHz. At…
Frequency Generating Transducer: Frequency Generating Transducer - Unlike variable parameter analog transducers, frequency and pulse generating transducers measure physical variables in terms of a pulse repetition rate. Since frequency is an analog quantity, these can…
Nodal Analysis Examples: Nodal Analysis Examples - we discussed simple circuits containing only two nodes, including the reference node. In general, in a N node circuit, one of the nodes is chosen as reference or…
DC Motor Electric Brakes: DC Motor Electric Brakes - While operating electrical drives it is often necessary to stop the motor quickly and also reverse it. In applications like cranes or hoists the torque of…
Direct Testing of Circuit Breaker: The Direct Testing of Circuit Breaker in a plant enables us to test under conditions largely representing those in actual network as well as tests of greater severity. The circuit…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are increased. The increase in the…
Dielectric Constant and Loss: Many insulating substances have dielectric constant greater than unity and have Dielectric Constant and Loss when subjected to a.c. voltages. These two quantities, namely, the dielectric constant and the loss depend…
