Optimal Scheduling of Hydrothermal Processes: The earlier sections have dealt with the problem of optimal scheduling of a power system with thermal plants only. Optimal operating policy in this case can be completely determined at…
Optimal Operation of Generators on a Bus Bar: Optimal Operation of Generators on a Bus Bar - The major component of generator operating cost is the fuel input/hour, while maintenance contributes only to a small…
Optimal Load Flow Solution: The problem of optimal real power dispatch has been treated in the earlier section using the approximate loss formula. This section presents the more general problem of real and reactive power…
Optical Pyrometer Working Principle: Optical Pyrometer Working Principle - Any metallic surface when heated emits radiation of different wavelengths which are not visible at low temperature but at about 550 °C, radiations in shorter wavelength…
Optical Fiber Classification: The Optical Fiber Classification of light transmission through a glass fiber depend on many factors, for example: The composition of the fiber The amount and type of light introduced into the fiber…
Optical Encoders: The Optical Encoders are used to get the information about the position, direction of rotation, and speed of rotation of various motor shafts. They provide this information in digital form which can easily…
Optical Absorption in Electronics: As discussed in Art. 25.3, light waves can be treated as particles, which are referred to as photons. The energy of a photon is E = hf where h is Plank's…
Operations of Traction Power Controller (TPC): It is provided to have a comprehensive picture of supply conditions and arrangement to operate switchgear with minimum delay so that continuity of electric supply to the track, which…
Operational Transconductance Amplifier (OTA) Interview Questions and Answers: 1. What is OTA ? Ans. OTA stands for operational transconductance amplifier which is a specially designed single chip voltage input, current output amplifier. 2. Give the applications…
Operational Transconductance Amplifier (OTA): The operational amplifiers considered up to this point have been voltage amplifiers. The input signal is a voltage and the output signal is a voltage. Another type of op-amp is an…
