Instrumentation Amplifier or Data Amplifier: Instrumentation Amplifier - Many industrial systems, consumer systems and process control systems require a precise measurement of the physical quantities like temperature, pressure, humidity, weight etc. A sugar factory requires…
Speed Torque Characteristics of DC Series Motor: To find the Speed Torque Characteristics of DC Series Motor, let us analysis the figure 7.43 shows the connection diagram of a dc series motor. The speed for…
Paschen Breakdown | Paschen's Law | Paschen curve It has been shown earlier (refer Sec. 2.6) that the Paschen Breakdown criterion in gases is given as where the coefficients α and γ are functions of E/p, i.e…
Sequential Circuits: There are many applications in which digital outputs are required to be generated in accordance with the sequence in which the input signals are received. This requirement cannot be satisfied using a combinational…
Operating Modes of 8257: The Operating Modes of 8257 can be programmed to operate in following modes : Rotating Priority Mode : In rotating priority mode, the priority of the channels has a circular sequence.…
Impulse Voltage Test System: It is extremely difficult to control and adjust the Impulse Voltage Test System wave shapes for different load conditions as in the case of large capacitive loads, very low inductors or…
Operation of UHV Laboratory: Operation of UHV Laboratory are designed as indoor laboratories or outdoor laboratories depending on the specific requirements. An indoor laboratory is preferred when most of the equipment testing and associated research…
Earth Fault Protection or Leakage Protection: An Earth Fault Protection usually involves a partial breakdown of winding insulation to earth. The resulting leakage current is considerably less than the short-circuit current, The Earth Fault Protection…
Field Oriented Control of Three Phase Induction Motor: The stator current of an induction motor has the functions of producing the required air gap flux (magnetisation) as well as developing the required torque to drive…
Energy Conservation Methods: Energy Conservation Methods is the cheapest new source of energy. We should resort to various conservation measures such as cogeneration (discussed earlier), and use energy efficient motors to avoid wasteful electric uses.…
