Difference between Static Relays and Electromagnetic Relays: The conventional electromagnetic relays are robust and quite reliable, but are required to operate under different forces under fault conditions. This leads to delicate setting small contact gaps,…
Structure of Power Systems: Structure of Power Systems - Generating stations, transmission lines and the distribution systems are the main components of an electric power system. Generating stations and a distribution system are connected through…
Magnetically Induced Emf and Force: Magnetically Induced Emf and Force - Faraday's law of induction, which is the integral form of the fourth Maxwell's equation, is given as The integrated form of Eq.(2.15) for a…
Two pulse bridge converter: A two pulse bridge converter is achieved as shown in Fig. 3.22 from two midpoint converters. They are connected in series on the dc side and in parallel on the ac…
Stepper Motor Interface: A stepper motor is a digital motor. It can be driven by digital signal. Fig. 15.18 shows the typical 2 phase Stepper Motor Interface using 8255. Motor shown in the circuit has…
Development of Electric Power Industry: The basic human need for safe, efficient, and affordable light became the driving force which led to the Development of Electric Power Industry of today's continent-spanning electric energy or power…
IC Waveform Generators Interview Questions and Answers: 1. What is an oscillator? Ans. Oscillator may be defined as a circuit which generates an ac output signal of very high frequency without requiring any externally applied input…
Induction Type Overcurrent Relay(Non-Directional): This Induction Type Overcurrent Relay works on the induction principle and initiates corrective measures when current in the circuit exceeds the predetermined value. The actuating source is a current in the…
Boundary Element Method (BEM) in Electric Field: Though the charge simulation method is known for its accuracy and speed, it is not very efficient in case of multi-dielectric problems and very thin electrodes, which are…
Stroboscope Working Principle: The stroboscope working principle uses a high intensity light which flashes at precise intervals. This light may be directed upon a rotating or vibrating object. The stroboscopic effect is apparent when the…
