Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter as shown in Fig. 7.1. Only the current I flowing through the…
3 Phase Delta Connection: Delta Connected System - Figure 9.26 shows a balanced three-phase, three-wire, delta-connected system. This arrangement is referred to as mesh connection because it forms a closed circuit. It is also known…
Tidal Power Plant - Types and Working Principle: Introduction to tidal power plant - Gravitational force between the moon, the sun and the earth causes the rhythmic rising and lowering of ocean water, around the…
Introduction to Overhead Line: Electric power can be transmitted or distributed either by means of underground cables or by overhead line. The underground cables are rarely used for power transmission due to two main reasons.…
Capacitance of a Single Phase Two Wire Line: Consider a Capacitance of a Single Phase Two Wire Line consisting of two parallel conductors A and B spaced d metres apart in air. Suppose that radius…
Finite Impulse Response Filters Interview Questions and Answers: 1. What are the different types of filters based on impulse response? Ans. Based on impulse response the filters are of two types 1. IIR filter 2.…
Dynamic Characteristics: Instruments rarely respond instantaneously to changes in the measured variables. Instead, they exhibit slowness or sluggishness due to such things as mass, thermal capacitance, fluid capacitance or electric capacitance. In addition to this,…
Hydel Power Plant - Definition, Working Principle and Advantages: Power of water - Hydel Power Plant is a clean and cheap source of energy. The basic principle of hydropower is that when water is piped from…
Ward Leonard Method of Speed Control: Known after the name of its inventor Ward Leonard Method of Speed Control (1891), it consists of a separately excited generator feeding the dc motor to be controlled. The…
Circuit Constants of a Transmission Line: In any four terminal network, the input voltage and input current can be expressed in terms of output voltage and output current. Incidentally, a Circuit Constants of a Transmission…
