Definite Distance Type Impedance Relay: Fig. 21.21 shows the schematic arrangement of a Definite Distance Type Impedance Relay. It consists of a pivoted beam F and two electromagnets energized respectively by a current and voltage…
Light Wave Spectrum: Light Wave Spectrum - In everyday terms, light can be defined as the pail of the visible spectrum that has a wavelength range between 0.4 μm (micrometer) and 0.7 μm (refer to…
Extensions of Single Sideband Amplitude Modulation: The Extensions of Single Sideband Amplitude Modulation is namely, Forms of Amplitude Modulation: This section on amplitude modulation defines, describes and lists the main applications of the various forms of…
LM335 IC Temperature Sensor: LM335 IC Temperature Sensor - IC sensor produces a voltage or current signal that increases with increase in temperature. It eliminate the linearity errors associated with thermistor. However, being semiconductor devices,…
High Pressure Mercury Vapour Lamp - Construction and Working: The extensive use of the mercury vapour lamp depends entirely upon the versatility of the mercury vapour as regards pressure, temperature, voltage and other characteristics, each…
Important Definition of Phase Locked Loop (PLL): Some Important Definition of Phase Locked Loop PLL are as follows : Lock Range: When PLL is in lock, it can track frequency changes in the incoming signal.…
Polar Curve in illumination | Rousseau's Construction: Polar Curve in illumination - All discussions made so far were based on the assumption that the luminous intensity or the candle power from a source is uniformly…
Collision Process in Gases: An electrical discharge is normally created from unionised gas by Collision Process in Gases. These processes are mainly gas processes which occur due to the collision between the charged particles and…
Balanced Earth Fault Protection: In small-size alternators, the neutral ends of the three-phase windings are often connected internally to a single terminal. Therefore, it is not possible to use Merz-Price circulating current principle described above…
Three Phase Balanced Circuit: The analysis of Three Phase Balanced Circuit is presented in this section. It is no way different from the analysis of AC systems in general. The relation between voltages, currents and…
