Heterodyne Wave Analyzer: Wave analyzers are useful for measurement in the audio frequency range only. For measurements in the RF range and above (MHz range), an ordinary wave analyzer cannot be used. Hence, special types…
Newton Raphson Method for Load Flow Analysis: The Newton Raphson Method for Load Flow Analysis is a powerful method of solving non-linear algebraic equations. It works faster and is sure to converge in most cases…
DC Load Line Analysis of Semiconductor Diode: Figure 2-13(a) shows a DC Load Line Analysis of Semiconductor Diode in series with a 100 Ω resistance (R1) and a supply voltage (E). The polarity of E is…
Pulse and Square Wave Generator Block Diagram (Laboratory Type): Pulse and Square Wave Generator are used as measuring devices in combination with a CRO. They provide both quantitative and qualitative information of the system under…
Bad Data Detection in State Estimation of Power System: The ability to identify Bad Data Detection in State Estimation measurements is extremely valuable to a load dispatch centre. One or more of the data may…
Current Source Inverter Fed Synchronous Motor Drive: A synchronous motor draws a stator current which is independent of stator frequency when V/f and E/f are maintained constant and armature resistance is neglected. The motor also…
Requirements of Satisfactory Electric Supply Connection: The Electric Supply Connection in India is 3-phase a.c. operating at a frequency of 50 Hz. The power station delivers power to consumers through its transmission and distribution systems.…
Four Phase Stepper Motor: Four Phase Stepper Motor - The stepper motor is a special type of synchronous motor which is designed to rotate through a specific angle (called a step) for each electrical pulse…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances. It is the purpose of…
La Mont Boiler Construction and Working: This type of boiler was introduced by Lamont in 1925. The arrangement of La Mont Boiler Construction and Working is shown in the Fig. 1.30. It is a forced…
