Types of Electrical Drives: Types of Electrical Drives has the following major parts: load, motor, power modulator, control unit and source. There are large number of loads and each load…
Characteristics of Synchronous Motor: Characteristics of Synchronous Motor are constant speed motors. The speed of the motor is decided by the number of poles and frequency. Compared to an induction…
Torque Speed Characteristics of Induction Motor: From Eq. 1.27 it can be observed that the maximum torque is independent of rotor resistance. However, the slip at which the maximum torque…
Heat Capacity of Calorimeter: Heat Capacity of Calorimeter - RF power may be directly converted into heat. Water acts as the load, and RF power may be used to heat…
A Simple Electric Motor: Variable speed drives in the industry employ a simple electric motor as their drive motors mainly because they enjoy several specific advantages, such as overload capacity,…
Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive…
Mathematical Formulation of Voltage Stability: Mathematical Formulation of Voltage Stability - The slower forms of voltage instability are normally analyzed as steady state problems using power flow simulation as the…
Derivation of Transmission Loss Formula: An accurate method of obtaining a general derivation of transmission loss formula has been given by Kron. This, however, is quite complicated. The aim of…
