Resistance Heating - Types, Advantages and Applications: Resistance heating is based upon the I2R effect. This method of heating has wide applicaÂtions such as heat treatment of metals (annealing, hardenÂing etc.), drying and baking of…
Resistance Grounding: In order to limit the magnitude of earth fault current, it is a common practice to connect the neutral point of a 3-phase system to earth through a resistor. This is called Resistance…
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.…
Requirements of a Distribution System: A considerable amount of effort is necessary to maintain an electric power supply within the requirements of various types of consumers. Some of the good Requirements of a Distribution System…
Repulsion Start Induction Motor - Working Principle: As the name implies, the repulsion-start induction motor starts as a repulsion motor and runs as an induction motor. The general construction of a repulsion-start inducÂtion motor is…
Repulsion Motor - Construction, Working Principle and Applications: The characteristics of repulsion motors are similar to those of a series motor, i.e., high startÂing torque and high light-load speed. Its construction is also similar to…
Repulsion Induction Motor - Construction, Working Principle and Applications: The repulsion induction motor has a single phase stator winding, as a repulsion-start induction motor has, but it has two separate and independent windings on rotor…
Representation of Power System Components Interview Questions and Answers: 1. What is meant by percentage reactance ? Ans. Percentage reactance can be defined as the voltage drop across the given reactance expressed as percentage of…
Reluctance Pulse Pick up Transducer: This Reluctance Pulse Pick up Transducer is very suitable for the measurement of shaft speed and liquid flow. It is based on the principle that if the field of any…
Reliability Consideration in Power System: With the increasing dependence of industry, agriculture and day-to-day household comfort upon the continuity of electric supply, the Reliability Consideration in Power System has assumed great importance. Every electric utility…
