Question
A motor load consumes both active and reactive power. If the power consumed by
motor is represented by power triangle. The hypotenuse of the power triangle
represents
Answers
Answer:
We know that reactive loads such as inductors and capacitors dissipate zero power, yet the fact that they drop voltage and draw current gives the deceptive impression that they actually do dissipate power.
This “phantom power” is called reactive power, and it is measured in a unit called Volt-Amps-Reactive (VAR), rather than watts.
The mathematical symbol for reactive power is (unfortunately) the capital letter Q.
Answer:
Reactive power, and it is measured in a unit called Volt-Amps-Reactive (VAR), rather than watts.
Explanation:
Power Triangle is the representation of a right angle triangle showing the relation between active power, reactive power and apparent power. When each component of the current that is the active component (Icosϕ) or the reactive component (Isinϕ) is multiplied by the voltage V, a power triangle. The power which is actually consumed or utilized in an AC Circuit is called True power or Active Power or real power. It is measured in kilowatt (kW) or MW.
The power which flows back and forth that means it moves in both the direction in the circuit or reacts upon it, is called Reactive Power. The reactive power is measured in kilovolt-ampere reactive (kVAR) or MVAR.
The product of root mean square (RMS) value of voltage and current is known as Apparent Power. This power is measured in KVA or MVA.
The following point shows the relationship between the following quantities and is explained by graphical representation called Power Triangle.
