What is power factor write its significance?
Power factor is the measure of evaluating how effectively the incoming electrical power is used in an electrical system. If the power factor is high, then we can say that more effectively the electric power is being used in an electrical system.
What is the real world purpose of a power factor?
A typical distribution system is limited in the amount of current it can carry; power factor, expressed as a percentage, is an indicator of the amount of total current that can be used to create work (active power). The closer the power factor is to 1.00 (100\%), the lower the amount of current needed to do said work.
What is the significance of power factor explain it with the help of power triangle?
Power Factor is defined as the cosine of an angle between the current and voltage. Otherwise, the ratio between the real power to reactive power is called power factor. Unit: Since power factor is a ratio quantity, that’s why it does not have any units.
What is significance of voltage and reactance triangle?
Explanation of Impedance Triangle: Therefore, it can be expressed in these two components. Let the impedance of an alternating current circuit is Z = R+jX where R and X represents the resistance and reactance. Hence, Impedance Triangle helps us to find the magnitude as well as the angle of impedance of a circuit.
What does power triangle and impedance triangle mean?
When building an impedance or power triangle, the resistive component always goes on the bottom of the triangle and the reactive component always goes on the side.
How can an industry improve the power factor?
You can improve power factor by adding power factor correction capacitors to your plant distribution system. When apparent power (kVA) is greater than working power (kW), the utility must supply the excess reactive current plus the working current . Power capacitors act as reactive current generators .
