Hello engineers you are reading the post of electrical Zindagi it's a part of Shri Radhe studies

 Friends, if you are also from electrical background, then today's post is going to be very important for you because in today's post we are going to talk about power factor.

We will talk about power factor in many questions above.

 Questions covered in this post

•  What is power factor?

In today's post we are going to talk about many questions and many doubts, so read this post till the end and share it with your friends as well.

 Friends, electrical power is very important in today's time, whether it is AC (Alternating current) electrical power or DC (Direct Current) electrical power, both are playing an important role in their place.

 You know that AC generates energy, we transmit electricity in AC itself and also distribute and utilize AC electricity.

The most important thing in such a condition is that we save our electrical energy from being wasted so that we can utilize our electrical energy completely.

 Friends, it has been seen in many cases that due to improper power factor of a machine or factory or a house for domestic purpose, it uses more electricity than its requirement and does not give its equal output as a result, then such a condition occurs.  we count in wastage of electricity

 In today's post, we are going to talk about the most demanded topic power factor in electrical engineering, we will talk about many questions

 Friends, if you are from engineering background, MCQs related to power factor or small and big questions such as how power factor improvement can be done or whether it is good to have more power factor or it is good to be less, many such power factor related questions are usually asked from you.  But they are asked in the interviewer or exam, I claim that after reading this post today, you will not miss any question related to power factor.

Definition of Power Factor

 power factor definition:

 The angle between voltage and current in an electrical system is called the power factor, denoted by Cos¢.

 "The cosine of angle between voltage and current in an a.c. circuit is known as Power Factor"

 P=VICOS¢

 P = Power

 V=Voltage

 I = Current

 Cos ¢ = Power factor

 ¢ = Angle between current and voltage

 power factor explanation

 3 types of load are considered in electrical, resistive load, inductive load and capacity load, out of which we usually get to see resistive load and inductive load.

Normally we do not get to see the capacity load, this is the main reason that the current leading power factor is not comparably to the voltage in the power factor. If I speak in simple language, I can tell you that 98 out of 100 in the electrical system  The percentage you will get to see the legging power factor, we will talk about it in the next article.

Friends, before talking further, I would like to give you a piece of information as you know that when a load is connected to a supply, in such a condition both the voltage and current from the supply to the load reach in a wave, in such a condition the voltage and current  The webforms of both are different, now normally it should be that the webforms of current and voltage start together and end together.

But this is not seen, for this reason, there is a difference between the voltage web form and the current web form, and this difference is called the power factor angle, and when it is calculated with Cos, it is called the power factor.

Friends, if you read the above mentioned thing carefully, then you will know one thing that the story of power factor is only in AC supply and not in DC supply, as I told that when we connect the load with the supply  In such a condition, both our current and voltage reach the load in waveform and you know that AC has frequency due to which web form is seen in AC supply and there is no frequency in DC supply which  Waveform is not visible in DC due to

 As a conclusion, we can say that you will see the story of power factor only in AC supply, in DC supply you do not have to talk about power factor.

 Now let us talk about the web form of current and voltage of the three types of loads in electrical.

From the picture shown above, you can conclude that in resistive load there is zero degree displacement in web form of current and voltage, whereas in inductive load there is displacement of 90 degree in web form of current and voltage and in capacitive load also there is displacement of current and voltage.  and there is a displacement of 90 degrees in the web form of the voltage

 Current and voltage web form in the same direction in a resistive load

 The current in the capacitive load leads the voltage by 90 degrees

 Current in an inductive load lags the voltage by 90 degrees

 This means that the power factor in an electrical system will be talked about only when the electrical system is capacitive or inductive in nature.

 But now you will remember that above I told you that the capacity is not loaded in normal use.

 If I speak in simple words then it can be said that when our electrical system will be of inductive nature and alternating current will be flowing in it then only power factor will be talked about.

 Due to the inductive nature of the electrical system, there is a displacement of 90 degree in the webform of current and voltage. This 90 degree angle between current and voltage is called ¢ and if this value is placed with Cos, then the obtained value is called power factor. 

 Friends, power factor is the most important topic from the point of view of electrical, it is not possible to complete it completely in a single article, so I am going to post many more articles related to this, for which you can join my WhatsApp group to get the notification.  And you can join the Telegram group, I am giving you the link below.

In today's post, we have got answers to the following questions.

 What is power factor?
