Ways to Improve Power Factor ગુજરાતી માં માહિતી માટે અહીં ક્લિક કરો  हिन्दी में जानकारी के लिए यहाँ क्लिक करे                  Two ways are used to improve the power factor, as follows By combining the       1.capacitor into the parallel of the load                This is one of the easiest and easiest ways to improve the power factor. The capacitor always takes the leading current. This eliminates leging currents and improves the power factor.       2.Cicronas motor connection                            The power factor can be upgraded by running the cicronas motor in parallel with over-extension on the line which is to be upgraded in the power factor. Now this is very expensive in the motor cost, where it is used only when there is more advantage in comparison with its price Should be done       3. Using a phase adwanser can also be improved in the power factor

                  The machine which is converted into energy from the DC DC in the form of DC energy is called a DC motor, its working principle is as follows when the current carrying conductor is placed in the magnetic field, it feels a mechanical force, whose direction is flaming The right hand side can be shown as per rule                  The vision of the composition is that there is no difference between the DC generator or the DC motor, ie the use of DC generators can be used as a DC generator, DC motor and DC motor are only slightly different in the outer appearance. Generator frames are open type When the motor's frame is of close type, DC motor like the DC generator also has a shunt wound, a series wound, and a compound wall type.                       Fleming is the clock vise  direction of rotation of the motor of the left-hand rule, but the conductor's magnetic field have to cut prices in the opposite direction of the basic electric current flowing in the

Advantages of Having a High Power Factor The voltage of the machine, lamp, etc. can be maintained by maintaining the voltage of a constant value. And therefore increase in their efficiency Voltage regulation gets better Transmission and distribution line losses decrease, which means increase in efficiency The overhand protector of the conductor is protected A low capacity circuit breaker, switches, fuses and condensers can be used for a given load The user has to pay a lower price for his load ગુજરાતી માં માહિતી માટે અહીં ક્લિક કરો  हिन्दी में जानकारी के लिए यहाँ क्लिक करे 

cycle               The value of alternating zodiac sign and a complete change in direction is referred to as a bicycle. Frequency               The number of cycles per second is called frequency. It is seen separately in different countries. India is usually 50 c / s frequency. Period              The time taken to complete a cycle is called a period Technical value              The value that is received at any time is called the value of the value Maxim value               The maximum value of the zodiac sign during the given time period is called a maximum value and the peak value of the other is also Average value                  The average value of the typical values ​​found in the semi-cycle is called its average value, which is also called the average value. Phase                  An orgular displacement of two or more alternating zodiac is called phase Enough                If the maximum or minimum values ​​of two alterative ones occu

Power factor:                        The power of true power and the power of aprent power is called power factor.                                           That is, the power factor = true power / simulatory power                                                                                                               Where true power means the reading of the watts meter                                                            And simulatory power means the volt meter and ammeter's reading                                                            I.e. pf = w / vi                                            That is, the value of the power factor is the cosine of the phase angle between voltage and current. Impact of Low Power Factor (In Distribution System):                            Distribution method increases the power factor as the power factor decreases, Increasing the current increases the amount of power consumed in the line and increases the voltage

The composition of DC motor    Theory                     DC motors operate on the principle of transformation in the electrical power of electric power,   Parts of DC Motor                                         Parts of DC motors are divided into two sections                                                          1. moving parts  and 2. Fixed part Moving part    Armature:                    It consists of conductors and a computator in the form of laminated core or sounding of magnetic material, slot mounted in the armature core, in which the conductor is placed in the form of coils.                    The function of the armature is to rotate in the Uniform Magnetic Field  Commutator:                   Commutator copper is of ring type but it is a combination of small pieces. One piece is called a segment. Each segment is insulated from one to another and tightly combines many segments, it is fitted on the armature insulated shaft and it is computat

DC generator and motor                           The machine mechanical power (mechanical power) that is converted into DC electrical power is called a DC generator, when the machine or machine DC is converted into electrical form in the form of mechanical power, it is called a DC motor, There is no difference between creation of DC generators and DC motors, both of which differ only in their work culture
