Why you take 0.95 as standard power factor?
When you need to calculate the estimated load or load current during initial design phase or so, you need to assume a value for power factor which is realistic. 0.95 is a realistic value.
How do you find whether it is inductor or capacitor if only power factor is given?
in case of inductor or capacitor power factor is always zero.as power factor is cosine of phase angle between voltage and current. in case of inductor and capacitor phase angle between voltage and current is 90 so it become zero so if given power factor is zero then it can be inductor or capacitor.
How do you design a transformer with three phase 400v input and single phase 2000v output?
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
How you improve power factor in synchronous motor?
Power Factor measures the difference in phase between the current and voltage. When they are in phase the Power Factor is defined as 1. When out of phase the value is less than 1. If they are 180 degrees out of phase the Power Factor will be zero.
What is the effect on the supply current if the capacitor is removed?
It depends on how the capacitor is connected and whether the supply voltage is a.c. or d.c. Assuming you are talking about a power-factor improvement capacitor (connected in parallel with an inductive load, supplied with a.c.), then the supply current will reduce.
How to connect 3 phase power factor correction capacitor?
how to connect power capacitor with 3 phase motor
What has the author A K Ahmed written?
A K. Ahmed has written: 'Power factor correction of single-phase rectifier circuits with non-sinusoidal supply voltage'
What is the design phase?
The design phase is CSS.
What is a correction factor capacitor?
i know that static capacitors are used to improve the power factor. power factor should be high. Static capacitor supplies lagging reactive power. That means; the current I has 2 components they are magnetising Im (watless or waste current) and useful current Iw. Iw is in phase with voltage and Im is 90 degree away. Phase angle between them is phi 1. power factor is given by cosine of phi 1. phi angle should be less so that cosine of phi is high. To make phi angle less we use capacitor; this is nothing but power factor correction and capacitor used for this is called power factor correction capacitor. now when a capacitor is connected, it induces a current Ic 180 out of phase from Im and less in magnitude from Im. therefore, now the magnetising current is Im1=Im-Ic. due to this the phase angle reduces to phi 2. now the new power factor is cosine of phi 2. it is improved power factor.
What are the major phases in MIS design?
design phase analyse phase
What are the uses of single phase or three phase motor?
torque load, generation load, power correction load
What do you do if the disk in your electric meter is turning in the wrong direction?
If this is a three phase VAR meter then you have a leading power factor. There is too much capacitive reactance in the distributions load. This could be from a power factor correction bank of capacitors that did not drop off line when the motor that they were correcting dropped out.
Why you take 0.95 as standard power factor?
When you need to calculate the estimated load or load current during initial design phase or so, you need to assume a value for power factor which is realistic. 0.95 is a realistic value.
What is the power factor when the current and voltage are in phase?
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
What are the steps involved in design stage of the software?
steps involved in design phase
What phase includes determining what you will do in the event a disaster should occured?
The design/planning phase.
How long does take to design a simple website?
There are so many routes for developing a website, different sites having different requirements, I am giving you a brief of them, the life cycle of web design are as follows: Phase 1 - Planning Phase 2 - Analysis Phase 3 - Design Phase 4 - Design Implementation Phase 5 - Testing Phase 6 - Implementation (Public Release) Phase 7 - Maintenance and Changes This is not compulsory that every-time you have to follow this trend only, requirements and planning matters, but the core steps are as above!
