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 many capacitors are found in a 3 phase package unit?
The number of capacitors in a 3-phase package unit can vary depending on its design and application. Generally, these units may have one or more capacitors for power factor correction and motor starting assistance, often totaling between 1 to 3 capacitors. Some units might include additional capacitors for various control or filtering purposes. Always refer to the specific unit's manual for precise information.
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.
Why you use capacitor in 3 phase motor?
Capacitors are used in three-phase motors primarily for power factor correction and to improve the efficiency of the motor. In specific applications, such as single-phase motors or when starting a three-phase motor with an unbalanced load, capacitors can provide the necessary phase shift to create a rotating magnetic field. This enhances starting torque and ensures smooth operation. Additionally, capacitors help stabilize voltage levels, reducing the risk of overheating and prolonging the motor's lifespan.
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 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 is the design phase?

What are the uses of single phase or three phase motor?

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.

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).
How does power factor correction solve the problems caused by inductive loading?
You calculate power by multiplying voltage x current x Power Factor (PF). PF = 1 for a resistive load so you essentially convert maximum power with a resistive load. With an inductive load the PF decreases from 1 toward zero. Hence the lower the power factor the less efficient the system. This reduced PF is caused by the current and voltage sine waves being out of phase. If they are 180 degrees out of phase you have zero PF. PF correction involves circuitry that basically helps "tune" the circuit to reduce the lag. Capacitors are involved heavily in this process to tune the circuit.
