Three-phase VARs (volt-ampere reactive) refer to the reactive power in a three-phase electrical system, which is crucial for maintaining voltage levels and ensuring the efficient operation of electrical equipment. Reactive power does not perform any real work but is essential for sustaining the magnetic fields in inductive loads like motors and Transformers. In a three-phase system, VARs help balance the power factor, improving energy efficiency and reducing losses in transmission and distribution networks. Proper management of VARs is vital for power quality and system stability.

What is vars generator?
A VARS (Variable Air Volume Rooftop System) generator is a type of HVAC system designed to control the volume of air supplied to different spaces within a building. It adjusts airflow based on the specific heating or cooling needs of each area, enhancing energy efficiency and comfort. By modulating the air volume, VARS generators help maintain consistent indoor temperatures while reducing energy consumption. They are commonly used in commercial buildings for improved climate control.
What is the characteristics for a generator on a full load?
What characteristics are you looking for? At full load, a synchronous generator will be spinning at synchronous speed, providing real power (watts), and likely some reactive power (vars), or it may be taking reactive power from the system to help hold the system voltage down under light loading conditions.
For 250 KVA transformer how many KVAR to be paralleled for no load loss?
No load losses are real power losses (in watts, not vars), so I'm not sure what you're talking about. If you're trying to parallel a transformer with another one to try to cancel out no load losses, you can't do this. These losses are also called core losses and are the price you pay to energize a transformer.
What is the difference between watt meter and kvar meter?
the difference is that the former is fitted with some type of registration mechanism whereby all the instantaneous reading of power are summed over a definite period of time whereas the latter indicates the value at particular instant when it is read.
Why electric generator drop the load?
Too much load for the generator, the generator began to under speed / overspeed, the governor / part of the generator went into failure, the generator capability was not up to the requirements placed by the system (needing to push out/pull in too many VARs), etc. there are many reasons for a generator to drop a load. Because a load dropped, this does not infer that the generator was the cause either (fault on the system, system instability limits reached, system protection tripped - non-generator related protection).

Will the variance of the difference of two independent normally distributed random variables be equal to the SUM of the variances of the two distributions?
Yes it is. That is actually true for all random vars, assuming the covariance of the two random vars is zero (they are uncorrelated).
What is the Reactive power in a capacitive modeand inducitive mode?
Generators can be required to generate real and reactive power. When operating in a leading mode, the generator is generating real and leading reactive power (inductive power). This means the generator is "sucking in VARS", which will pull down the terminal voltage similar to an inductor. It can also be operated in a lagging mode, which means it is generating real and lagging reactive power (capacitive power). The generator, then, is "pushing out VARS" like a capacitor, which will cause the terminal voltage to increase. Generators can only create so many leading and lagging VARs; in general lagging VARs are limited by the automatic voltage regulator output capabilities; leading vars are limitted by how much heat the stator can dissipate.
