kVA is the unit for apparent power. Apparent power consists of active and reactive power. Active power is the share of the apparent power which transmits energy from the source (generator) to the user. Reactive power is the share of the apparent power which represents a useless oscillation of energy from the source to the user and back again. It occurs when on account of some »inertia« in the system there is a phase shift between voltage and current. This means that the current does not change polarity synchronous with the voltage. But the heat generated in a winding as well as the eddy current losses generated in a transformer core depend on the current only, regardless of whether it aligns with the voltage or not. Therefore the heat is always proportional to the square of the current amplitude, irrespective of the phase angle (the shift between voltage and current). So a transformer has to be rated (and selected) by apparent power. Answer We define "complex power" as voltage times current (V*I), and thus the unit for power is the Volt-Amp (VA). When a circuit contains non-resistive elements (such as transformers), there is a component of power called "reactive power", which is power that is transmitted as a result of energy stored in inductors and capacitors. Reactive power does no useful work. Complex power is the sum of reactive power and real power (power which does work). When only real power is considered, the unit of power is the Watt. Transformers are rated in VA and not W because heat generated by electricity flowing through a conductor is proportional to the current flowing through the conductor. Although reactive power does no work, the current exists nonetheless and must be accounted for when selecting the proper sized wiring.

Kv and kvar and kva what different?

  KV is the unit used for VOLTAGE measurement.   AC power is complex quantity that is it has both magnitude and direction and hence has two parts real part and imaginar

How can calculate kw and kvar?

There are numerous ways of doing this; it depends on what information you are give to start with.  One method is: power = apparent power x cosine (phase angle) reactive power

What is KVAR?

Answer   KVAR Kilovolt-Ampere Reactive   KVAR Kilovolt-Ampere-Reactance   {|  ! Acronym  ! Definition  |  Formular for calculation of kvar  |}

How do you calculate kvar of capacitor bank?

Your question is rather vague. Are you asking how do you determine the reactive power of a capacitor bank necessary to improve the power factor of a load (in which case, is it

What is the difference between kvar and kva?

On the ligher side: (Norwegian has got two forms. Bokmål and Nynorsk) In Nynorsk, Kvar mean the same as "Where?" and Kva mean the same as "What?".   Answer To an

How do you convert kvar to amps?

For single phase, RMS values of volts and amps: KVAR = kVoltage * Amps For three phase, RMS valuse of volts and amps, with voltage phase to phase: KVAR = kVolt * Amps * sqrt(3

What is the Formula to calculate KVAR?

  {|  |-  | capacitance of the capacitor is mentioned in KVAR. Formula : KVAR = KW*tan@ FOR tan@, First note the power factor & KW without connecting capacitor. The no

What is a kvar?

Kvar = Kilo Volt Amp Reactance.

How many kVA equal kvar?

KVA=√ (KVAR2 + KW2) So, KVAR = √(KVA2 - KW2) We know KW = KVA cos Φ => KVAR = √(KVA2 - KVA2cos2Φ ) = √KVA2(1- cos2Φ) = √KVA2(sin2Φ) = KVA sinΦ

How is KVAr calculation?

There are various ways in which you can determine the reactive power (in reactive volt amperes) of a load. From the practical point of view, you can use a voltmeter and an amm

How do you decide KVAR rating of capacitor bank?

  Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs wit

What is a reverse KVAR relay?

  The reverse KVAR relay protects a generator from a loss of excitation. When the excitation system is lost, reactive power will flow from the system back into the generat
