The reason electricity is trsnsmitted at very high voltage is to reduce energy loss. As Power = V x I and heat loss = I2 R. Thus if I the current is low the energy lost in the transmission cables will be minimal. The reason electricity is trsnsmitted at very high voltage is to reduce energy loss.

What is the kw of 100kva transformer and how you calculate?

The kW rating of a transformer can be calculated by multiplying the kVA rating by the power factor. For example, if the power factor is 0.8, then the kW rating of a 100 kVA transformer would be 80 kW. You can also use the formula: kW = kVA x power factor.


Is there a difference between KW and kW?

AnswerKiloWatt hours. Its a measure of energy use. It is the amount of power used over time.Energy is the ability to do work, while power is the rate at which work is done.Your water heater may have a power rating of 5 kW. If it runs for 8 hours in a day, you would use 40 kWh of energy doing the work of heating the water.


How many KW is in 150 KVA?

It depends on the power factor, which depends on the reactance of the load.For a typical power factor of 0.92, 150 KVAR translates to 383 KVA, which translates to 352 KW.Power factor is the cosine of the phase angle (theta) between voltage and current. KVA times cosine (theta) is KW, while KVA times sine (theta) is KVAR.


How many watts is 1.60 kw?

where, prices vary from region and power company get hold of a power bill The question should be: How much does 1.6 kWh cost. A kW is a measurement for power. The energy bill will increase if you sustain this power for a longer period (hence the h after kW, for hour).


How do you change ac tonnage to kva and kw?

To convert AC tonnage to kVA and kW, use the following formulas: For kVA: kVA = (tonnage x 3.517) For kW: kW = (tonnage x 3.517 x power factor). Remember to consider the power factor of the system when converting from tonnage to kVA and kW.

How convert Hp to kW?

The question cannot be answered. It would depend on what device you are using to do the converting. [edit] Well, in the simplest terms: Power (kW) = Power (HP) x 0.7457 Power (HP) = Power (kW) x 1.341


Why you take energy bill in units of energy instead unit of power?

Energy bill must be in terms of Energy unit (KWH) only. Energy is KW (power) utilized over a period of time. The unit of energy is Kilowatthour (KWH) Unit of power is Kilowatt (KW) KW is instantaneous power being utilized. KW (power) over a time period is Energy (KW H)


6000VA Inverter is how many kw?

KVA=KW*Power factor, considering PF 0.9, 6KVA=KW*0.9 KW=6/.9=6.67

How do you calculate condenser capacity?

condenser capacity(kw) = compressor cooling capacity (kw) + compressor input (kw) power condenser capacity(kw) = Pf + Pa


How do convert KVA to KW?

kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.


How motor kw is been decided?

You can measure the output power of the motor (mechanical power or shaft power) by a speed and torque sensor. The product of speed (angular velocity to be precise) and torque is power. Is this case the output power. The SI unit of power is W, kW is 1000 W. So the power/1000=power [kW].
