The resulting figure will also help you work out the true power in watts of the given load. When you determine what the reactive power is, you can find the right capacitors necessary to lower apparent power components in your systems.

The apparent power supplied by the utility, on the other hand, will drop to about Reactive power is the unused power generated by reactive components in an AC circuit or system and is measured in KVAR.

In terms of the power factor, the greater the reactive power is, the higher the apparent power or kVA is as well. Commercial and industrial electric firms, though, consume this in massive amounts, so electricity companies charge them a premium. In reactive power formula, X refers to the reactance of the circuit and I is the current that runs through the circuit. Before you understand how the KVAR power factor works, you need to be clear about what the power factor is.

It is essentially a measure of how effective the use of incoming power in your electrical system is. The ratio is working power to Apparent or total power. That is the power factor formula. To understand what the power factor correction KVAR is, remember that the power factor is the ratio between real and apparent power. The outcome gives you a poor power factor. On a large system you would not see a voltage change but you would see a change in VARs when the lights were on.

You have to consider all the loads connected past the EV. Do you know if the voltages and currents are sinusoidal and steady state? If not, perhaps look for some waveforms in your equipment, or better yet put a scope on it at the locations where your installed meter senses. That will probably reveal the details. If not, that would be time to investigate the meter details. Presumably the EV has its own microprocesser controlled charger which is some kind of thyristor or IGBT circuitry, probably a proprietary system.

THe AC current waveform as mentioned by electricpete is likely quite distorted, not a sinewave. Possibly giving some very odd readings. Or was it something supplied with the EV? Take all this fancy technology with a large bit of skepticism. Can get quite complicated quickly. One thing to note - there are 5 different definitions given sections 3. As noted by Raveski, you have complicated non-passive load.

It is probably adjusting firing cycles as the voltage varies, so not truly steady state and not truly periodic. Red Flag This Post Please let us know here why this post is inappropriate. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
