Low voltage harmonic why can save electricity?

There is great harm to the power system harmonic, mainly for electronic equipment and high current rectifier will produce a lot of harmonic, harmonic control after the change me:

1 after treatment, the changes of the active power of P?

After treatment, the active power will not change, that is to say the user's actual consumption is not going to change.

The 2 harmonic why can save electricity?

(1) it simply be not energy saving. However, the harmonics, reduce the reactive component, but also can reduce the user to load transformer between the apparent power (as in the current), then,can reduce the user on the device input. A very simple example, such as the transformer before you is 500KVA to meet the requirements, may reduce the harmonic, 315 are met, the other circuit breaker, cables and so on can be reduced, so the actual investment Shi Bushi less?

(2) where the harmonic is easy to produce adverse effects on the equipment, especially theelectronic equipment and the compensation capacitor group. Can cause serious electronic equipment can not work, and the compensation capacitor group is damaged, I have seen theharmonic is too large, resulting in transformer explosion accident.

(3) the reactive component is too large, the power supply bureau is to be fined, but also an investment.

In summary, harmonic control in general users in fact significance, but for large harmonic sourceuser is very necessary.
