How to determine the capacity of active power filt

1. Through the actual measurement of the power system, the harmonic currents,such as the measured current distortion of a system in the total rate of 25%, the total current is 1000A, the total harmonic current is 1000A x 25% = 250A, such as the 1.25 times harmonic margin calculation, namely 250A x 1.25 = 312A,selection of ZN-APF-3L-300A models can be my company's existing productsproducts. (harmonic current test equipment for FLUCK, CA, HIOKI and other related professional electric energy quality tester)

2. If it is to add new load or a new design, you need to estimate the capacity of active power filter. The most important is the estimation of nonlinear load,according to the experience, three-phase rectifier bridge power inverter and UPSas well as the general diode, the total current distortion rate is in commonly 25 ~ 35 (%), special may have about 45%, according to the load rated current value can be calculated from the harmonic current.

      Harmonic current = load current ratings * (25 ~ 35)%
3. If more than one type of load parallel operation, according to the root mean square method to calculate the total harmonic current value.

Total harmonic current value = sqrt

I1---- harmonic current of nonlinear load first

I2---- harmonic current load second nonlinear
In---- harmonic current load nonlinear n station
