full-load, the total harmonic capacity of phase voltage wave form is not
more than 3%, each harmonic capacity is not more than 2%, deviation is
nor more than 4%
2. Voltage modulation is not more than 1%;
3. At 15% asymmetrical load, the unbalance of 3-phase voltage is
not more than 2%; At 25% asymmetrical load, the unbalance of 3-phase
voltage is not more than 5%;
4. At the asymmetrical load phase shift on null point of the
3-phase voltage wave form shall be within 120 +/- 2 degrees;
5. The stable voltage regulating ratio is nor more than +/- 1%;
6. The transient voltage regulating ratio at revulsion rated
power load is not more than +/- 15% or +/- 20%, the stable time is not
