Chart value of 1.2A/HP multiplied by 275 HP = 330A. 330A X 1.25 = 412.5A. Closest standard current transformer ratio is 400/5. For single-phase motors, determine full load current from the nameplate rating. Multiply by 1.25 to get the approximate CT rating, as shown above. ...
We ultimately need to arrive at a kVA value. If only amps are known, use the full load chart or the following formulas. Single-phase “kVA” = Volts (load) x Amps (load) / 1000 Three-phase “kVA” = Volts (load) x Amps (load) x 3 /1000 Where 3 = 1.732 4. What is the fre...
Enter the voltage driving the MAX13256 VDDpin in spreadsheet cell C7. For this example, it is 26V. Enter the output load current in cell C8. According to this example, it is 0.5A. The transformer specification is used to enter the corresponding data in cells C9 through C12. Figure 3. ...

the 5x full load current refers to the manufacturers rating of a maximum inrush current of 5 x the full load capable of the transformer. full load is approximately 320A therefore 5 x is 1600A. you then square this number and multiply by 0.1 secs. my question is really how do you calcu...
Flow chart of presented algorithm. For different conditions of the test set, fault current magnitude, load condition, remanent flux, and switching angle are changed to investigate the effects of these factors on the performance of the proposed algorithm. Since the wave-shape of inrush current chan...
