| Note: When current is 0.2In~Imax, phase error(δe ) is the average of δmax and |
| δmin; When current is i, the phase error of i is the difference of betweenδi and δe. (△δi=δi-δe). |
| Sine-half wave test |
When currents is 31.8A, The electric energy measurement error introduced by current transformers is less than 3% |
