Calculate according to the protection type (1) an single phase motor electric current flows through the current transformer ratio; (2) according to the model of current transformer, variable ratio and a current ratio, on the 10% error curve to determine the permission of the current transformer secondary load; (3) according to the most severe type of short electric generator circuit current transformer secondary load, the calculation of current transformer actual secondary load; (4) the practical secondary load and allow the secondary load. Such as the actual secondary load is less than the allowed secondary load, said current transformer error less than 10% error: 1) increasing the connection wire section or shorten the connection wire length, Three phase motor to reduce the actual secondary load; 2) choose larger current transformer, reduce a current ratio, increase to allow secondary load; 3) the secondary winding of current transformer in series, a doubling of allowing the secondary load.
