Title

3 Phase Squirrel Induction Motor

Brief Introduction

When the direct axis transient or subtransient reactances are specified having regard to the operating conditions, the following values should be agreed upon:

– a minimum value of the direct axis subtransient reactance at the saturation level of rated voltage;

– a maximum value of the direct axis transient reactance at the unsaturated conditions of rated current.

Since the two reactances depend to a great extent on common fluxes, care should be taken to ensure that the values specified and agreed upon are compatible, that is, that the upper limit of the subtransient reactance is not set too close to the lower limit of the transient reactance.

When the value of the direct axis subtransient reactance is not specified, it shall be not less than 0,1 p.u. at the saturation level corresponding to rated voltage. The value of each of these reactances may be specified and agreed upon at another saturation level in accordance with IEC 60034-4. If it is agreed that values are to be determined by test, the test shall be in accordance with IEC 60034-4
