The inductive load will generate a back-EMF voltage at the monment the power is turned on.The peak value of this voltage is far greater than the voltage that the load AC power supply can withstand,so it is easy to cause the instantaneous overload of the star-delta starter cabinet,which will affect the service life of the star-delta starter cabinet.
Therefore,the required star-delta starter cabinet needs to be amplified by one gear.
For example,a 15KW motor needs a 18.5KW star-delta starter cabinet,and a 18.5 motor needs a 22KW star-delta starter cabinet.
