After connecting the Primary Current Injection Test System

　　After connecting the Primary Current Injection Test System to the working power supply,the required high current for testing can be obtained by adjusting the output voltage of the voltage regulator 　　Actually,the statement seems a bit inaccurate.In a Primary Current Injection Test System,the high current required for testing is typically achieved by passing current directly through the primary winding of the equipment under test.This is done by injecting a high current directly into the primary side of the equipment.

　　Adjusting the output voltage of the voltage regulator in this context wouldn't directly control the current flowing through the primary winding.The current is usually controlled by the settings on the current injection test system itself.
