What is a voltage drop test?
Voltage drop test items: the voltage temporary drop and short time interruption, the voltage temporary drop and voltage interruption are caused by the failure of the power grid and power facilities or the sudden large changes in the load.
Voltage changes are caused by continuous changes in the load connected to the power grid.
If EUT cannot respond to the supply voltage, it may cause failure.
Definition and detection method of voltage drop:
See the instructions in IEC61400-21-2008.
Refers to the power supply voltage suddenly drops from the rated value to a certain potential point, which will cause a sudden change in the line current of the electrical equipment, forming potential impact damage, can use the intermediate transformer or converter to limit the impact of electric energy.
