Free QuoteApplication and Significance The AC withstand voltage test is widely used in the quality inspection and safety evaluation of electrical equipment such as transformers, switchgear, cables, etc. It is a key link to ensure the safe and stable operation of power equipment.
A very high voltage (up to the range at which dielectric breakdown is likely to occur) is applied to determine the withstand voltage. The voltage is gradually increased and the point at which dielectric breakdown occurs is called the withstand voltage (limit voltage).
The technical specifications of AC/DC Withstand Voltage Test include test voltage range, test current range, test accuracy, leakage current monitoring, insulation resistance monitoring, display mode, safety protection and more.
In withstand voltage test, a high AC (or DC) voltage is applied to a test object. The leakage current that flows when the object breaks down is detected in order to determine whether the test was passed or failed. In other words, dielectric breakdown equals an increase in electric current.
Medium-voltage inverter-duty motors with a base rating that exceeds 600 V must be able to withstand a peak voltage equal to 2.04 times the motor's rated line-to-line voltage. Rise times must equal or exceed 1 microsecond. Inverter-duty motors are also designed for wider constant-torque speed ranges than can be provided with a general-purpose motor.
When operating AC/DC Withstand Voltage Test, the following points should be noted: proper grounding connection must be made to ensure the accuracy of test results and the safety of the operation personnel.
