EFT61004TA electricity instantaneous pulse group generator EFT61004AT

The cause of rapid transient pulse group: When an inductive load (such as relay, contactor, etc.) is turned off, due to insulated breakdown or contact bounce of the switch contact gap, transient harassment is generated at disconnected. When the inductive load repeats, the pulse group will repeatedly appear multiple times in a corresponding time gap. Test purposes: In order to verify the performance of the equipment in the influence of such transient harassment. It is generally considered that the electric fast instantaneous pulse group will cause the device to malfunction, because the pulse group is charged to the semiconductor junction capacitance in the line, and when the energy on the junction capacitor is accumulated to a certain extent, it will cause misuse of the device. Specifically manifested as a communication interruption, crash, software alarm, control and storage function loss during the test.
