Equipments Overview
Application: It is used to detect the transient over voltage of the components and the electrical clearance and the creepage distance.
Test sample: Household appliance, Audio, video and similar electronic apparatus.
Feature: This impulse voltage tester is a standard lightning wave test device with waveform 1.2/50µs. front time is 1.2µs, time to half value is 50µs, it is a destructive tester. The sample breakdown will produce a spark and acoustic, instrument peak voltage than the no-load voltage is decreased substantially (close to zero), when applying the same voltage in the next test, it will also show the above phenomenon.
