H Type Impulse Current Test System - China

Application

H Type impulse current test system can generate different types lightning impulse current shapes such as 4/ 10μ s, 8/ 20μ s, 1＜ 20μ s, 30/ 80μ s, 60/ 100μ s , long duration current according to the customers’ requirement.

Modifications can be applied according to the request of our customers.

This type of test system is especially to test the metal oxide surge arresters.
