SA type impulse current test systems can generate different types lightning impulse current shapes such as 4/10μs, 8/20μs, 1＜20μs, 30/80μs, 60/100μs , long duration current according to IEC 60099-4. 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.
