Sa Type Impulse Current Test Systems

We are indulged in manufacturing and exporting of SA Type Impulse Current Test Systems in Yangzhou, Jiangsu, China.

SA type impulse current test systems can generate different types lightning impulse current shapes such as 4/10I s, 8/20I s, 1i 20I s, 30/80I s, 60/100I s , 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.

Applications;
1) Residual voltage test of surge arresters;
2) 4/10I s impulse current test of surge arresters;
3) Long duration impulse current test of surge arresters
