Test Equipment Description

3ctest SGN 3483T is designed to conduct surge test of combination wave. It is used to isolate surge signal. When using normal three-phase mains network, voltage wave tail attenuates too fast, which cannot meet the requirements in standards. Performance of this network can meet GB/T3483. It is featured with stable performance, powerful load capacity during coupling/decoupling test for 4/300μs and 10/200μs voltage wave. It can be equipped with SG-5020G surge test system to prevent damage by surge signal.
