KSG3200 SYNCHRONIZED PRIMARY/SECONDARY LOAD AND PROTECTION RELAY TESTING INSTRUMENT

New Products / New Technology

The KSG3200 is a multifunctional, integrated testing device developed for both primary and secondary tests. It supports primary‑side current injection testing of instrument transformers, eliminating the need for separate current‑boosting or voltage‑boosting equipment. Its current output capabilities include 3 × 300 A and 1 × 600 A, meeting the demands of on-site high‑current testing. The device also supports loaded‑condition testing and high‑current output operations. Notably, it features an innovative dual‑terminal synchronous high‑current output function, specifically designed for synchronized optical differential protection commissioning—both within and outside substations. This groundbreaking feature has been adopted by a State Grid subsidiary as a core component of its technology project and was awarded the Second Prize for Scientific and Technological Innovation.
