Primary Test System for Substation Equipment

  • This primary current injection testing system is designed to perform primary tests requested in substations commissioning. It allows to perform accurate tests on CTs, VTs, PTs and ground grid.

  • Primary injection testing capabilities up to 3000 A with the optional module BUX 3000.

  • Power dissipation factor test with the optional module TD 5000 (voltage up to 12 kV).
