Product description:

Variable frequency resonant system (on-site test)

Variable frequency resonant system for testing of long HV cables and GIL, for testing of short HV cables and GIS/ GIL and for testing of long MV cables are designed for the generation of alternating current (AC) high voltage (HV) by resonant circuits with variable frequency, available of outdoor design.

Application:

  • On-site testing of XLPE terrestrial and submarine cables according to IEC 60840 and IEC 62067
  • On-site testing of GIS according to IEC 60517 and IEC 62271-203.
  • On-site testing of transformer according to IEC 60076-3
  • Withstand voltage testing
  • Partial discharge measurements
