HVDC outdoor test system

Customized outdoor application

Certain HV tests (e.g.: for overhead lines, insulator chains, etc.) are often carried out under outdoor conditions. For this purpose HIGHVOLT provides suitable outdoor test systems that are designed according to the proven circuit principles of an indoor test system. The outdoor test systems can be customized individually.


  • Special testing, e.g. for bipolar testing of overhead lines
  • For outdoor use even under unfavorable conditions
  • Wet and pollution testing
  • DC current measurements at high-voltage potential


  • Economic power transmission over very long distances
  • Full outdoor design
  • Designed for continuous operation
  • Low ripple (≤ 3 %)
  • Low PD level
  • Maintenance free
  • Low life cycle costs
  • Time saving due to automated testing
  • Automated earthing system
