APM7000&APM7000P is the most effective insulation diagnosis system that analyzes the cable’s failure phenomenon due top artial discharge in real time to prevent accidental power failure.

  • Localized defects of insulation system cause Partial Discharge. Electric trees which is made by Partial Discharge can lead to insulation breakdown.
  • Partial Discharge measurement is useful method to decide how much systems are degraded by electrical and thermal stress, manufacturing defects and installation errors in cable insulation system.
  • APM7000P is designed as compact size for portable PD measurement and enabled to operate for continuous monitoring without computer. This equipment aims at preventing electrical accidents of cable through identifying insulator faults in advance.
