APM2000 Portable PD Monitoring System

BrochureDOWNLOAD

APM 2000 detects and alerts various defects inside EHV/MV equipment by analyzing UHF signals generated by partial discharge. It monitors, records and analyzes PD signal continuously and alerts the condition of EHV/MV equipment with light-weight and small-sized equipment.

  • Suitable for the PD measurement of the extra-high voltage and medium voltage equipment
  • Portable light-weight and small-sized equipment maintain PD analysis features
  • Provides project management features for multiple PD sensors at multiple sites.
  • Able to detect less than 5 pC according to CIGRE TF 15/33.03.05
  • Compliant with EMC and electricity safety international standards such as IEC61000-4-X, IEC60255-5, IEC60068-2-X, IEC60529/2001, IEC60270, and CISPR22
