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
