PD Detector

  1. - PDetector is the ideal partner for condition-based maintenance programs. Online partial discharge testing is a method of inspecting the insulation of electric power systems while equipment remains energized and in service. PDetector incorporates all 5 types of online PD sensor technology.
  2. - Information from multiple sensors gives PDetector the versatility to detect all types of PD in all types of substation apparatus. Furthermore, the exact type of PD activity can determined using PRPS: void, corona, surface, particle, or floating electrode.
  1. - Power cables
  2. - Transformers
  3. - GIS
  4. - Switchgear
  5. - Substation Apparatus
  6. Sensor Technology : Detection Bandwidth
  1. - TEV – Transient Earth Voltage (built-in to main handheld unit) 3㎒ - 100㎒
  2. - UHF – Ultra High Frequency 300 ㎒ - 1.5 ㎓
  3. - HFCT – High Frequency Current Transformer 500㎑ - 50㎒
  1. - Acoustic Contact 20㎑ - 300㎑
  2. - Airborne Ultrasonic 40㎑
  1. Phase Resolved Partial Discharge(PRPD) – PD activity produces both electromagnetic and acoustic emissions. PRPD mode will automatically relate the occurrence of the incoming signals to the power frequency 60Hz (or 50Hz). This gives the user the ability to instantly determine if PD is present.
