Partial Discharge is "A localised electrical discharge that only partially bridges the insulation between conductors and which can or cannot occur adjacent to a conductor" ---- quoted from IEC60270. When the Voltage stress exceeds the breakdown strength of that portion of the insulating material, a Partial Discharge begins and continues to deteriorate that insulation.

  • Analyze Electromagnetic

    PDetector - PMDT

    PDetector is the ideal partner for a condition based maintenance program by employing partial discharge detection. It integrates TEV, UHF, AE, Ultrasonic, and HFCT Sensors that offer additional condition assessment information and Health Indices (HI) for Medium and High Voltage Electrical Equipment. PDetector is the only handheld instrument with 5 sensor technologies in one instrument. This handheld device DETECTS the PD activity in numerical values and displays amplitude and period spectrums.

  • Partial discharge online monitoring system

    PDMonitor - PMDT

    PDMonitor, which utilizes TEV, UHF, AE, Ultrasonic and HFCT sensors, is customized to conduct real-time online monitoring to detect and locate the potential failures BEFORE they lead to breakdown in power assets and to provide maintenance suggestions.
