About Megger Partial Discharge Detectors
Megger Partial Discharge (PD) Detectors are specialised instruments designed to detect, locate, and assess partial discharge activity in electrical insulation systems. Partial discharges are localised electrical discharges that only partially bridge the insulation between conductors and can be indicative of insulation defects, which may lead to equipment failure if not addressed.
What Do Megger Partial Discharge Detectors Measure?
Key measurements include:
- Presence and Occurrence of PD: Detects if PD is occurring within the insulation.
- PD Intensity/Magnitude: The intensity of the discharge, typically measured in picoCoulombs (pC).
- PD phase: The phase angle at which the discharge occurs relative to the applied voltage waveform.
- PD frequency spectrum: The frequency distribution of the discharge signals, which helps in noise filtering and identifying discharge sources. Ultra-high frequency (UHF) detectors, such as the UHF Partial Discharge Detector, are particularly effective in identifying PD in GIS and other enclosed HV equipment.
- PD patterns: Phase-resolved partial discharge (PRPD) patterns, which help classify the type of defect (e.g., corona, surface discharge, or internal discharge).
Where Are Megger Partial Discharge Detectors Used?
Megger PD detectors are utilised across various high-voltage applications, including:
- Power Transformers: To monitor insulation conditions and detect defects in bushings, windings, and other components.
- Switchgear and GIS (Gas-Insulated Switchgear): To identify partial discharges in MV and HV switchgear, preventing unplanned outages.
- Cables: Evaluating the condition of high-voltage cables and their accessories.
- Rotating Electrical Machines (Motors, Generators): Detecting PD in stator windings and rotor insulation of motors and generators, preventing motor and generator failures in critical industrial processes.
- Substations: For non-invasive surveys of HV components like cable terminations, surge arrestors, and isolators.
