Partial Discharge Monitor for Transformer Condenser Bushings

Essential in asset management, HVEX's PD Monitor is an advanced solution for power transformer monitoring, designed to detect and assess faults in high-voltage bushings and windings. It performs online measurements of partial discharges, capacitance, and dissipation factor in condenser bushings, providing information about insulation status and facilitating preventive maintenance management, helping reduce unplanned outages. The system provides alerts for possible internal insulation damage that may compromise the physical integrity of the bushing and transformer. These indications support technical assessment and maintenance actions to mitigate severe failure risks, including explosions; monitoring does not guarantee prevention of these events.
