Best Way to Manage Risk of PD

Time base maintenance is not an effective way to manage the risks associated with MV/HV equipment.

Continuous monitoring of MV/HV equipment is the most effective way to detect issues early, allowing for intervention prior to a catastrophic failure.

How much does PD actually impact MV/HV Equipment?

Estimated that 85% of catastrophic failure in HV/MV equipment is caused by PD.
