Detecting the cause of failures in insulated electrical equipment.
Partial discharge (PD) is known to be one of the foremost root causes of degradation and failure in insulated electric assets such as underground cables, transformers and gas insulated substation equipment.
Since PD is present and can be detected far in advance of equipment failure, continuous monitoring of PD allows the utility to repair or replace the effected assets before failure to ensure safety to its field crews and maximize reliability to its customers.
On-line PD monitoring allows asset managers to continuously monitor critical equipment condition under normal load and without interrupting service.
