Partial discharge (PD) detection is valuable techniques you can use to assess asset condition. ENGIS offers a complete range of Doble’s PD analysis tools that can be used while equipment remains in service. This non-invasive testing allows you to find early indications of deterioration giving you time to plan a course of action for further testing, maintenance or eventual replacement. These tools are a cost-effective addition to a proactive condition-based maintenance program.
What is Partial Discharge (PD)?
Partial discharges are small electrical sparks that occur within the insulation of medium and high voltage electrical assets. Each discrete partial discharge is the result of an electrical breakdown of an air pocket within the insulation. These discharges erode insulation and eventually result in insulation failure.
