Why do Partial Discharge Testing? PD activity in your plant is considered as an early indicator of insulation degradation which can ultimately lead to major equipment failure. It is vital to detect Partial Discharge early to ensure corrective action can take place before a potentially catastrophic failure occurs.
Doing Partial Discharge testing early on can allow you to make an informed decision about the maintenance, repair or replacement of your switchboards. This is a much more economic and time-saving option than emergency replacement of your switchboards and the costly downtime that follows from a site failure.
As PD can also be observed, occasionally, during the commissioning of new equipment, we can also offer Partial Discharge testing as part of the commissioning of any new or refurbished equipment.
