National Field Services - partial-discharge-techniques

Causes of Switchgear FailureWhat Is Partial Discharge Measurement?Surface Partial DischargeInternal Partial DischargePD activity is a major cause of the long term degradation of insulation in HV and MV switchgear. Experience indicates that PD activity is a factor in around 85% of disruptive substation failures. Standard maintenance procedures are unlikely to detect the degradation of insulating components, which are associated with the aging process and are the most common cause of unexpected failures, especially if triggered by environmental or electrical stresses. The majority of the degradation processes affecting insulating components, such as bushings, cable terminations, current and potential transformers, are associated with PD activity. This can be defined as a localized electrical discharge in an insulation system that does not completely bridge the electrodes. PD activity associated with the aging and degradation of insulation typically increases with the evolution of the defect. Therefore, the measurement of PD activity can be used as a diagnostic tool, to assess equipment condition and...Get price

Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price
