Partial Discharge (PD) is the term used for the electrical discharge that can occur in a localised area between two conducting electrodes, as can arise due to insulation system imperfections or discontinuities.
The right PD survey can thereby serve as a reliable indicator of a given insulation’s state of deterioration and the wider risks that may be resultantly posed to such high voltage plant as cables and cable accessories, switchgear, motors and generators and power transformers and bushings.
With its exceptional reputation for catering to the most specialised requirements for niche, high-tech engineering know-how, Power Technical Services conducts the PD surveys that may be crucial to safeguarding the reliability and longevity of your high voltage electrical assets.
For over 50 years, PD testing has been performed on electrical systems for the purposes of ongoing predictive maintenance. Such surveys can play an integral role in providing the data that enables your organisation to assess the present quality of your system’s insulation and its impact on the broader health of your equipment.
PD surveys are especially important when your high voltage asset is critical to a network’s operation, whether due to the age of the asset, previous failures or the financial implications of such a failure.
It could not be more critical for those overseeing the most bespoke, high voltage engineering projects to ensure that an appropriate PD survey has been undertaken to identify such potential issues as poor design, improper installation or simple deterioration with age that can contribute to premature failure.
Don’t take unnecessary risks with the health of your high voltage electrical system. Contact our highly regarded specialists in bespoke engineering projects at Power Technical Services, and you can better protect against the erosion and eventual failure of your system insulation, while helping to predict the future performance and reliability of your associated critical assets.
